Thanks, I was aware of those limitations. I intend to use it mainly for consuming media and possably as a remote for a naim streaming device in future.
I've got a pair of Goldrings which I use when flying long-haul. They work really well both with music from my phone and with the planes entertainment system. Don't know if they leak sound but who's going to notice on a plane anyway?
I got mine for about £50.00.
Just got HTC Sense 4.1 and Android 4.0.4 on my HTC One X. Cant really see any differnce. Perhaps battery life is better, but that has never been a problem for me.
You should contact the company you bought it from and inform them of their mistake. I'm sure if you had overpaid them in error you would want them to contact you about a refund.
