They looked like new out of the box, and it even smelled like coconut hahahahaha. Appart from that, they sound very good wired and via Bluetooth. The arch has been a bit uncomfortable at the beginning, but after some time I have grown used to it. The earpads, too, were a bit tight but again, I have grown used to it. However I don't think I can get a better deal than this, so I'm very happy with it
Looked like brand new. I'm very happy with the purchase, the sound is good, the battery life is excellent: I've been using them for several hours per day and on the third day after single charge they still had like 80% battery... Huge bang for your buck.
Alles wie beschrieben und erwartet. Die Kopfhörer waren absolut wie neu, in jeder Hinsicht. Der Sound super gut, Funktion einwandfrei und Haptik sehr wertig. Ich bin echt sehr zufrieden
Probé otros antes, me interesaba, aparte de la calidad del sonido, que es muy buena, la comodidad y la cancelación activa. Son todo lo que buscaba. Son estupendos.
I returned them because the ear cups was too small for my ears so it wasn't comfortable to wear.
