The best Bluetooth transmitter for your TV - 1mii B03
If you have an old TV or audio device at home and you want to make it wireless, then the 1mii B03 is a good choice. The B03 supports aptX low latency, multi-device pairing and receiver mode to eliminate lip-sync issues while watching TV. And it supports connecting two Bluetooth headsets at the same time.
If your wireless headphones lack aptX Low Latency support and you notice AV sync issues, you can try connecting the Bluetooth transmitter directly to your AV source device (if it has a 3.5 mm or optical audio output), which may cut down on some lag created when the signal has to pass through the TV’s audio processor.
The B03 doesn’t have built-in Dolby or DTS decoding, so you should change your TV’s sound output to the PCM setting when using it. If you don’t, you won’t be able to stream from services that offer Dolby Digital output, such as Netflix.
