[maruzen]

dt880 600 ohms
dt990 600 ohms
sennheiser ie8
 
 
but i get to use the sennheiser ie8 most of the time because i'm at work usually. however sound-wise, these are their rankings
 

 

[HyperNight]

Here's a list in order from BEST to NOT BEST: Paid under $200 category (Denon D2000 (189),  Sennheiser HD595($150, Don't sound quite as good as the ultrasone 580 but the comfort makes up for it ,Ultrasone Hfi 580(150), Dr. Dre Beats Pro ($400), Audio Technica M50 ($97), Beyerdynamic DT770 $140) (Almost have to have an amp if you like your music loud), Sennheiser HD555 ($100)  , Dr. Dre Beats Tour/koss porta pro
 
 
I was wondering why most lists don't mention the denon d2000? i thought they were the best around $200, the ultrasone hi580 at $150 price point, and the audio technica at $100. But I would like to know what headphones from Ultrasone, Audio Technica, and if anyone else has some punchy closed headphones. Thanks!

 

[tdockweiler]

Since someone else just bumped this thread (thanks!) I'll do my current list in order of best sounding headphones from best to worst:
 
AKG k601
Koss Pro DJ 100
AKG k240
Modded Koss UR-55 (grill removed)
Maxell DHP-II
Beyer Dynamic DT-235
Audio Technica ATH-M30
 
My overall favorite (not just based on sound quality) is the Koss Pro DJ 100. A $80 headphone shouldn't sound this good. Same can be said about the $30 DHP-II that impressed me from day one.
