I have tried various Bluetooth 5 solutions with Aptx LL without success, I confirm instead that these Sony WH L600 headphones are fine, the audio output from the mixer is more than good, no interruptions, pops, clicks etc., little hiss and background noise (very tolerable) and a minimal latency that I personally estimate between 5ms and maximum 25ms, which are absolutely not noticeable when playing. There is no radio interference of any kind although my house (building) is full of wireless of all kinds and there is no interference with the 5.8 gh wireless guitar (Ammoon AM 5Ghz) and not even with the Nux B5RC at 2 , 4 Ghz (the latter two are excellent among other things to get rid of the guitar cable, I have tried others but some had an increase in noise when playing).
While waiting for someone to produce certified very low latency headphones for guitar (no internal amp like Waza Air) this is an excellent system, I recommend it!
