How to Pick the Best Bluetooth Audio Transmitters for TV
Maybe you’re trying to watch your favorite late-night TV show without disturbing your family. Or you simply want the convenience of a wireless audio setup in your home. In both cases, having a Bluetooth transmitter can help. So, what is a Bluetooth transmitter? That said, picking the right Bluetooth transmitter for your TV may not be as straightforward. First, not all TVs are the same. Some transmitters only support 3.5mm audio output, which may not be compatible with your TV. Then, there’s the issue of range too. You’ll need a transmitter with a suitable range that can adequately cover the distance between your wireless device and TV. Otherwise, you may get distorted sound signals instead of quality audio. To help make things easier, here is a list of all factors to consider before buying a Bluetooth transmitter for your TV:
Avantree Oasis Plus
Key features
Audio Output: RCA, AUX, Optical Transmission Mode: TX/RX Audio Codec: aptX, aptX LL, aptX HD Dual Link: Supports aptX LL Range: 164 ft / 50 m Bypass mode: Yes Bluetooth Version: 5.0 Additional Features: Touch-screen with Voice Prompt, Built-in volume control
The Avantree Oasis Plus is our best overall pick as it is jam-packed with features for a reasonable price point. It has support for both analog audio output (RCA and AUX) and digital audio output (TOSLINK). And, with a toggle of a switch, it can act as both the transmitter and receiver. Each TV has different types of audio output. Some offer both digital and analog audio output, while some only offer either one of them. Check that your Bluetooth transmitter caters to the correct type of audio connection. Otherwise, you might have to spend more money to purchase a converter for the connection to work. Below are the typical audio output that Bluetooth Transmitters support:
Digital Audio Output Optical Audio (TOSLINK) USB Analog Audio Output 3.5mm jack (AUX) RCA (red- and white-colored)
Depending on the Bluetooth version (latest version: Bluetooth 5.2) and class, the effective range can be anywhere from 10 m to 50 m. Measure how far you will be listening away from your Bluetooth Transmitter and consider the maximum effective range. However, a higher transmission range does mean that the Bluetooth transmitter has more power. This allows the signal to go through some wave interference before experiencing audio problems. This latency issue is also known as the lip-sync issue. This happens when the person on TV speaks, and you only hear the audio a few seconds later. This mismatch causes a jarring listening experience and/or makes a simple movie confusing. Audio codecs that you should look out for:
aptX aptX Low Latency (aptX-LL) aptX HD
Having the aptX codecs is basically equivalent to having HiFi Bluetooth audio. Other codecs encode a sound level for an audio file for each moment in time. Conversely, aptX codecs measure the differences in sound from one moment to the next and transmit them instead. This way, less data is encoded and has to be compressed and decompressed. Thus making aptX run faster and attain lower latency than other codecs. However, this will all be useless if your headphones do not support any of the 3 aptX codecs. As a general rule, your receiving device (headphones) must always support the codec of your transmitting device for proper transmission. If the codecs of your transmitting and receiving devices don’t match, then the lower and less advanced codec is used. For example, if your Bluetooth transmitter supports aptX, but your headphones only support SBC, it will use SBC. Of course, you will still hear the audio, but it wouldn’t be as good. However, it is possible that the same audio codec will not be used for both single and dual-use. For example, a Bluetooth transmitter can support aptX HD codec for a single connected device. But it may revert to SBC when there are two connected devices, depending on the model. Low-quality audio transmitters will require you to manually disconnect the headphones before you can use your built-in speakers or soundbar. However, some Bluetooth transmitters feature a “bypass” or “passthrough” mode to work around this problem. Bypass mode allows your audio connection to bypass the wireless connection and go through the wired speakers to play the audio out loud. Whereas passthrough mode allows wired and wireless connections to work simultaneously. This means you can hear sound both from Bluetooth headphones and your speakers. This feature is helpful if certain family members need to listen to the TV at a higher volume. Or also when you only have one optical output from the TV and it is currently being used by your AV receiver/speaker. This way, you don’t have to plug and unplug your transmitter all the time; rather you just switch between its modes. Some transmitters only have light indicators to reflect the type of codec you are currently using. Others use LED screens that clearly display the different types of codecs, transmission modes, etc. The transmitter’s look should also be considered before buying. Where are you putting it? Would it fit the theme and the aesthetic of that room? You wouldn’t want a large, bulky transmitter full of wires to destroy an otherwise minimalist space.
Transition modes
Some Bluetooth transmitters can switch modes from transmitter to receiver and vice versa. This is useful because you can send audio to a remote gadget using the transmitter mode, or receive and play audio from a remote gadget in receiver mode. This way, you can either use your device to enable Bluetooth connection in non-Bluetooth audio sources or allow audio to be received from your phone and played through wired headphones or speakers. With transmitter/receiver (TX/RX) combo models being available at the same price range as transmitter-only models, purchasing a TX/RX combo will undoubedly give you more bang for your buck.adapt
Built-in volume control
Another useful functionality is a built-in volume control on the Bluetooth transmitter. This makes it easier to adjust the volume directly on the device, instead of having to change it on the audio source itself. Such ease of accessibility is beneficial and is preferred by many people. In terms of audio codec, the Oasis Plus is one of the few rare Bluetooth transmitters on the list that offers up to aptX HD support. Even in Dual Link mode, it can maintain support for aptX Low Latency (aptX LL). Equipped with a Class 1 Bluetooth transceiver, the Oasis Plus can reach 164 ft or 50 m range in open spaces. Other than the usual Bypass Mode, the Oasis Plus also has the Passthrough Mode — a feature that only few transmitters can boast. It can share TV audio with an external speaker and a pair of wireless headphones at the same time. Lastly, the Oasis Plus comes with an elegant interface that displays the different modes and codecs you are using. And, unlike its previous model, the Oasis Basic, its interface is now touchscreen with a voice prompt option. However, the Oasis Plus may leave non-technical users scratching their heads as these require a few steps to set up and pair with your headphones. It’s also not recommended to use it with true wireless earbuds as doing so may introduce some audible sound delays. CHECK LATEST PRICE ON AMAZON
1Mii B03Pro+
Key features
Audio Output: AUX, RCA, Optical Transmission Mode: TX/RX Audio Codec: aptX HD, aptX LL, aptX, AAC and LDAC Dual Link: Supports aptX LL Range: 230 ft/ 70m (open-air) and up to 100 ft/30m (indoors) Bypass mode: Yes Bluetooth Version: 5.0 Additional Features: LCD screen display with Voice command via Alexa app
The slightly higher-priced 1Mii B03Pro+ is a strong runner-up with excellent features. Plus, it also offers one of the longer signal ranges on our list. The 1Mii B03Pro+ supports Qualcomm aptX HD, aptX Low Latency, and LDAC, giving you the best of both worlds. Both LDAC and AptX HD technology support higher bitrates and bit-depths compared to other codecs, allowing for better sound reproduction and less noise. These technologies have lower latency and provide better synchronisation between audio and visual, which is great for gaming or watching movies. With dual antennas, the 1Mii B03Pro+’s Class 1 Bluetooth technology can achieve an impressive range of 230ft or 70m in the open air. Combine that with its dual link feature, and you can simultaneously stream to two headphones or speakers. You no longer have to deal with the problem of blind pairing. With an LCD screen display, you can easily see and connect specific Bluetooth devices. Echo owners can also pair the 1Mii B03Pro+ on the Alexa app and effortlessly control the music using voice commands. In addition, the bypass function allows you to use your Bluetooth headphones and wired soundbar together without having to manually replug cables. Unfortunately, despite the seemingly high functionality, this still doesn’t support Dolby/DTS, which would’ve been great for home theatres. Instead, the 1Mii B03Pro+ only supports Stereo or PCM.

And while this may not be an issue, it does have some features to save battery that may sometimes backfire. For example, if no audio is played after a few minutes, it automatically goes to sleep mode. So you’ll have to constantly reach for the device and turn it on manually every time you want to restart listening. CHECK LATEST PRICE ON AMAZON

Avantree Audikast Plus
Key features
Audio Output: AUX, RCA, Optical, USB Transmission Mode: TX Audio Codec: aptX, aptx LL, FS, SBC Dual Link: Supports aptX LL Range: 100 ft/30 m Bypass mode: No Bluetooth Version: 5.0 Additional Features: Easy-to-hide design with built-in volume control function
The Avantree Audikast Plus is the transmitter for you if you’re mainly looking for something that would work amazingly with your AirPods. Of course, it delivers superior synchronized sound when you use other headphones with aptX LL tech. And it has dual link mode, so you can connect two compatible headphones at the same time. But what makes this great for True Wireless Earbuds (like AirPods) is its built-in volume control function, which specifically addresses one of the most common frustrations users have for AirPods (or other similar earbuds) — the lack of easily accessible volume controls. The Avantree Audikast Plus also has a cute and compact design. Its lack of antenna lets it take up less space and allows users to easily hide them away. But it has shortcomings, too. The most glaring ones (which could be deal-breakers to some) are that it doesn’t function as a receiver and does not sport the Bypass Mode. CHECK LATEST PRICE ON AMAZON
