How bright is an ultrasone pro 900? - Page 8

post #106 of 206
Can guess how freaked out I got about that with my new DAC and such lol.

I am using the official Kees mod. It was intact when I opened it . I applied it in the middle of the cup making sure it was as flat as possible. Also made sure the dampers was away from the driver.

I tried using the same diameter cotton as Kees (I think ~5.7cm) but I made it too thick and it was making me claustrophobic, so be careful not to go over 2mm thickness. I went back to unmodded afterwards and also so I can enjoy the burn-in process which is sure fun on Ultrasones. Later I'll buy the same exact felt as Kees and try again, I liked the effect the first time around.

Hi
Are these ultrasone 900's my best bet for music like electronic and drum&bass? Ty
I have DT770's now so I am looking for an upgrade.

Since no one is responding to you I'll try to give my impression of Pro 900's at 90 hours. I think the strongest point of these phones is neutrality and easily identifiable sounds, music enjoyment revolves around this and my attention is drawn to this fact whenever I listen to heavy songs where the music is intended to impact you with its cacophony and the Pro 900's keep all the sounds separate with high resolution. The Kees mod makes it have much more natural bass but I still prefer my HFI-2200's for music that's supposed to be noisy or music that doesn't require detail. I'd suggest you get the HFI-780's instead, although it is cheaper than the HFI-2200 it possesses newer technology and design.

Oh another good option would be to get opamps known for their smoothness to go with the Pro 900's while listening to heavy music.

@ Clok, sorry I kinda missed your post. What I like about the 900, especially contrary to headphones like 770 and 780's, is that they are very neutral and balanced. This might not give you the 'wow' effect the first time you hear them (though most who hear them, do get that effect), but they will not fatigue you. I have it when I listen to electronic music and I get tired after listening for 20mins, just because they decided that a heaphone should have boosted highs and lows. So, yeah, I would recommend them, I'm not fond of the 780 or 770's, only the recabled and modder 780's, but they cost twice as much.

What did you recable your Pro 900's with? I'm using a very smooth sounding blue dragon detachable which I feel doesn't go well with the Pro 900's at all which may account for my feeling that the Pro 900's doesn't have the umph for enjoying heavy music. But it sounds okay when I use very smooth opamp at the expense of detail lol.

A custom silver cable, very nice.

I am looking into doing this mod after I am done with my review, however, I do have a couple of questions about the mod. The white felt pad is that just a makeup pad or something else?

Also could I get you to take a new set of photos with the camera further away from the subject, the cause of your blurry pictures is because your lens cannot focus at a subject at such close distance (or the autofocus system misjudging the distance).

Thanks!

Hi, its indeed a make-up pad. I'm not gonna make pictures because then I'm gonna have to screw it all open again, dunno if Kees wants to do it either.

Two ingredients: the 5.5cm (or 5.7cm? just get the standard circle make-up pads lol) diameter cotton wool make-up pads, and then 2.5cm diameter 3mm thick oatmeal-colored felt pads. I am trying to find the proper thickness felt pads at stores atm, the cheap 3x 1mm stacked felt pads might be giving very different sound.

Kees told me he used HEMA brand, and he linked me an ebay link where I could buy it since it is not sold outside Netherlands. The link says it is 5mm thick, hmm. Must be the wrong one, I got 5mm ones and they are way too big, either the ebay seller has the thickness wrong or the link is wrong.
post #116 of 206
Hema is that the cotton wool? I need that link or some hint on what products to search for. I am thinking of trying a thicker layer of cotton wool again
post #117 of 206
Alright, thanks for the added info haloxt Will try and get some HEMA pads. The density difference between the pads will most likely affect the sound a lot. The makeup pads are easy enough to come by.
post #118 of 206
I found similar stuff on e-bay. I didn't get it there, but it can be an example for what you need. I never thought it would be this difficult to get this stuff. It is right there in every department store (HEMA for instance) in Holland.
The make-up pads and the felt stickers (they are stated 5 mm thick, that is including the sticky tape).

I'll see when I get time to redo the pictures.

No need to redo the pictures now I feel confident now that I have gotten some more info on it, thanks a bunch I will do some photos of my mod and upload them here when finished!

Great cans by the way, cannot wait to be done with the formal review and begin the modding process.
