How long will the charge in my Audeara A01 headphones last?

The battery on your Audeara A01 headphones will last for approximately:

30-35 hours with both bluetooth and noise cancelling (both switched on).

40 hours with bluetooth only (noise cancelling switched off). 

60 hours with noise cancelling only (no audio or bluetooth).

The A01 headphones can also be used via the auxillary audio cable without bluetooth/charge.
