Hello Head-fi, its been a while. I decided to post here again after a long leave of absence simply because I have just had a very positive experience with V-Moda's support. My Crossfade2 Wireless Rose Gold developed a somewhat minor flaw (some creaking noises on one side) and V-Moda replaced...

I think it is. There is a lot of plastic used in the hinges and this has a tendancy to crack. Mine cracked a while ago and since they are no longer on warranty, it pretty much prevents me from using them anymore.

This doesn't sound like it has anything to do with impedance at all. Your cans have an impedance of 42 Ohms and the sound card should have no problem driving them. You can't 'burn out' headphones with an impedance mismatch, you could only perhaps damage them if you play them too loud. With this...

Just checking in to write how I solved the creaking hinges issue that these headphones have. I used a minuscule drop (and I mean tiny!!) of bicycle chain lubricant on the hinges. I carefully applied it using an ear-pick to the plastic in the hinges. The creaking is completely gone. If the...

Not sure if anyone discovered this yet but the Urbanears Zinken pads are quite a good option for the ATH-ES700. They only cost 5 USD and are MUCH plushier than the stock pads, its like having cushions on your ears. They also do not seem to affect the sound a whole lot, or at least I can't hear a...

I've always understood the term 'reference' to mean the same thing as 'monitor' but with the implication that the headphone is of very high quality (ie. a high-end monitor). 

They use the exact same drivers as the KSC75 so they sound pretty much just like them but a bit more open. Their weakness is in the enclosure as it is a cheap plastic that provides a fair amount of nasty ringing. I played around with my UR40 to dampen the enclosure (the plastic bits, I removed...

They look like a cheap pair of Audio Technica ATH-ESW9 but naturally, that does not say anything about how they might sound. 

  While they have different drivers, if we look at frequency response charts of the Amperior and the standard HD25, it is clear that they sound nearly identical. In other words, the 18ohm drivers are tuned to sound like the standard 70ohm drivers.    Based on your comparison, the Alu and the...

You could also try some pad rolling. I believe the pleather pads are less sibilant than the velour ones. There are also many after-market pads that you could try. I also believe the superbly comfortable pads from the Audio-Technica ATH-ESW9 fit the HD25, so that might be worth a try (I never...

I found that the KRK KNS 8400 has a very good soundstage for a closed headphone but it is one of those... strange soundstages. It is difficult to explain but appreciating the 8400 seems to depend on being able to 'forget' that you are listening to a headphone and just visualizing that the sound...

  Thanks! I'm looking forward to your findings.

There are many views on this... Some (myself included) strive for neutrality in audio gear, while others like for a headphone to be colored in a certain way that is pleasing to them. The basic fact of the matter is that a neutral headphone will be more versatile as it can work decently with any...

Mine don't have any such issues, so not all Amperiors are like that....

It won't hurt your headphone but it might hurt your ears if you listen too loud :)

Hmm, perhaps jfunk can write a followup for us regarding the pads on these two headphones. I have tried using some different pads with my Amperior for aesthetic customization purposes, but I have found that they changed the sound so dramatically that it was not worth it. I used some Zomo...

Have you tried switching the pads between the Alu and the Amperior? I'm wondering how much of the difference in the sound has to do with the pads. Leather/pleather pads are known to produce more authoritative bass on the same headphone than velour pads and velour tends to sound brighter, which...

Well, you should have a document confirming your purchase from the retailer, right? There should also be a date on this document. As long as the date is below 12 months in the past, you can send the headphone to the retailer or to Ultrasone for warranty service.

They most likely have at least 12 months warranty (depending on where you live - in the EU all electronic products have 24 months warranty) so it should be safe to return them to the shop to have them repaired under warranty. You could have indeed blown out the driver although it is more likely...

Yes, I've heard good things about the SIGNATURE line but the price seems like overkill for me :) I'm not really in the market for a closed headphone these days anyway as I am fully satisfied with my modified Amperior :)

Yes, as much as I applaud your call for research and using appropriate terminology, I do not personally require this lesson. The Pro900 seems not to be particularly sensitive but this just means that a 'modest' amp might not be able to make it play very loud. I personally don't care about this...

Would be possible if that figure was quoted by Ultrasone anywhere in their specs for the headphone, but it is not...   Sorry, the Pro900 is just too piercing for any kind of warm amp to make it sound nice. As for burn-in = sorry, it does not yield such huge improvements in sound (if any at...

lol, technically, being a 40ohm headphone, the Pro900 should not need a dedicated headphone amplifier to sound good... either way, I've tried them with all kinds of equipment and they always sounded terrible. the treble was so piercing, i still feel pain when i remember what they sounded like.
