Great headphones, but with a software "feature"

Sound quality and ANC are good. Controls, features, and microphones are fine. But the inability to turn off the sidetone on windows is very irksome.

Awesome sound, like new condition

These sound fab! Buying refurbished was a great decision, they seem as if they were a return as when I turned them on they said ‘lost connection’ rather than pairing, but they have absolutely no damage on them whatsoever. The headphones sound great, and the ear cups are really soft so comfortable while wearing glasses. There is a very slight hiss when using the Bluetooth, but I seem to be very sensitive to this as no one else can hear it, but I can notice with all Bluetooth headphones - these are much quieter than others I’ve tried though, so I’m very happy with using them. If I’m somewhere totally silent and it bothers me, then I can just use the wire, so having this flexibility is really handy for me. Would really recommend!
