Good solid weighty earphones that stay in place for stuff like cycling but have a tendency to bounce when jogging, so find something else for that passtime. No good for use at the gym because the standard trash pop they play at the gym finds its way past the earbuds into your ears, you'll need noise cancelling earphones for that. Sound quality is what's really important and they're about par with what comes with an ipod these days - makes the ipod useable but you'll wish you spent your money on something better. So, great for cycling (and we're advised not to listen to music while cycling, it's dangerous!) and rendered hopeless for any other sporty activity. What a waste of cash eh.
