Summary: This is actually my fourth pair of CX 280s, and it's not because the others have worn out. It's just because they're great. I own two sets, and keep one in my bag and one attached to an iPod. I've also given two sets as gifts. The bass is quite good for all types of music, including hip hop, and once you choose the right sized earpiece, they do a nice job of blocking out ambient noise (note that these are NOT active noise CANCELLING headphones).
Summary: These headphones work great and are reasonably priced. The earpieces are small & cushioned, unlike so many of the recent iPhone-style headphones, and so are very comfortable. The headphones also include 2 sets of alternative foam pads if you like a different shape for the earpiece. The carrying bag is nice, but not sure I'll really have a use for it. The cord is a little short for computer use, but works great for portable players. Overall, a very good purchase.
