After the A40/Mixamp combo...
You guys know all about my obsession with budget headphones which are too many to count so I wont post those:
AD700 ($75) - Sold to a friend. Loved them so much, but the loose fit and lack of headband irked me. Also my ears would get shocked by the drivers. I'm very static prone.
RE0 ($95) - Awesome iems. Sold on Head-fi. Didn't need high quality iems.
M50 ($92) - sold to roommate. Great at music. Bad soundstage for gaming.
Sony XB700 ($80) - Returned. AWESOME basshead cans, that were too boomy for gaming, and the stitching hurt my skin.
DT770 Pro 80 ($200) - sold on Head-fi. Great for immersive gaming, but too much muddy bass at times. I honestly didn't have problem with them but once I heard the K701, I couldn't stand the lack of clarity in these.
Tritton Ax Pros ($189) - returned and lost 15% of what I paid as a restocking fee. HATED IT.
DT880 32ohm ($289) - traded on Head-fi for used K701 (which was worth less NEW than my DT880s at the time, but I always wanted the K701. I didn't get them until then because I was afraid knowing that they were hard to drive, and Head-fi blows hard to drive headphones out of proportion. I'm sooo glad I got them. The 880s sound great but had a lack of positional cues for me. Too bad. I loved their sound more than the K701.)
K701 (look above) - Still own and will always own.
ES7 ($70) - Sold to a friend. Got them for music on the go. Fantastic, but uncomfortable.
Creative Aurvana Live ($65 on Newegg at the time. Went back up to over $100 until just recently) - Still own. Fantastic pair of closed headphones.
Turtle Beach PX21 ($80) - Returned. Hissing waaay too much.
Turtle Beach Z2 ($65) - first pair broke before I could test them. Second pair was returned. I didn't think these were anywhere near good enough for me.
DT990/600 ($229) - my saviors!
That's all in ONE YEAR.
So yeah, to say that the K701 and DT990 are all I could ever ask for, is saying a lot. There's absolutely nothing else I could ever want besides the DT770/600 for closed, and a mic I can use without attaching it to my headphones. Buying a headset would be pretty much useless for me as I voice chat like .00001% of the time I play games. I'm gonna order that cheap mic obazavil posted...
In no way do I recommend spending so much on headphones when ONE open (like a well balanced can like the DT880) and ONE closed would be the extreme amount of headphones a normal person should have.
