Very good if you can't have in-ear buds,
This review is from: Air Drives FIT INA9921 iPhone Earphones - Black (Electronics)In-ear buds give me headache so I started looking for something different and I found these. They're very good, sound quality is fine (but I'm not an exepert and I didn't test them thoroughly) but they really let you hear noises around you so don't get them if you want to block out people talking on the bus. It also means other people can hear your music if it's loud, so you might get told of (or get laughted at if a particularly bad song comes up on full volume).
They hang on your ear, which is fine, although after a whole day it feels like you've been wearing glasses too much and there's a slight discomfort. They're not the fastest thing to put on, especially if you have long hair in the way or big earings. I haven't tried any extreme sports but they tend to stay on the ear fine. The longer the tip of your ear, the better they stay on.
The volume control is useful and the pause/skip button works with iPhone most of the time, just have to make sure the plug is all the way in. Only thing I'd change is I'd put control panel closed to the earphones - it's half way down the cable and a bit too far to use the microphone for phone conversation.
