Thank you for reaching out. That is unfortunate to hear what happened. I definitely want to help. Have you been able to test your headset across several devices? Just to see if the issue is consistent. Also, would you be able to perform a fresh reboot on the headset? I have the steps here below:
Turn the headset off and wait for 30 seconds.
Plug the headset into a USB power supply via USB cord and wait 5 seconds. (Power supply needs to be plugged into the wall with power on).
Unplug USB cord from headset and wait 1 minute.
Turn on the headset and test if the headset works properly.
If you are still not getting any audio, I recommend that you reach out to your local Bose Support and they will be able to discuss your exchange options.
