Review on Avantree TC419 Bluetooth 5.0 Transmitter Receiver with Enhanced Range for TV & PC Audio, Home Stereo Speakers, aptX LL Wireless Adapter for Headphones, Optical & AUX RCA Connectivity by Steve Waldbillig

We use this with my new set of Avantree AS9PA headphones to watch TV. The transmitter supports Bluetooth 5.0 and aptx HD and LL codecs. It puts out very good sound and the range covers our two story house except for some dead spots caused by the furnace duct. Easy to set up and once the headphones were plugged in we didn't have to bother with Bluetooth connections at all. No weird stuttering when turning the headphones on and off. Aptx LL for the TV works, but when the TV speaker volume is high and you are using headphones it sounds like there is a slight echo. Since it's just the two of us, we only do this when one of us can't wear headphones (e.g. cooking dinner), so either turn off the headphones or deal with the audio. If the sound on the TV isn't too high, you won't even hear it through the headphones at a normal viewing distance. Please note that this is not a problem, just a note and applies to all low latency Bluetooth transmitters. Overall we are very happy with our AS9PA headphones and TC419 transmitter combo.
