Local Sony Centre were asking £64.99 for these. So at £17.99 they're a steal.
Easy to set up, can be listening to music within 2 mins of opening the box. I use them with a Sony Ericcson W610i and the remote controls on the ear pieces are very handy.
Handsfree: Everyone I've spoken to using them as a handsfree kit said it was like I was using the phone normally, very clear sound through the headphones.
Everyday useage they might not feel secure at first but I've been running and cycling with them on and they never once came off. They do take a little getting used to at first but once you've worn them a few times you feel comfortable.
Well worth the money.
