Review on 1Mii Wireless Bluetooth 5.0 Audio Transmitter with Low Latency for Nintendo Switch & Lite - APTX LL Support for Headphones, Speakers, PS4, PC - Includes USB C to A Converter by Ashley Davis

Seems to work very well for me though, easy to link. However, it does NOT work on PS3 and doesn't work on my TV yet. It works at least with the switch and (redundantly) with my laptop. It's good to have a small storage bag so it doesn't get lost
