These are terrible. Don't make the same mistake I did. Not only are they unflexible (so you have to fit your ears into them rather than fitting to your ears), not only is the sound quality terrible, but they also take forever to connect and regularly disconnect. I've never been able to use these for more than 15 minutes without having to go back and reconnect them (a process which takes up to 5 minutes at times). Usually I'm just a learn my lesson and stick with it type, but I'm binning these and buying something else.
