What headphones do you use?

Panasonic RP-HTX7PP-W love the retro styling.

Audio Technia ADH-AD700. I'm on my second pair. They're grotesquely enormous, but you can barely notice them, even after hours of playing.

Grado 60 -- haven't used them much since I live by myself and usually listen to speakers.

Westone UM3x
UE TF10
Sony e888 (two pairs, love them for some reason)
audio technica.... aluminum earbuds. forgot what they're called.

Bose QC3 - Love the warm tones and the Noise Cancelling is second to none

a-JAYS Four - iPhone headphones with full mic and control. Great upgrade to the crappy white headphones.

Senheiser MX90s - Workout headphones. Good bass and nice and secure.

I also use a pair of Bose Aviation X for flying - good ANR and fits in my Cessna without any adaptors.

B&O A8. only really use them for travelling.

I have some Shure E2cs too but I lost the padding and haven't ordered any replacements.

Etymotic Research HF-5's.

Remolded Ultimate Ears Triple.Fi 10's

Sony MDR-V700.
Best cans I've ever owned.

For home use: Sennheiser HD600

I just replaced the outer foam covers ($50.00) after 10 years of wear and they feel like new again.

For work/gym/travel: Shure SE530

These are not as comfortable as the HD600 but still sound great and are more practical for on the go listening.

Grados SR-80's. Good sound on the cheap.

Shure SRH-840s. Love 'em. Wish they had a bit more bass, but they're so neutral that they make up for any lack of lower frequencies. Plus, I don't have an amp/DAC yet, either. I hear the bass tightens up and increases in punch with a good amp.

Just ordered some Senheiser 555. Apparently, if you remove a tiny piece of foam from the inside they sound just like the 595.
