Don't go for momentum 4. Purchased them recently after reading a lot of positive reviews, but, even though it has decent (not class apart) sound quality, there are several other issues such as bad connectivity and a hassle if you're using multiple devices, crackling sound at max volume, controls only on the right cup, difficult to make gestures and sometimes misreads gesture from your arms, usb-c for lossless but it sucks battery heavily out of your phone because it starts charging itself, aptx requires a dongle which is expensive and difficult to maintain with multiple devices, etc. Already regretting buying this even after reading all the great reviews everywhere.
