Disapointed with Ultrasone pro 900 midrange, suggestions on mods or other cans that are better?

post #1 of 12
Thread Starter 

So i recently purchased a pair of ultrasone pro 900s and at first I really liked them, but I've been having this nagging problem that the midrange is way to recessed and I'm thinking that maybe I should try a different set of cans now. I absolute love the detail in the pro 900s and the mid bass is great too, but the low bass (like very bottom) is too much for me and the high range on the pro 900s is too forward. I feel like the highs are very powerful, the very low bass is too powerful and the mids are just completely missing.

 

So i'm curious if the kees mod could help bring out the mid range, or if I should look into another set of can. I've read a lot of the reviews on here and the M50s sounds very good, as do the Shure SRH940sSennheiser HD25-1 II or maybe AKG K181DJ. Can you guys tell me how these will sound compared to the pro 900s? I'm worried about losing that strong mid bass form the ultrasone's and I'm worried about losing the massive detail form the ultrasone too, but the lack of midrange in the ultrasone is really bugging me, so I'm at a loss of what to do! I'm only looking a closed headphones fyi, I used them a lot around others and such and can't have the sound leakage from open sets. Any advice or suggestions? Thanks guys!

Are you amping them? The Pro 900's bass can be very boomy/uncontrolled with shrill highs that completely dominate the mids when they don't get enough juice. A good amp fixes these problems to a certain extent. When fully amped, the bass and treble are still more pronounced than the mids, but it sounds a lot more balanced and smooth. I really don't get why people say Pro 900 are easy to drive. They truly are unlistenable for me when unamped.

 

From the headphones you mentioned, I only compared the Pro 900 to the HD-25-1. The Sennheisers sound more neutral, so the mids are indeed more forward on those, but technically the HD25-1 isn't even remotely comparable to the Pro 900, so you need to look for something higher end to retain the same detail/imaging/speed that the Ultrasone offers.

 

The SRH940 could be a good alternative, but FWIR they don't have the same punch as the Ultrasone. I suggest getting an amp first if you haven't done so already. Then if you still don't like the Pro 900 amped, THEN look for other headphones. You need an amp anyway to get the best out of ANY high end headphone.

The Denon D7000 sounds like an Ultrasone PRO900 but with better mids. A bit recessed still, but much less so. It's overall a better headphone in almost all aspects IMO. People say the Pro 900 has more bass impact, but I don't think so. They are fairly comparable, except the Ultrasones have much more recessed mids and are grainier.

I am amping them with a fiiO E6.  I've read about the SRH940, and they could work but lots of people do say they lack that punch of the pro 900s, which I do like so I'm not sure if that is a good choice.  And while I would love a Denon D7000, that is way outside of my budget, the pro 900s were already pretty much the top of my budget.  What about something like the beyerdynamic DT660,770 or 880?  Those are closer to the pro 900 in price, would they be better on the mids but still in the same class as the 900s?

I've heard really good things about the J$ pads and how they brings the mids forward.

I have scene the reviews for the J$ pads but I'm hesitant to spend $70 on pads for a pair of headphones since I could still return these and try a different set instead of risking $70 to see if they help.  I'm more inclined to try the Kees mod since its cheap, easy and reversible and if that doesn't help I'll return these and try a different set of phones.  So I'm curious what headphones might be worth trying if I do return these headphones.

I owned the Pro 900 for a year,and enjoyed them immensely.  I too began looking elsewhere, however, and found the Denon D5000 to retain a lot of the bass qualities that make the Ultrasone great, but improving upon the mids and soundstage as well.

Why not try out that Kees mod like you said it does look easy http://www.head-fi.org/t/396267/how-bright-is-an-ultrasone-pro-900/60

 

How many hours on them?

I am going to try out the kees mod before I consider returning these ones yes.  And honestly, I don't know but i feel like the pro 900s just "popped", they suddently sound a lot better, not sure why though.   But I've got like 130 hours or so on them for burn in now, and I recently ordered a set of Denon D2000s, I'm going to do a head to head and see which I like since alot of people really like the D2000s (I would love to get the D5000s, but thats a little out of my reach).

I owned the D5000's, and upgraded to the D7000's.  The D7000's are in my opinion much more refined, but they ought to be for the price, even heavily discounted.  I had the chance to hear the D2000's a couple of times.  The D2000 is a better value than the D5000 in my opinion.  They sound almost the same, have the same driver and frame and pads, similar cable.  The real difference seems to be the cups.  If you really want woodies, stock D5000 cups come up for sale, and there is always Lawton.  I'll be interested to hear your comparison between the 900's and the D2000's.  I've considered the Pro 900's on occasion, just haven't tried them yet.
