Philips SHE9500 Ultra Sound In Ear Headphones
About 15 bucks, but they sound pretty good. Has an extension wire though that broke pretty fast.
Sennheiser CX300-B Earbuds (Black)
Good noise isolation, pretty good bass, bit muddy on the mid tones. However, the sound from the wire rubbing is driving me crazy sometimes. Wire broke near the plug within a month (with moderate use, and I'm careful with my stuff). Now back at Sennheiser; expecting a replacement soon.
Sennheiser HD-212 Headphones (Silver)
Had these for a long time, they're still pretty good. They lack a certain 'warmth' but good enough to listen to music and watch movies with. Also very comfortable, even after hours of use.
A bunch of regular Apple earphones that came with iPods and iPhone. Sound like crap compared to most other earphones, but they have their use: they're good enough for some music while running and working out, and no need to be too careful with them.
