Sounds good, but they are noisy for people around you

Summary: I owned 3 headphones from this price range - Beyer Dynamics DT900, Sennheiser HD-280 PRO and Ultrasone PRO 900. Sennheiser are "closed" headphones, you can listen to the music on high volume in public places without disturbing people around you. You can feel the bass, but it sounds not quite natural. Beyer Dynamics DT900 are "open" headphones, so no loud music in public. On small volume there is no bass at all, sound quality is good.
Summary: Loved these headphones so much I got another pair. Good sense of space and articulation of instruments in the mix I don't normally notice. Comfotable fit. Sealed so sound doesn't leak out where it bothers someone sitting close by.
Bloody great headphones, but not perfect. Really a 4.5 rating.

Summary: I'm an audiophile by my own discription and an alumnus of the Los Angeles Recording School for audio engineering. I'd been looking for a pair of over-ear headphones for some time now, as I usually listen to music with earbuds (Klipsch, Sony, ibeats by Dre which suck,etc.). After having a poor experience with the ibeats in ear and beats Solo headphones, I sold them and decided to look for another set. Between the Sennheiser Momentums and the Pro 900's, I chose the latter.
Summary: THE ONLY REASON WHY I GAVE IT A FOUR WAS BECAUSE ITS PRICE. WISH THERE WAS 4.5!!! The Ultrasone Pro 900 thought me a lesson that extreme bass doesn't always have to screw up other frequencies. While the high, beautiful sound of piano stays crisp, the base from the drum roars in my ears. In short, the base STAYS as base. It is true the mid are a bit recessed, but it is not to a level where it starts to get annoying.
Great through an AMP, but NOT through an iPod or Walkman

Summary: Amazing headphones! Great sound stage...and for people that want serious BASS...well there really is no other choice. However these headphones are hard to drive, they have an Impedance of 40 Ohm. What this means is you will need a separate AMP or Headphone AMP to drive them. If you are thinking of using them on a iPod, iPhone or similar...think again. The vast majority of portable players simply do not have the grunt to drive these headphones.
Summary: One of the best headphones for gaming and movies - superb for EDM and dubstep

Summary: Paired together with the iBasso D6, these sound phenomenal when playing Dubstep, Trance, House, Etc (Lossless) out of my laptop. They are relatively easy to drive, and will sound fine out of an iPod, but you don't know what they are "capable" of until you amp them from a good source. I still have wow moments when I play a new song, and I've already had them for 6 months.
Pros: Bass. Clear, tight, deep, penetrating bass. Zero distortion. Built like a tank.
Cons: Stock pads aren't the most comfortable. Very colored sound, not a good "all-around-er".
Summary: Good full sounding headphones. Sound is a little bottom heavy so if you don't like bass and like a more flat sound overall then I would steer clear of these. If you enjoy bass as I do you will be very happy with these. They also are a little weighty but still comfortable enough. The claim is that these are for pros who are using phones all day long.
