I had one of these before and the one I had previously seemed to blow a lot more air out but this one still works great.

Disappointed
The sound quality is great. Only problem is it took a month to come in and once it came in, one of the senheiser logos fell off. It has been a week since I've had these headphones and the sound in one ear has gone out. It does come with a one year warranty so I'll see if I can use that.
