Maybe you've got a bad pair or a hair stuck in the driver...

I will email Ultrasone right now.

Usually it does yes, as low end usually requires more power and excursion behind it (so yeah you can over-load the driver at 20khz, but its easier to do it at 20hz).

Good luck!

Really unless you're listening at hilarious volumes, something may be wrong, and the FiiO should be able to drive them with no problem. Are they new enough that you can still return them though? (If they are, and the dealer is good (e.g. Amazon) I'd just have them swapped that way, and save the time on doing a back-and-forth with a CSR).

I actually got them used, but have the receipt from amazon. Will I need to pay to get them serviced, even if I did not do anything to them?

Hi I just receive my mint PRO-900. It has now 15 hours play time on it. It sounds rather similar to my PRO-2900 to me. Maybe a little more bass and also a little more treble. But as I do not come from my sold Sennheiser HD 650 anymore, I can stand, no I lovebeyersmile.png the very clear high performance of these two Ultrasones. The ear pads of the 900 are slightly deeper than the 2900 pads, which is a plus for me. The pro logic presentation is also very similar to the 2900. For me it is just good to have two very similar cans for different occasions. Sometimes I need to be aware of whats going on around me and sometimes I must not disturb my surroundings. And always I have the best sound now. The PRO-550 is also a keeper for me, but the PRO-900 and PRO-2900 are more detailed for music listening.

Very likely you will have to pay - I don't think the Ultrasone warranty is transferable (assuming it's still even in effect). But it really depends on what Ultrasone says when you contact them - it's mostly at their discretion.

Well now I know to never buy used. Damn... I won't get an email back till January 2nd, as they are on their christmas break. What can be the problem?

That's just one risk of buying used - you basically assume the risk.

As far as what's wrong with them - tough to say, likely a driver defect or a manufacturing defect though. Probably nothing you can fix at home (but you might be able to at least see the issue - have you tried taking the pads off and looking at the drivers under a bright light? (I don't mean take the Mu Buffer apart)).

I did look at the drivers under a bright light, and they look fine. Is it maybe due to a low quality source and mediocre quality recordings (256 kbps)?

If the files themselves are distorting that will come through on the headphones - but you'd need another pair of headphones or speakers to test with to determine that. That said, 256k isn't really "mediocre quality" (it can actually sound great, depending on the material being encoded) - and by itself shouldn't cause such distortion.

What do you mean by a "low quality source"?

What I mean by a low quality source is for example an iPod, iPhone etc.

No those are fine quality - nothing at all wrong with them (they measure extremely well, and are well put together - don't let the "it has to cost as much as a new Lincoln to be tolerable" mythos get to you). They wouldn't be contributing to this either - unless you're clipping the input into the FiiO, but since you've said the issue exists without the FiiO, I'm guessing that probably isn't the case. I'd just try out the same files on something else and see if the distortion happens there, and wait to hear what Ultrasone has to say.

Oh okay. I just found out the weirdest thing... When I put the EQ to 0 on the E11, there is little to none distortion. When I use the bass boost, there is distortion. Can the bass boost be the problem?

Yes ;) So don't worry about your expensive PRO900 now ^^

 

I've had the E7, E10 and E17 before, and all bass boost were quite clean. What kind of songs were you listening to? I could imagine a bass heavy track + heavy bass boost + the most bassy headphone --> distortion...

I'm a new Ultrasone 750 Pro owner as of a week ago, and wanted to say hi to the other fans.  These forums helped me find a great deal on them and what to expect.  I also picked up an e17 to get better sound out of my laptop, that seemed a great choice as well.  I absolutely love the sound of the Ultrasone, sounded great out of the box and even better after about 25-30 hours.  I have turned the bass down to -2 on the e17, but I think that's more personal preference than a fault in the headphones.  I also don't have any of the distortion at high volume noted by another poster.
