It is £15+ on Amazon UK (pink) and if you go for blue/violet it is £7.40.
In stock. Google Shopping shows Play.com selling for £11+ but it is actually £4.99 once you're on the site.
This seems to have decent reviews and at this price, not a bad backup pair of headphones. Might make for a nice Christmas gift for a girl (if you shop this early!).
Hope it helps somebody! I bought one. I'll be away from the PC so feel free to add anything if needed (apologies for my ignorance).
