Wow.. just got these from DAHMART off of Amazon for $205 (refurbished but look brand new) and they sound amazingly well without an amp.  I've been using the HD25-1 ii for about a year and a half and my initial impressions of the Amperiors so far is that the sound is much more refined and cleaner...

Have you tried the dt1350? They are quite neutral and much more separation than the hd25-1.

yup skin oil, just wipe it after each use

I have both, I don't notice any improvements with them.     

Quote: yea same here, either I got use to the sound or it actually did change because I preferred my m-50's over the HD-25s, but now I like the Hd25's better.    

hd25-1's !! Even though I hated them at first : )

Make sure your ipod volume limit is not set too low and make sure your laptop system sound isn't lower than your headphone output sound setting.

what's your source?

Nice writeup, but I think you forgot to mention purchasing from an authorized dealer.

Quote: I think that is still sold third party. Looks like from "buy depot."

Quote: I'm at 50-60hrs. of usage and the clamping force does loosen after a while, you just got to keep wearing it or stick it on a box with your head width whenever not in use.  I hated them at first, but it does get tolerable with usage.  I probably wouldn't stick it over a heat source...

amazon has the coiled one for 125.00 right now (it's sold from another store but fulfilled by amazon so no worries). 

I actually prefer my m50's for listening to trance/electronica. I use my HD25's for mixing or for portable use. 

Yes the eq setting increases the lower end without disturbing the upper frequencies. I have mine on turned off though, I think it's perfect.

Go for the hd-25 if you dj and listen to trance. The hd-25's have tight/ punchy bass which makes beat matching precise, I also dj and noticed a lot of cleaner transitions in my mixes. The bass is non overwhelming so you can still hear your mids and highs. The isolation is also insanely good to...

Check out the shure 940. I had a chance to listen to them briefly at GC and the upper frequencies were very forward, clean, crisp, and sharp. The lower end was very lean and felt like extended bass as opposed to bass that is punchy.

Do you guys know if there's a substantial amount of SQ improvement from initial wearing?  I've put in 20-30hrs. so far in 2weeks and I'm not quite liking the sound.  It just seems a bit harsh sounding and not as detailed/seperated as I hoped for.    

Quote: Yes, I got mine today. Been using it with an iphone4 & ATH-M50 and the sound is much more crisper/fuller. I have my setting on Bass reducer in the iphone EQ + Hi/Hi & Eq 1 on the E11 for EDM and I'm loving it so far. I usually don't use the ip4 eq, but this setting seems to get...

^Hows the clamp? Did it loosen at all, mine after two weeks of purchasing are still hurting my ears.

Quote: It's just the bottom half that's coiled.

I have..you just stick the coil portion in you pocket.

I have the ATH-M50 and the HD25-1. Of the two I would recommend the HD25-1, the sound stage is smaller, but it is much punchier and right in your ear, the mids are pronounced as well. With the m50 the sound is much further from you and the mids being recessed make it even worse.  The HD25-1 fail...

Quote: No cutting or gluing involved. You just pull off the pads and the foam insert and put the DT250 pads on, there's not much more to it. I would keep looking for the DT250 velour pads because I felt the same way.   I think people are exaggerating the bass issue. I've painfully...

Jetsfool, you remove the stock pads and foam insert and replace them with the DT250's.  It literally takes about 5mins.  I highly recommend them because the stock pads (due to sweat) were intolerable/uncomfortable to me. The DT250 pads also fit like the stock ones and I honestly don't think it...

I replaced my stock pads with the DT250.  I think it still sounds amazing. The soundstage and bass widened, and the mids slightly increased. And it is much more comfortable as the stock pads made me ears sweat.
