I bought these for use with my Ipod touch in the Gym, the sound quality is very good, however they're a right devil to get to fit properly and what irritates most is the lack of grip on the inside of the bodies of the earpieces.
The reason being I've got a completely shaved (bald) head, so I have no hair for them to possibly stick to & so they tend to slip out a bit during exercise, especially so when I get sweaty on the cross trainer or treadmill, the result is the little grommets on the end which sit in the ear pop out and the volume + sound quality drops away; Which is a shame because if I listen to them elsewhere, then they're perfect.
What you will find in the packaging apart from obviously the headset is a small pouch with a charger with an EU & UK click in plug which you add to the adapter which has a MICRO USB B plug on it, now you if you have a phone like an HTC Desire, you can use your phone charger to charge the headset with, however you'll need some good finger nails or something with small point to open the small seal on the socket, which is located on the bottom of the Left ear pod.
With my set, the initial charge time was about 1hr, although I'd recommend leaving it around 3-4 hrs, possibly overnight if you've got the chance to give it a real deep charge, which I did and all is well on that front.
So all in all, I'm happy with the headset; However I've taken a star of for the lack of grip on baldies like me & another for the packaging being tricky to get into!
