They are great, especially for the price (even when not on sale). I paid $12 or so for mine a few years back. and they sounded fantastic for the price (though the sound signature took a bit of getting used to, that's a given for any new headphone).
Sadly IEMs are not for me, so I gave them away to a friend who is enjoying them greatly.
If you are looking for a good cheap IEM, or something cheap enough to not care about breaking, this is perfect.
