Summary: The ear piece took some time to get used to. However, after a few days and experimenting with it a while, it was a comfortable fit. The microphone works well. The volume control is convenient.
Summary: You can't hear the noise, unless they are in your ear. i.e. other people won't hear your music. The buds have little angles to them, and it took me a while to realize that they go in the ear. It doesn't seem right at first, but then it makes sense. I would definitely get them again.
Summary: I've been using these for a while now and I have to say they're not bad. The rubber ear buds hasn't accidentally slipped off once. It is annoying that it doesn't feel like it's in your ear; it feels more like it's barely hanging on, but I got used to it.
Summary: These are the only earbud headphones I have ever used that stayed secure and in the same place throughout my runs and sweat--thus, no hassle and volume remains constant. Volume adjuster is also nice.
Summary: Just got these, so I can't comment on their durability. But: Sound is much better than OEM iPhone headset. What I can say with authority is that the instruction book is among the most inscrutable I've seen. The illustrations are particularly baffling.
Summary: I found these to be very comfortable, considering the inclusion of several different earbud sizes to fit a range of ear openings. The handy remote control on the cord makes it very easy to answer calls and to control your music at the touch of a button.
Summary: I purchased these because I had trouble finding ear buds that would stay in my ears while running or doing anything other than sitting still. I also wear them under hearing protection when mowing grass so over they ear types are uncomfortable.
