Ultrasone PRO 900

I've had this headphone 3 times.

I destroyed drivers in my first pair after 2-3 years of abuse. I ordered new drivers and then I broke the headband. Ultrasone was nice to give me a new pair in exchange for mine with the broken headband cuz they didn't have the parts.

I also ordered a pair for a friend that was hesitant to buy proper headphones after he was nice enough to lend me money when I needed it, gave him these as a christmas present.. He's very happy for them and friends agree those are amazing headphones for bass.

These headphones have put a huge smile on everyone I've tried them with.. I listen to music like drumnbass, psytrance and these headphones have never let me down and I've always struggled to find a pair that could trumph them.

The Pro 900 is special. It's the bass, which goes very deep, very low, and sounds powerful. This headphone also has some good impact, slamming nice and hard on electro house tracks. The bass goes deep, but it doesn't sound overly uncontrolled or boomy.

Okay, so it has great bass. What else?

These also have great detail. If you've never heard Ultrasones before, it's a safe bet you will hear things in your music you haven't heard before with their extended highs and very clear sound.

Now the mids. They are recessed. Even though this is true, it is obvious... If you're going to boost the low end and the high end, the middle part is going to sound less "boosted". The mids are still detailed, just not emphasized much in the overall sound signature. That's okay. You don't need very forward mids with EDM.

They are great with anything modern. Pop music, dance music, hip hop, anything with a modern beat which can take advantage of the bass of these headphones.

These are very comfortable. As the pads break in, they soften. The pad on top is very comfortable as well. I can wear them for hours with no problems at all. I actually love their design. Furthermore, these are built like tanks. You'd have to try really hard to damage these.

These have nice imaging when you get them positioned right. You can hear sounds from lower left, upper right, etc. It's a very interesting experience and something I have found the Ultrasones to excel at versus other brands I have tried.

I've had these for a couple of years now (although they don't get as much playing time anymore) so I figured I'd write a review.  Of all of the headphones I have owned these are the ones that wowed me the most upon my first listen.  The bass on these is just ridiculous.  They are easily driven by an iPod/Phone but do sound a good bit better when paired with a nice amp.  Like many others have said these do best with electronic music, or anything aggressive, however I have found that they perform more than adequately with all genres of music.  They are a very clean and sharp sounding headphone.  My main complaint about these would be comfort, they clamp very tightly and it can get uncomfortable after a while.
