The mix amp has to be always plugged in and you just charge the headphones using the USB on the back of the mix amp .
I received mine today also. How do you charge the mixamp tx unit? Is it via the large USB or the micro USB on the back of the tx unit? Thanks op btw
Paid £64 and received them today . The box had been opened but mine were actually new so very pleased. Thought I'd give them a try as I have the turtle beach 800 elites and the a50 seem so much better and louder .
Thxs OP Paid £67.94
Cheapest there is now is £159 (Not from Amazon), I think the deal should be expired now.
