Not every TV comes with Bluetooth built in, and that is exactly the problem the best TV Bluetooth transmitters solve. Whether you want to watch late-night movies without waking the house, connect your AirPods to an older flat screen, or share audio with two pairs of headphones at once, a dedicated transmitter is the simplest fix I have found.
Our team tested 10 of the most popular Bluetooth transmitters for TV across optical, AUX, RCA, and coaxial connections over several weeks. We paired them with everything from Bose QC45 and Sony WH-1000XM5 headphones to budget earbuds and hearing aids. We measured range through walls, tested latency against lip movements, and checked whether dual-link actually worked as advertised.
If you are also shopping for headphones to pair with your transmitter, our guide to the best wireless gaming headsets covers several Bluetooth-capable models that work great with TV transmitters. And if you want to keep things ultra-affordable, our roundup of budget Bluetooth adapters under $20 has some surprisingly capable picks.
What we learned is that the right transmitter depends heavily on your TV’s available ports, the headphones you already own, and whether you need features like soundbar passthrough or hearing aid compatibility. Below, I break down every product we tested so you can pick the one that fits your setup perfectly.

164ft Range
I set up the Avantree Orbit Pro on a Samsung QLED TV using the optical TOSLINK connection, and within two minutes both my Bose QC45 and my partner’s AirPods Pro were paired and streaming simultaneously. The LCD screen makes a bigger difference than I expected. Instead of guessing which devices are connected, you see everything listed clearly on the front panel.
The remote control is what truly separates the Orbit Pro from the pack. Being able to adjust volume without reaching for the TV remote or taking off your headphones sounds minor, but after a week of late-night viewing, I cannot imagine going back. The Reddit community flagged this exact feature as a dealmaker, and I completely agree.
Range was outstanding in my testing. I walked to the kitchen about 40 feet away through two drywall partitions, and the audio stayed perfectly intact. Avantree claims 164 feet line-of-sight, and while I could not test that exact distance, the real-world range through walls exceeded every other transmitter in this roundup.
One standout feature is the Dolby Digital and DTS surround-to-stereo conversion. Many TVs output 5.1 surround sound through optical, which causes silence or static on Bluetooth headphones. The Orbit Pro handles this conversion automatically, so you get clean audio regardless of your TV’s output format.
Who should buy the Avantree Orbit Pro
This is the transmitter I recommend for home theater enthusiasts who want maximum control. If you have a surround sound system, need soundbar passthrough, and want a dedicated remote for volume, the Orbit Pro justifies its premium price. It is also excellent for households where multiple people listen at different volumes.
Who should skip the Avantree Orbit Pro
If you only need basic TV-to-headphone audio and do not care about an LCD screen or remote control, you can save significant money with the Audikast 3 or Oasis Plus 2. The Orbit Pro’s extra features are genuinely useful, but not everyone needs them.

Class 1 Range
The Avantree Oasis Plus 2 is the transmitter I recommend to most people, and with over 7,000 reviews backing it up, I am clearly not alone. I connected it to an LG OLED TV via optical and was streaming to my Sony WH-1000XM5 within seconds of plugging it in. The plug-and-play simplicity is exactly what most buyers want.
The killer feature here is optical passthrough. This means you can send audio to your Bluetooth headphones AND your soundbar at the same time from a single optical output. For households where one person wants headphones and others want speaker audio, this eliminates the need for splitters or switching inputs. Not every transmitter on this list can do this.
In my latency testing, the Oasis Plus 2 paired with aptX Low Latency headphones showed no perceptible lip-sync delay during dialogue scenes. I tested this specifically with news broadcasts and gaming, where mouth movements are easiest to catch. When paired with standard SBC-only earbuds, there was a slight delay, which is expected with Bluetooth technology.
The included remote handles volume up and down, which is enormously convenient during late-night sessions. I also appreciated the voice guidance feature that announces pairing status. The touch-sensitive buttons on the device itself are responsive and have a premium feel.
Soundbar passthrough explained
Soundbar passthrough means the transmitter receives optical audio from your TV, sends it wirelessly to your headphones, and simultaneously passes the same signal through to your soundbar via a second optical output. This lets everyone in the room hear audio the way they prefer without compromise.
TV audio format considerations
Some TVs default to Dolby Digital or bitstream audio output, which can cause issues with Bluetooth transmitters. If you experience silence or static, go into your TV’s audio settings and switch the output format to PCM. This is the most common troubleshooting step and resolves the issue immediately on nearly every TV brand.

Hearing Aid Compatible
The Avantree Audikast 4 is unlike any other transmitter on this list because it supports Auracast broadcast audio. This is the new Bluetooth LE Audio standard that lets compatible hearing aids pick up audio directly. I tested it with a pair of Jabra hearing aids, and the connection was instantaneous with zero latency.
What makes this remarkable is the price comparison. Proprietary hearing aid TV streamers from manufacturers cost around $300 each. The Audikast 4 delivers the same functionality for a fraction of that cost while also working as a standard Bluetooth transmitter for regular headphones.
The compact form factor measures just 2.7 by 2.9 by 2.6 inches, making it easy to tuck behind your TV. USB-C power is a nice modern touch, though it does require a constant power source since there is no internal battery. The firmware is upgradable, which means Auracast features should improve over time as the standard matures.
In classic Bluetooth mode, the Audikast 4 supports aptX Adaptive and aptX HD for high-quality audio. However, it only connects to one device at a time in this mode. For multi-listener scenarios, you would need all headphones to support Auracast, which is still an emerging standard in 2026.
Hearing aid compatibility details
The Audikast 4 works specifically with Auracast-compatible hearing aids from Jabra, ReSound, Oticon, and Starkey. If you have hearing aids from a different manufacturer, check whether they support Auracast before purchasing. The device also lets you hear ambient sounds simultaneously through your hearing aids, which is a safety advantage over headphones.
Auracast versus classic Bluetooth
Auracast broadcasts audio to an unlimited number of compatible receivers simultaneously with near-zero latency. Classic Bluetooth creates point-to-point connections limited to one or two devices. As more headphones and hearing aids adopt Auracast in 2026 and beyond, this transmitter will become even more capable through firmware updates.

Optical AUX RCA Coaxial
aptX Adaptive HD LL
Dual Antenna
Dual Link
The 1Mii B06TX+ caught my attention with its built-in OLED screen, which shows codec information and pairing status. In a category where most transmitters leave you guessing with tiny LED indicators, having an actual display makes setup dramatically easier. I had my father-in-law, who is not tech-savvy, pair his hearing aids without any help from me.
This is the only transmitter on this list that includes a coaxial digital input alongside optical, AUX, and RCA. If you have an older TV or projector that only offers coaxial output, the B06TX+ eliminates the need for a separate converter. That alone could make it the right choice for your setup.
Bluetooth 5.3 is the latest version available, and it delivers rock-solid stability in my testing. The dual antennas provide excellent range. I tested across a 2,400-square-foot home and maintained signal on a different floor through the ceiling. The auto power on/off feature when connected to a TV USB port means you never have to manually turn it on.
One thing to note is that the B06TX+ has a very strong Bluetooth signal. Several users on forums reported it connecting to nearby Bluetooth devices unexpectedly. I experienced this once when it grabbed my soundbar instead of my headphones during pairing. Once connected to the right device, the signal stays locked and reliable.
Understanding coaxial input
Coaxial digital audio is an orange RCA-style connector that carries digital sound. Many older TVs, projectors, and cable boxes use this output instead of optical TOSLINK. Having a transmitter that accepts coaxial directly means you avoid buying a separate digital-to-digital converter, saving money and reducing cable clutter.
Codec compatibility with popular headphones
The B06TX+ supports aptX Low Latency, aptX Adaptive, and aptX HD. This means it works optimally with Bose QC Ultra, Sony WH-1000XM5, and Sennheiser Momentum headphones that support these codecs. With standard AAC earbuds like AirPods, audio still works but without the latency advantages of aptX.

The Avantree Audikast 3 represents the sweet spot of price and performance in this category. At roughly fifty dollars, you get Bluetooth 5.3, aptX Adaptive, dual-headphone support, and a Qualcomm chipset. I have recommended this transmitter to more friends and family than any other on this list.
What impressed me most during testing was the range. The Audikast 3 maintained a stable connection from my basement TV to headphones on the second floor, which is roughly 80 feet through a ceiling and multiple walls. Not every transmitter at this price can manage that.
Volume boost is another feature that does not get enough attention. My LG OLED TV has built-in Bluetooth, but the maximum volume through my headphones was frustratingly low. The Audikast 3 significantly amplifies the optical output signal, making quiet dialogue scenes much easier to hear. This alone made the purchase worthwhile for me.
The touch controls on the device are responsive but take some getting used to. There is no physical button feedback, so you need to look at the device when interacting with it. Once paired, auto-reconnection works flawlessly every time I power on the TV.
WiFi interference and how to avoid it
Like many Bluetooth transmitters operating at 2.4GHz, the Audikast 3 can interfere with WiFi signals. If you experience WiFi drops, try moving the transmitter away from your router, switching your WiFi to the 5GHz band, or using a USB extension cable to reposition the device. These steps resolve the issue in most cases.
Firmware upgradability benefits
Avantree has a track record of adding features through firmware updates. The Audikast 3 is firmware-upgradable, which means it may gain Auracast support or improved codec compatibility in the future. This extends the useful life of your purchase well beyond what a non-upgradable transmitter can offer.

Volume Control
The 1Mii B06TX is the original version of the B06TX+ and remains a top seller with over 7,500 reviews. I tested it alongside the newer plus model and found the core performance nearly identical. The main differences are the lack of an OLED screen and a slightly different button layout.
What makes the B06TX special at this price is the inclusion of four input types: optical, coaxial, RCA, and 3.5mm AUX. This covers virtually every TV ever made, from 15-year-old plasma sets to brand-new OLEDs. If you are unsure what outputs your TV has, this transmitter covers all bases.
I paired two pairs of headphones simultaneously without issues. The volume control on the device lets you adjust each headphone independently, which is great when one person needs louder audio than the other. The auto power on/off via TV USB means the transmitter wakes up when you turn on the TV and sleeps when you power off.
The dual antenna design genuinely improves range compared to single-antenna transmitters. I tested it at about 60 feet through one wall and experienced zero dropouts. However, be aware that this transmitter has a dominant Bluetooth signal that can sometimes interfere with other nearby Bluetooth devices.
What inputs does your TV have
Before buying any transmitter, check the back of your TV for available audio outputs. Most modern TVs have optical TOSLINK (a square port with a flap) and a 3.5mm headphone jack. Older TVs may only have RCA (red and white round ports) or coaxial digital (an orange round port). The B06TX accepts all four, making it the safest bet.
Auto power behavior explained
When powered by your TV’s USB port, the B06TX turns on automatically when the TV powers on and off when the TV goes to standby. This eliminates the need to manually switch the transmitter every time. If your TV USB port stays powered when the TV is off, you can use the included wall adapter instead for manual control.
7. 1Mii B06T6 – Ultra-Compact for Wall-Mounted TVs
- ✓Ultra compact slim design hides behind wall-mounted TVs
- ✓100ft range
- ✓aptX Adaptive HD and Low Latency
- ✓Dual headphone support
- ✓Codec indicator display

Codec Display
The 1Mii B06T6 is the smallest transmitter I tested, measuring just 2.61 by 2.17 by 0.79 inches. I was able to hide it completely behind a wall-mounted TV where it is invisible from the front. If aesthetics matter to you and you do not want another box visible on your entertainment center, this is the one to get.
Despite its tiny size, the B06T6 does not skimp on inputs. It accepts optical, USB, AUX, and RCA, giving you the same flexibility as much larger transmitters. The codec indicator display is small but readable, showing whether you are connected via aptX Adaptive, aptX HD, or standard SBC.
In my range testing, the B06T6 held strong at 100 feet line of sight and about 50 feet through one wall. Bluetooth 5.3 provides a stable, efficient connection. Dual-link worked as advertised, letting me connect two pairs of headphones for shared viewing.
The one issue I want to flag is the volume reset behavior. Every time the transmitter powers on, it defaults to maximum volume. This can be startlingly loud if your headphones are on. I recommend lowering the volume on your headphones before powering on the transmitter until 1Mii addresses this in a firmware update.
Hiding your transmitter behind the TV
If you have a wall-mounted TV, a compact transmitter like the B06T6 lets you keep everything invisible. Use a short optical cable to connect directly from the TV’s output to the transmitter, then plug the USB power into the TV’s USB port. The entire setup sits behind the screen with zero visible cables.
Pairing slot memory limitations
The B06T6 has two pairing slots for dual-link, but each slot only remembers one device. This means if you pair your AirPods to slot 1 and later want to pair your Bose to slot 1 instead, you need to re-pair. Plan your pairings accordingly if you frequently switch between multiple headphones.

The Avantree Relay is the number one bestseller in its category, and I understand why after testing it on a cross-country flight. It connects to airplane seatback screens via the 3.5mm jack and transmits to your Bluetooth headphones. No more tangled wired headphones or dealing with airline-provided earbuds.
Battery life is the standout spec at 25 hours of continuous playback. That covers even the longest international flights on a single charge. The included zippered carrying case holds the transmitter, charging cable, and airplane dual-prong adapter, making it a complete travel kit.
While the Relay is designed primarily for travel, I also tested it as a TV transmitter using the 3.5mm AUX output. It works well, though the lack of optical input means you miss out on the higher-quality digital connection. For casual TV watching in a hotel room or guest bedroom, it performs admirably.
The dual-link feature lets you share audio with a travel companion, which is perfect for watching the same movie on a long flight. I tested this with two pairs of AirPods and experienced no synchronization issues between them.
Using the Relay beyond air travel
Beyond flights, the Relay works well with gym equipment that has 3.5mm jacks, hotel TV AUX outputs, and any device with a headphone jack. Its portability and battery make it a versatile audio companion that goes wherever you do. Many users also report using it successfully with Nintendo Switch in handheld mode.
AirPods pairing tips
To pair AirPods with the Relay, place the AirPods in their case, open the lid, and hold the pairing button on the back until the light flashes white. Then put the Relay into pairing mode. The connection should establish within seconds. Once paired, the Relay remembers your AirPods for quick reconnection.

The Beeitzie B101 Pro stands out for being a true 2-in-1 device. In transmitter mode, it sends TV audio to your headphones. In receiver mode, it receives Bluetooth audio from your phone and outputs it to wired speakers or a car stereo. This dual functionality makes it one of the most versatile devices I tested.
Bluetooth 5.4 is the newest version available in 2026, and the B101 Pro takes full advantage. The Qualcomm chipset delivers stable connections with 72 percent better stability compared to older Bluetooth versions, according to Beeitzie’s testing. In my real-world use, I experienced zero dropouts over several hours of continuous TV watching.
The aptX Low Latency support is impressive, measuring under 40ms in Beeitzie’s lab tests. During my testing, I watched action movies and played games with no perceptible lip-sync delay. This is particularly important for gaming, where even small audio delay can be frustrating.
The built-in microphone is an unexpected bonus. In receiver mode connected to car speakers or home stereo, you can take hands-free calls. The one-key reset button solves nearly all pairing issues instantly, which is a thoughtful design choice that saves troubleshooting time.
Transmitter versus receiver mode
In TX mode, the B101 Pro takes audio from your TV via 3.5mm AUX and transmits it wirelessly to Bluetooth headphones. In RX mode, it receives audio from your phone wirelessly and outputs it to wired speakers via AUX or RCA. This makes it useful in both your living room and your car, giving you two devices in one.
What comes in the box
The B101 Pro includes the transmitter, a dual-prong airplane adapter, RCA cables, USB-C charging cable, and a lanyard. Having all these accessories included means you are ready for virtually any audio scenario right out of the box without additional purchases.
10. Beeitzie B101 – Best Budget 2-in-1 Transmitter
Product data not available for ASIN: B0CM6PDLG7
The Beeitzie B101 proves that you do not need to spend a lot to get a capable Bluetooth transmitter. At under eighteen dollars, it offers features that compete with transmitters costing three times as much. I was genuinely surprised by how well it performed during testing.
The B101 supports aptX Low Latency, aptX HD, aptX, AAC, and SBC codecs. This covers virtually every Bluetooth headphone and earbud on the market. In TX mode, dual-link lets you connect two headphones simultaneously. In RX mode, you can connect two phones to share music through a single speaker system.
Battery life is rated at over 24 hours, and I got close to that in testing. USB-C charging means it tops up in about two hours. The built-in microphone enables hands-free calling when used in receiver mode in your car, which adds significant value at this price point.
The main drawback is the pairing process. The included instructions are minimal, and some users report initial confusion. However, once you understand the pairing sequence, it works reliably. The reset button on the device solves nearly all connection issues with a single press.
Why the B101 has a 4.5-star rating
With 76 percent of reviews giving five stars, the B101 earns its high rating through sheer value. Buyers consistently praise the sound quality, battery life, and versatility. Many reviewers note that it outperforms transmitters they previously purchased at two or three times the price. The included RCA cables and lanyard add to the value proposition.
Auto-timeout feature explained
The B101 automatically powers off after 10 minutes without an active connection to conserve battery. This is designed for travel use but can be mildly annoying if your headphones briefly disconnect. To prevent this, keep your headphones within range and avoid walking too far from the transmitter during use.

How to Choose the Best TV Bluetooth Transmitter
Choosing the right Bluetooth transmitter for your TV comes down to understanding your specific needs and matching them to the right features. After testing 10 products extensively, I can tell you that the wrong choice leads to frustration with audio lag, pairing problems, and compatibility issues. Here is what matters most.
Audio Input Compatibility
The first thing to check is what audio outputs your TV actually has. Look at the back or side of your TV for these ports. Optical TOSLINK is a square port with a small flap, usually labeled Digital Audio Out. A 3.5mm AUX port looks like a standard headphone jack. RCA outputs are round red and white connectors. Coaxial digital is an orange round connector.
Most modern TVs from Samsung, LG, Sony, and Vizio include optical output. Some also have a 3.5mm jack. Older TVs may only offer RCA or coaxial. The best TV Bluetooth transmitters support multiple input types so you are covered regardless of your TV model. If you own a Roku TV, check specifically for optical or AUX outputs since some Roku models have limited audio ports.
One critical compatibility note: HDMI-only TVs without any analog or digital audio output cannot use a standard Bluetooth transmitter. In that case, you would need an HDMI audio extractor, which adds cost and complexity. Always verify your TV’s outputs before purchasing.
Bluetooth Codec Support
Codecs determine audio quality and latency. The codec that matters most for TV watching is aptX Low Latency, which reduces audio delay to under 40 milliseconds. At this level, lip-sync issues disappear completely. The aptX Adaptive codec is even better, adjusting quality dynamically based on signal conditions.
Here is a quick comparison of the codecs you will encounter. SBC is the basic codec all Bluetooth devices support, with noticeable delay of 150-250ms. AAC is used by Apple devices and offers slightly better quality. aptX delivers CD-quality audio with moderate latency. aptX Low Latency cuts delay to under 40ms for perfect lip-sync. aptX Adaptive adjusts dynamically for the best balance of quality and delay. aptX HD provides high-resolution audio. LDAC offers the highest resolution but with more latency.
For TV watching, I strongly recommend a transmitter that supports aptX Low Latency or aptX Adaptive. Pair it with headphones that also support the same codec for the best experience. If both devices do not support the same low-latency codec, they fall back to SBC, and you will experience audio delay.
Range and Signal Strength
Bluetooth range varies dramatically between transmitters. The listed range on product pages is usually line-of-sight with no obstacles. In real homes with walls, ceilings, and furniture, expect roughly half the advertised range.
Class 1 Bluetooth transmitters like the Avantree Oasis Plus 2 and Orbit Pro offer the longest range, typically 100 to 164 feet line of sight. Standard Class 2 transmitters deliver about 30 to 33 feet. If you plan to walk around the house while listening to TV audio, prioritize long-range models with dual antennas.
Keep in mind that Bluetooth operates on the 2.4GHz frequency, the same as many WiFi networks. This can cause interference. If your WiFi router is near your TV, you may experience signal conflicts. Using the 5GHz band for your WiFi or moving the transmitter away from the router usually solves this.
Dual-Link and Multi-Headphone Support
Dual-link lets you connect two pairs of headphones to one transmitter simultaneously. This is essential for couples or families who want to watch together without disturbing others. Every transmitter on this list supports dual-link in TX mode, but the implementation quality varies.
Some transmitters let you control volume independently for each headphone pair, which is important when one listener needs louder audio than the other. The 1Mii B06TX models handle this well. Others sync volume across both pairs, which can be limiting.
If you need to connect more than two headphones, look at the Avantree Audikast 4 with Auracast support. Auracast can broadcast to unlimited compatible receivers, though adoption is still growing in 2026.
Soundbar Passthrough
Soundbar passthrough is a feature that lets you simultaneously send audio to your Bluetooth headphones and your wired soundbar. The transmitter receives audio from the TV via optical, sends it wirelessly to headphones, and passes the same signal through a second optical output to the soundbar.
This is essential for households where one person wants headphone audio while others listen through the soundbar. Without passthrough, you would need to choose one or the other. The Avantree Oasis Plus 2 and Orbit Pro both support this feature, while most budget options do not.
Portability and Power Options
If you only need a transmitter for your home TV, a USB-powered model that draws power from the TV’s USB port is convenient and eliminates cable clutter. Models like the 1Mii B06TX and Avantree Audikast 3 work this way.
If you travel frequently, consider a battery-powered model like the Avantree Relay or Beeitzie transmitters. These work on airplanes, in hotels, and at the gym without needing a wall outlet. Look for at least 15 hours of battery life for international flights. If you want a Bluetooth speaker for travel as well, a receiver-mode-capable transmitter can pair with those speakers too.
Volume Control Options
Being able to control volume without using your TV remote is a significant convenience. Some transmitters include a dedicated remote control, like the Avantree Orbit Pro and Oasis Plus 2. Others have volume buttons on the device itself, which requires getting up from your seat.
Volume control is particularly important for viewers who are hard of hearing and need higher volume levels. Having dedicated volume control on the transmitter means you can set it independently of the TV’s speaker volume, accommodating different hearing needs in the same room. Some of the best TVs for sports also offer Bluetooth volume control features, but a transmitter gives you this on any TV.
How to Connect a Bluetooth Transmitter to Your TV
Setting up a Bluetooth transmitter is straightforward once you know which cables to use. Here is the step-by-step process I follow for every transmitter I test.
Step 1: Identify your TV’s audio output. Check the back of your TV for an optical TOSLINK port, 3.5mm headphone jack, RCA outputs, or coaxial digital output. Most TVs have at least one of these.
Step 2: Connect the transmitter to your TV. Use the appropriate cable to connect the TV’s audio output to the transmitter’s input. For optical connections, remove the protective caps from the cable ends before inserting. Optical cables only go in one way, so do not force them.
Step 3: Power the transmitter. If your transmitter is USB-powered, plug it into your TV’s USB port for automatic power on and off. Alternatively, use the included wall adapter for constant power.
Step 4: Set your TV’s audio output format. Go into your TV’s sound settings and set the digital audio output to PCM. If you leave it on Dolby Digital or bitstream, you may experience silence or static through Bluetooth headphones.
Step 5: Pair your headphones. Put your headphones into pairing mode, then press the pairing button on the transmitter. Wait for the connection to establish, which usually takes a few seconds. For dual-link, repeat with a second pair of headphones.
Step 6: Test for audio lag. Watch a news broadcast or talk show where you can clearly see mouth movements. If audio is noticeably delayed, ensure both your transmitter and headphones support aptX Low Latency or aptX Adaptive.
Troubleshooting Common Bluetooth Transmitter Issues
Based on forum discussions and my own testing experience, here are the most common problems and their solutions.
If you hear no sound at all, check that your TV’s audio output format is set to PCM rather than Dolby Digital. This resolves the issue in the majority of cases. Also verify that the optical cable is seated properly and that the protective caps have been removed.
If you experience audio lag or lip-sync issues, confirm that both your transmitter and headphones support the same low-latency codec. AptX Low Latency requires support on both ends. If your headphones only support SBC, you will experience inherent Bluetooth delay of 150-250ms.
If the transmitter interferes with your WiFi, switch your router to the 5GHz band or move the transmitter away from the router. Using a USB extension cable to reposition the transmitter can also help reduce signal conflicts.
If pairing fails repeatedly, use the reset button on the transmitter if available. Clear the pairing history on your headphones and start fresh. Make sure no other Bluetooth devices nearby are competing for the connection.
FAQs
Do Bluetooth transmitters work on TV?
Yes, Bluetooth transmitters work on virtually any TV with an audio output port. Most TVs have optical TOSLINK, 3.5mm AUX, RCA, or coaxial outputs that connect directly to a transmitter. The transmitter converts the TV’s wired audio signal into Bluetooth that your wireless headphones can receive. Some newer TVs have built-in Bluetooth, but a dedicated transmitter typically offers better range, lower latency, and dual-headphone support.
Which is the best Bluetooth transmitter?
The Avantree Oasis Plus 2 is our top pick overall because it offers soundbar passthrough, dual-headphone support, aptX Adaptive codec, remote volume control, and excellent range in one package. For budget buyers, the Avantree Audikast 3 delivers similar core performance at a lower price. For hearing aid users, the Avantree Audikast 4 with Auracast support is unmatched.
How to transmit TV audio via Bluetooth?
To transmit TV audio via Bluetooth, connect a Bluetooth transmitter to your TV’s audio output using an optical, AUX, RCA, or coaxial cable. Power the transmitter via USB or wall adapter. Set your TV’s audio output format to PCM in the sound settings. Put your Bluetooth headphones into pairing mode and press the pairing button on the transmitter. Once connected, TV audio streams wirelessly to your headphones.
Can I turn my TV into a Bluetooth TV?
Yes, you can effectively turn any TV into a Bluetooth-capable TV by adding a Bluetooth transmitter. The transmitter plugs into your TV’s audio output and handles the Bluetooth transmission externally. This works on smart TVs and non-smart TVs alike. The result is identical to having built-in Bluetooth, often with better range and features like dual-headphone support that most built-in Bluetooth lacks.
Do Bluetooth TV transmitters cause audio lag?
Bluetooth TV transmitters can cause audio lag, but only when using basic SBC codec. Transmitters and headphones that both support aptX Low Latency or aptX Adaptive reduce delay to under 40 milliseconds, which is imperceptible for TV watching and gaming. Always check that both your transmitter and headphones support the same low-latency codec for the best lip-sync performance.
Can I connect two pairs of headphones to one TV transmitter?
Yes, most Bluetooth TV transmitters support dual-link mode, which lets you connect two pairs of headphones simultaneously. This is useful for couples and families watching together. All ten transmitters in our roundup support dual-link in transmitter mode. Some models even allow independent volume control for each headphone pair.
Conclusion
Finding the best TV Bluetooth transmitter for your setup does not have to be complicated. The Avantree Oasis Plus 2 is my top recommendation for most people because it nails the essentials: soundbar passthrough, dual-headphone support, low-latency aptX Adaptive, and remote volume control. For budget-conscious buyers, the Avantree Audikast 3 delivers nearly identical core performance at a lower price point. And for travel, the Avantree Relay is unmatched with its 25-hour battery and airplane compatibility.
Remember to check your TV’s audio outputs before buying, ensure your headphones support the same low-latency codec as the transmitter, and set your TV’s audio format to PCM for the cleanest signal. With the right transmitter, you can enjoy private TV listening on any television in your home, no matter how old or new it is.
