I bought these having had a set of earbuds (Ultimate Ears Triple Fi 10s that cost approx 200). The earbuds had an awesome sound and great isolation, but over the years it became tedious having to fiddle with getting them into and out of my ears to talk to people in work.

I wanted to keep the sound quality and isolation, but lose the inconvenience. These earphones delivered on all fronts. The sound is a lot better than the earbuds for the following reasons:

* The soundstage is surprisingly wide for a closed earphone. It's a little less wide than my open cup Grado SR80s, but you certainly couldn't use them in an office environment as everyone would hear your music; overall, the Grado's sound is eclipsed by these anyway

* The bass is powerful, which works very well for the music I listen to (ordered by the amount of time I spend, the main genres are: jazz, dance/electronica, alternative rock, pop and a little classical). The bass is well balanced and, to my ears, it never overpowers or dominates, but I can relate to why some reviews say the headphones sound a little warm

* There is more/better tonal range as these headphones are extremely detailed. This means you hear everything that's in the source music - if your source is not very clean, it'll probably be a pain to listen to - I have some old jazz recordings from the 1950s and 60s and these headphones expose every flaw. However, the upside is that for clean recordings, done at good bitrates, the headphones connect you with the texture of the music in such a way that you can, for example, almost feel the resonance of bass notes.

The Ultasone PRO 900s are a fantastic set of headphones. Whilst initially it takes getting used to the sound stage which is very different from "normal" headphones once you are used it it enables mixing in a very different and far more accurate environment virtually akin to my studio's Adam nearfield monitors. They are also sufficiently light weight not to cause too much fatigue on the head when wearing for extended periods of time.
The only downside is I had expected a hard cover carrying case - the case whilst rigid isn't quite what I expected but still sufficient for transportation purposes.

Highly recommended.

When i recieved the package without unboxing it,i was quite suprised by how heavy the box is.
The headphone is acturally pretty light, what make it heavy is the carrying case.
Talking about how it sounds, to be hounest when I first listen to it, it doesn't sounds as how i have expected it would be.Probably it takes time to burn in.The depth of the music is really aupricing , and also the bass is so tight and strong.But what I dislkie about this headphone is that the vocal is too sharp which makes you feel kind of irretated.But I guess this will improve after 100hrs of burning in.
Overall i'll say in this price range this is really a must buy.(This Cost like £380 in my country)

Right, where to start, I'll start with what I was impressed by; the build quality is fantastic, then again I kinda knew it would be from a German company, they're solid as a rock, if like me you were only used to DJ headphones before, then be prepared for a nice surprise, now my DJ headphones seem so flimsy and weak in comparison, but suitable for what they are designed for. You can wear these for hours and your head doesn't feel compressed and uncomfortable like with a lot of headphones, which is great for long sessions, although they are quite chunky it feels like your head is in a booth, obviously the closed back design of this version add a lot to that. They come with a nice well compartmentalised case, which is easy to store on a shelf or whatever when you arent using it. 2 sets of ear pads, 2 cables, one straight one coiled.

The important part is the sound, as with all my headphones before I do anything with them I run a frequency sweep through them for about 2 hours to wear them in, I was impressed with the frequency range over all but now I'll move on to the cons.

They are great for in the studio but unless you are really really experienced don't try to gauge how things are going to sound for other people on other systems, while using these headphones because you really need to listen to all your music through them and realise just how bass happy they are, to the point where is almost ridiculous. The bottom end doesn't distort and sounds nice and warm but they are just so bottom end oriented and it really swamps the mids. All frequencies on their own sound great and if you listen to a really high quality audio file then you can get away with it, but for a fairly amateur producer, trying to get an early mix down sorted to move over to another system is pointless.

I just bought these, and I have to say that I was confused at first when I got them. I had no idea how to plug in the cord to the headphones, so I searched for the headphones on youtube and found a great video on how to plug in the cord.

As soon as I started to listen, I was amazed by the depth of the music. I noticed the difference between these and my old headphones right away. I heard parts that I had never heard before, from music I had listened to for years!
The bass is the best part, and some people say that the bass is too much, but I have to disagree and say that it is just right.

But I guess for all, their own. And this one is truely mine :)

(Sorry if I didn't give enough feedback on these, but I am no expert on the subject. I just got these, and they sound better and better everytime I listen to them).
