QC 35 ii wil not power on, charge and no lights

Hello all,

 

My headphones simply stopped working this weekend after being left powered on fro 48 hours.

 

They will not charge, not power on and no LED lights up when plugged in.

When I put them on, there is an audible tapping sound, whether the power-switch is in the on or off position.

 

They work with the jack cable, but there is the tapping sound still in those cases.

 

I have tried rebooting (did not work) and I tried updating the firmware but the btu.bose.com website cannot recognize that the headphones are plugged in via USB.

 

Any advice?

UPDATE: I used it plugged in to my laptop with the audio cable for another 10 minutes and they just stopped working whilst plugged in. They no longer work using the audio cable, neither do they power up or charge. The tapping noise now has also stopped.
