How long will the charge in my headphones last?

The battery on your Audeara headphones will last for approximately:

30-35 hours with both Bluetooth and noise cancelling.

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

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

The Audeara headphones can also be used via the auxillary audio cable without Bluetooth/charge.
