Pros below: Lightweight, comfortable (considering that I'm Lop-eared, I can sit in them for 4-5 hours without taking off), they hold a charge for a long time (for 12-14 hours it's definitely enough, no more saddles), it is possible to quickly switch from radio frequency to bluetooth, by yourself turn off if you have not used them for 30 minutes, there is no delay on the radio frequency, that's all I remembered Its cons: the microphone is not the best, but it will do, there is a loss of sound for 1 maximum 2 seconds, but this is rare, sometimes they don’t want to connect to the PC after switching from bluetooth, but this is solved by turning off the headphones, initially the arc from 1 ear to the other was more rounded, this is simply solved by that you wear them for a long time without taking them off
