The first one I got was damaged: scratchy sound and right side wasn't working at all. The replacement had both sides working but the sound was extremely scratchy (and I'm by no means a musically adept person). I couldn't watch videos on my tablet with them, that's how disturbing it was. I would not recomment at all.

Le son est mauvais : mon interlocuteur entend un sillememt aigu sans arrêt et ils ne sont pas confortables...
