Ultrasone PRO-900 customer reviews
⭐⭐⭐⭐⭐ (5.0 out of 5 stars)
EDM Kings! I listen to mostly trap, and some other types of EDM and with a proper amp, these things really come to life. I have DT770’s 80ohm and the difference is night and day. These will literally vibrate your earlobes. They CAN run from a computer or phone, but the difference with a proper amp is remarkable; everything comes to life.
You’ll see people say “the bass hit in my beats is so awesome” and while any headphone can hit lower frequencies and make wubs in your ears, can they do it while maintaining the highs and not having the bass step all over the mids? I never realized what the audiophiles were on about, until I compared these side by side with Sennheiser 598’s, AudioTechnica M50x, DT770 80ohm, and a friends pair of Beats Pro Studio (or whatever they were called). If you have a pair of headphones and you are satisfied, that’s perfectly fine, but when you step into the realm of high end headphones, all the low and mid end ones you had before will sound like tin cans or sloppy bass cannons. I actually played the same song and would switch the headphones as it played, and the difference is astounding.
Unfortunately, I paid a lot more than these are listing for now, which is sad because it was an obvious money grab. I’m still happy though, and I’ve found the BEST HEADPHONES FOR EDM. Period.
Note: You’ll know when a track is low bitrate, it’ll make you want to claw your ears in disgust.

In this price-bracket it will be heard to get anything better from a closed-system

I’ve used the P900i on several Gear, always amplified in some sort for around 50 hours by now.
They really need a breakin & yet, I still feel they’re evolving….
Take this to heart not to judge if you receive them brand new… give them a good 50 hours as a first real indicator.
My main usage was on the PC for Music, Entertainment like Youtube, sometimes a little gaming –> That’s what i’ve bought them for.
You can wear this for longer time periods, they headphone isn’t heavy, it is a sturdy built with a veeery comfortable headband (P900i),
you get additional earcups, 2 cables (1/4 and 3,5mm).
Overall: Really good comfort and Value in terms of what you get in the box…
Mainly: (PC) Asus Xonar Phoebus –> P900
Others: Chord Mojo (DAC/AMP) –> P900
Oppo-HA1 (DAC/AMP) –> P900
(Not tested yet) Oppoa-Ha(DAC) –> WooAudio Wa22 (Amp) –> P900
I like the P900i, some say the bass is out of this world, too much… i don’t feel so actually…
Yes, this headphone has punch, it delivers, bass impact is top…
Mids are a tiny bit recessed sometimes, will see how they develop further down the road.
Highs are well defined, not too hot or too bright for my taste.
–> Those really seems to be a perfect fit if you listen to let’s say EDM – but at this time it isn’t the best allrounder.
In Terms of sound-stage i was pretty pleased from a closed headphone, S-Logic seems to do the trick here.
It does a really really remarkable job considered these are closed cans. You can separate Instruments on the stage easily, a nice size with good imagination.
Are there better closed cans?
Of course there are:
a) Based on YOUR personal preference, if you don’t like the sound signature of the P900 (which doesn’t make them bad, just not a fit for you ;-))
The best thing is always to listen with YOUR or comparable Gear… Because it’s not only the Headphone… If you talk audio, you’re talking about the whole Chain which start at the Source through all the things in between until you get to the Output (speakers/headphones).
b) If you’re looking into other price brackets.
I gave this Headphones a 5 out of 5 Stars, because in terms of Price/Performance Ratio it’s well deserved!
Grab ’em –> I’m very happy to have them in my Headphone Collection beside a lot of other headphones (HD800S, HD700, Grado GS1000E, Audeze LCD-3 among some IEM’s and even some Beats Models). I don’t think of swapping them out in the near feature, highly recommended.
For me this is a winner for sure!
An Amplifier is of course highly recommended even if they can be driven directly from a portable…. (A Fiio is a good start and won’t break your bank).

Highly recommended for the seasoned professional who isn’t concerned about being ‘cool’ and needs something they can rely on. If you are reading this, then you already know these are not ‘cheap’ headphones. They are also not ‘compact’ ‘trendy’ or very ‘stylish’. Here is what they are, for me at least. They are extremely comfortable, they ‘fit’ my extra large cranium, they are durable, they are reliable and they sound fantastic. Now, if you read this far, please take a moment to read the rest so you understand, at least from perspective, what I use them for. I own and operate a full time mobile music video service. I started (remember, full time = this is what I do for a living, no disrespect to the weekend warriors, however there is a difference for the person who only needs their headphones once in a while, not 6 out of 7 nights a week) my business in 1981, when you bought your headphones at Radio Shack, or if you could afford it, Lafayette Radio. Back then, just like today, my headphones were just like my wallet, something I had to have with me from the time I walked out the door until I came home. Unlike my wallet, that don’t break down, I also have set of back up headphones, just in case. For me, and any other serious VDJ or DJ, your headphones are part of your life. Now that I have established how important my headphones are, I move on to how comfortable they are, because for me, I ‘wear’ them. From the ‘first beat’, and until ‘thank you and good night’, my headphones are around my neck. The Ultrasone PRO 900 S are by far the most comfortable headphones that I have ever owned. And they are very durable, I have been using them (more about that later) since Winter 2015 without issue, and beside the visible scratches on the ‘shinny bits’ (that was for my friends ‘a crossed the pond’) I have had no problems. None, 0, zitch, nada. No problems. I liked them so much, I shopped around for some ‘like new’ pairs and have 3 pair in different locations so I don’t have to schlep them around with me, because, as mentioned they are quite large, and with the included case (and the case is a must as they include easy to use on the fly hot swap-able ear pads… in case you share them… or wear one out?) even though they ‘fold’ they still take up a lot real estate in my laptop / rolling work case, and having two pair with me at all times… yeah.. no. For my ‘on the fly’ back up / emergency / whoops headphones I use the Philips SHS3200BK/37 ear hooks, I will review them as time allows.
Now some important headphone history for me. What did I use before the Ultrasone PRO 900 S. As previously mentioned, when I first started, a mobile music service (aka a DJ) was a ‘new thing’ and headphones for this application were scarce. Most were either for the ‘audiophile’ who sat home and listened to “Dark Side Of The Moon” on Laser-disc… or the person who had to listen to their music because their parents didn’t want to hear it (see attached photo of me and my first headphones, yeah they were from Radio Shack) When I became a ‘professional’ and could afford a set of ‘real’ headphones, I went with what ‘everyone else’ was using at the time.. (remember “Play Misty For Me?” and WKRP..”) and for me that was the Sony MDR-V6 that served me well for a very long time. The ‘problem’ with the MDR-V6 is that the ear pads break down quickly, their durability as far as wiring goes is so so (and I take care of my stuff!) and they don’t have the ability to handle volume spikes over long periods of time. Now I want to add that used the MDR-V6 from the late 1980’s all the way until the early 2000’s so that says a lot for them. I think I went through a new pair of MDR-V6 every few years (of 3/6 nights per week). Around 2003, I finally had enough of replacing the MDR-V6 and decided to explore other options. I wanted something I could buy once and have for years to come. The first replacement was the Pioneer HDJ-2000-K. They were pretty good, but they feel apart just after the warranty ended, and Pioneer resisted helping me, however in the end they did, they actually replaced them, so when I had the chance, I sold them and moved on. The next headphones for me were the V-MODA Crossfade LP2 Special Edition Matte Black Metal They were available with ‘customizable’ ‘engraved’ Shields in Crimson Red. Reviews were great, so I pulled the trigger. When they arrived I fell in love immediately. Then I put them on… and was not impressed. I thought “well, let me break them in and see what happens’. I started using them 6 nights a week. After a month they got a little better, but they still were too small and not very comfortable. After a year I got used to them, but it was more of a ‘well they look cool, sound good, so deal with it and make it work’. 25 months into the relationship I went to put them on and the head band broke. The first thing I thought was… they have a 2 yr warranty. I reached out to them and was told “Unfortunately we wont be able to repair them, we can however offer you 50% off for a new pair if you like.” I was blown away. After some back and forth, I did get them to repaired, it just took a very long time. During that time… I had to find something else… so I bought the Ultrasone PRO 900 S, and I can safely say that so far, 16 months into using them everyday… they are fantastic and would recommend them to anyone with 1) A large head 2) needs something comfortable 3) need to use them in a professional setting. 4) need something they can reply on day in and day out. Oh and they sound great too. I only listen to them 30 seconds at a time, every 5 minutes, 4 hour shifts, 6 days a week, and at moderate levels. My neck is never soar, my ears are never ringing. I want to add that they have a nice isolation field as well. Put them on turn up the volume and you can tune out just about anything going on around you. I accidentally packed them (habit) and had them on a plane trip recently and the screaming baby next to me was only heard between the songs, so I put on a mix and took a nap. Oh, and what became of the custom V-MODA? I instructed my estate to have them around my neck when at my wake someday, and to be buried with them. What about the 3 pair of Ultrasone PRO 900 S? All left to up and coming DJ’s that I leave behind to keep the beats going.
In conclusion… if are not worried about style, or trends, and have the $$$ the Ultrasone PRO 900 S is a great headphone. At some point they will fail, and I will have to reach out to the manufacture for repair. When that happens I will update this review.
