The sound is very flat, what surprised me because I was used to bassy phones. Now I can't hear other phones anymore.
The sound quality is impressive and flat. You can hear everything, from the bass to the Bird singing. The quality of the phones are very good, it survived a washing machine once. The cable seems good at first, but within contact with the skin it seems to desintegrate the cables. It brakes in the middle of the plastic, then the copper wires inside brakes too and it's a pain.
The sound isolation is awesome, you can't hear anything from outside. It seems that the sound is inside your head. Just awesome. What makes the volume even higher because it doesn't need to compete with outside sound.
It's confortable too.
I would buy it again and recommend it, but buy a decent pair of cables to make the change.
