Summary: Great phones. If you're short on cash, but can't get by with the cheap craps came with your MP3 player, then get these. If you're a fan of canal-phones, you'll more than likely love these.
Pros: They sound really great. I researched around and these are the best bang for your buck with the Shure E2C's being a distant, more expensive second. Not that expensive if quality is what you're after.
Cons: I don't like the cord, but that's just me. It tangles easily if you just put them in your pocket. I like the regular, both-cords-the-same-length scheme, but I guess Sony feels differently. My major gripe with these is that they're uncomfortable. I could wear them for a couple hours, but past that...
Summary: These are the first and only ear violating earbuds I have. They sound much better than stock headphones and beats most other in-ear headphones of the same price. I enjoyed them while they lasted although they did last for more than a year.
Pros: Awesome bass; Good looking design; Durable cord; secure silicone buds; comfortable; slim L-Shaped connector; gold plated connector; includes carrying case; great for on cord remote controls; great price for features
Cons: Earbuds themselves not so durable; sound not as premium as they could be; too long
