London GB Music lover
Easy to link up - brilliant - We can both watch our own programmes one on the iPad and I have the TV to myself
It does not have a stand to dock it so it could remain charged up when not in use

Headphones don't fall of when bending down.
Uncomfortable after long amount of wearing them.They take far too long to recharge.

I thought they were ok when I first tried them .
Good long lead on them
Pity about the backround noise . After leaving them to charge for a good while didnt seem to have charged enough.
Bit too bulky and big.
