10 Best Bluetooth Audio Transmitters 2025 in the United States

The Avantree Audiplex is a versatile wireless audio transmitter designed to connect multiple devices to a single audio source, making it ideal for group listening scenarios like TV watching in family rooms, broadcasts in churches, or PA systems. One of its standout features is its ability to connect up to 100 receivers to one transmitter, far surpassing the typical dual pairing most Bluetooth transmitters offer. This is excellent for anyone needing to cater to large audiences or multiple listeners at once.

Additionally, the system supports AUX and optical jacks, ensuring broad compatibility with a variety of audio sources and devices. The use of 2.4GHz technology significantly reduces audio lag to just 30ms, which is notably better than standard Bluetooth and even aptX Low Latency, making it perfect for watching TV without the frustrating lip-sync delay. Each receiver also has individual volume controls, allowing personalized listening experiences without disturbing others.

The range is impressive, extending up to 100 feet, ensuring stable connections even in larger spaces. However, it should be noted that the device relies on battery power, which might be a downside for those who prefer plug-and-play convenience without worrying about battery life. Despite these minor drawbacks, the Avantree Audiplex offers a reliable, low-latency solution for multiple listeners, making it a solid choice for both personal and professional use.

The 1Mii Bluetooth 5.3 Transmitter is a solid choice for anyone looking to wirelessly send TV audio to one or two Bluetooth headphones or speakers. Its latest Bluetooth 5.3 technology ensures a stable connection with a good range of up to 100 feet, allowing you to move around without losing sound. The device supports aptX Low Latency and aptX HD codecs, which help reduce audio delay and deliver better-than-CD sound quality—ideal for watching movies or gaming where audio sync matters.

You can connect it easily to most TVs using optical, AUX, USB, or RCA inputs, making it compatible with the vast majority of TVs, though it does not support Dolby or DTS audio formats. One handy feature is the ability to pair two headphones simultaneously, though this causes the codec to downgrade to aptX (losing some low latency benefits). Volume controls on the transmitter add convenience, and a screen display aids pairing, which can be helpful for older users. However, it does not have a built-in battery and requires a wired power source, so portability is limited.

Users need to ensure their headphones are disconnected from other devices to pair properly, and some setup steps are required to avoid interference. This transmitter balances strong audio performance and flexibility with minor compromises, making it a practical solution for enhancing a non-Bluetooth TV with wireless audio capability.

The Sennheiser BTD 600 is a solid Bluetooth audio transmitter designed mainly for PC users who want to connect their Bluetooth headphones easily. It uses Bluetooth 5.2 and supports the latest aptX audio codecs, which means you can expect clear, high-quality sound whether you're listening to music, making calls, or watching videos. One standout feature is its low latency, helping to keep audio and video perfectly in sync, which is great for movies and gaming.

The dongle is very user-friendly with a plug-and-play setup and includes both USB-A and USB-C connectors, making it compatible with a wide range of desktops and laptops. It also allows you to use your headphone's built-in controls for managing calls and media, which adds convenience. Being a USB dongle, it requires a connected device for power, so there’s no battery to worry about, but this limits portable use.

This product is an excellent choice if you want a reliable, straightforward way to add high-quality Bluetooth audio to your PC without fuss.
