Thinksound TS01 10mm (Black Chocolate)

Pros: unique and environmentally friendly design
very good noise isolation (I can't hear anything but music with these babies on)
open, natural sound
carrying pouch (made of recycled material!), cord clip included

Cons: unforgiving of poor-quality audio files
small earbuds; might not fit everyone, but I used the smallest earpieces they came with, and they fit me fine (three larger sizes are included)
mids and highs can be a bit bright at times; slight distortions

Summary: What attracted me about this pair of earphones was their slick and environmentally friendly design--they look even better in person, and there's no other way to describe it: the buds are just cute. I bought the black chocolate variety, but there's also a silver cherry finish. The buds are quite small, but the adapters that come with them should ensure most users a good fit. I have very small ears, and have to used the smallest earpieces with these guys; but three larger sizes are offered.
Sound quality is pretty impressive. I often forget that there's a world outside when I'm wearing these headphones; not only do they offer a lot of noise isolation, but the sound doesn't seem to come from the earpieces. Rather , it feels like the music is inside your head, or you're sitting in a soundproof room with a surround sound setup. The wooden housing does seem to contribute a lot to making the music sound natural and detailed. Deep drum-beats are especially impressive; you can feel them inside you. I would have like slightly more bass, but I wouldn't consider myself a bass addict; nor do I listen to especially bass-heavy music, which might have something to do with it.
I will say this: the headphones are super sensitive, meaning that if your music is poorly recorded, you'll be able to hear it in painful detail. But in general, music that I ripped from CDs sounded clear and very pleasant. The other unfortunate thing about these phones is that the portion of the Y cable connected to the earpieces (above the or divider, before the earpiece cables join) is sensitive as well--you can hear it if the cables rub against your clothes or hit your earrings, but it doesn't sound like static; it sounds more like a microphone when you tap it. I don't if that's a general feature of in-ear models, but I wouldn't recommend these headphones for gym use. Still, they're great for sitting at the computer or commuting. It's a minor gripe for a superb pair of earpieces, and I wouldn't have any problem recommending them, especially when they're so green!
