I like to listen to sentimental korean pop with female vocals. I didn't expect HD800 to perform this well, and with Anax mod, it's pretty damn good.

Currently having 2 HD800s with me, 1 my own and another my friend's which is on a long term loaner. S/N019XX for my friend's with thin cloth pads. As you guys have noted, these are bass light but I like them better since they seem a little more neutraish and the 6k resonance does not sound as bad.

Current pair I own is S/N14k~ they have more treble and also moar bass. A little more v-shaped than the older pair.

Shoot me, I will be using these to listen to jpop and watch cartoon porn.

Swapped the pads once and on brief listen, seems that the older pads do take out some of the treble of the HD800s and I do think the stage presented is different with the newer pads sounding wider than the old ones.

As for product variances, the 2 HD800s I have are virtually identical in sound with the newer one I THINK sounding to have slightly(~1db?) more 6khz than the older one.

Goldenears.net has retested HD 800(objectively and subjectively).

Very strange results. It seems as though the elevated treble and midrange resonance of the previously tested model gave the false impression of excellent transparency.
Apart from this, some people say that HD 800 is mild/soft(e.g. avguide review) while others find them very sharp and transparent.

Another goldenears fiasco...

That's the most mismatched HD800 I've ever seen.  And we've measured more than 10 units by now.  I'm going to chalk it up to user error based on his inconsistent results and subjective impressions.  I've also heard more than five HD650s and never have I heard them as being more 'transparent' than any HD800.  That's just absurd.  Probably what happens when he pairs the HD800 w/ his mysteriously unknown 'Goldenears' amp.  It's been well known from tons of impressions the HD800 will react with and display whatever is upstream more than any other phone.  His own inconsistent measurements and impressions point this discrepancy out.  Our consistent ones indicate it's not the headphone that's the problem.

Just so people know if they don't already, all the dynamic headphones measured on this site use my O2 amp.  Mostly to satiate the 'objective' crowd for a 'reference' amp (lol).

FR is accurate (I think).

Which?  The right or left channel?  Perhaps he forgot to check for hairs on the left side...
