1) DT880 Pro 250Ω - Desktop only cans driven by either the LD MK IV or the E09K, these are the most comfortable headphones I own, excellent for everything but electronic IMHO.
2) Ultrasone HFI-780 (HM5 Pads) - EDM, DnB, Dubstep, Trance and anything electronic.
3) SOMiC EFi-82MT - An great all round headphone that I use quite often, a little more bass than the HFI-780's but has a real annoying plastic creaking noise while wearing them.
4) JVC HA-S500z - I take them everywhere I can either with the C3 or iPod, grocery shopping, coffee shops and malls... Stock all the way.
5) Koss Porta Pro - These are my take to work headphones, open so I can hear the phone or a co-worker needing assistance.
6) Monoprice 8323 (Headband & Velour Pads) - These would be up there in the number 3 spot for their sound, amazing for the price but the only problem with them is the way they sit squarely on your head. The wife laughs every time I wear them.
7) Koss TBSE1's ($29.95 on Clearout) - A really nice comfortable headphone that's all about the mid range, just not enough bass in them for me.
8) JVC HA-RX300H ($9 at XS Cargo one day) - These have a really bad muted sound and very uncomfortable, I use them as the sacrifice when testing new tubes in the LD in case of problems...
Well there you have it, sorry it's not much in the way of a sonic analysis but there are many, many reviews out there that can describe the sound of all the above headphones much better than I can. I factor some bit of functionality into headphones as well.
From what I read about the Takstar Pro 80's they will probably slide into my list in the 2 or 3 spot. A closed headphone with the beyerdynamic build style, so if it is anything like the DT880 it will be perfect.
Great 'phones (especially the 880's ! I envy you with that budget-oriented list
Would you say the Somics have more bass than the S500's? Is it basshead level ?
