Sogar besser als erwartet. Ich kann die Kopfhörer nur empfählen. Gute Audioqualität und Akku.
Un gran producto a un muy buen precio.
Ha llegado en perfectas condiciones, como nuevo. De momento sin ningún problema.
Muy feliz por esta compra. Una gran marc.
Great headphones for the refurbished price! ANC as well as natural noise isolation is great! Wonderful! Sound is a bit muffled or bass heavy to my taste, but the eq app helped out with that. These can get a bit uncomfortable though, if you have a big head like me. This is due to them squeezing a bit hard on my head, but without that squeeze there would ofc be more noise-bleed. Something to consider, but still a great product.
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
