I have way tooo many headphones to list but I will tell y'all my favs.
Mdr-V6 (not 7506) have em over 20 years. still sound great
Denon AHD-750 Almost as old as my V6! Very simular sound but not as bright as the V6
Denon AHD-650 for portable quality sound from my ipod or Archos
Sennheiser 465 and 485 both sound great, one is larger than the other, most comfy cans except in the summer cuz my ears sweat.
MDR-V700DJ Yes, everyone hates em, yes, they break (on my second set) but these are for cranking bass and drum music to 11! These babys take a pounding and just dont blow out!
MDR-V900HD Yes, everyone hates these too but for stage monitoring and classical music these babies will let you hear every nuance.
I have many higher priced cans but the list above are the ones I use the most. I have around 20 different Sennheisers including the 5XX series and while they are all great in there ways I just dont use them that much. The Sennheiser 280 Pro, IMO, are the most overated POS I ever had. Dont know why they are a fav of a lot of people but to me they sound like crap and cannot take any decent amount of bass before they clip like mad.
One can I forgot to mention was the retro looking cans from panasonic. I forget the model # but they come in green , blue, black, and white. I bought them last year for the cool "retro" look and they are suprisingly great sounding for the price. I dont use em too much because they slide too much. My 2c
