Thank you very much for your message, welcome to the community!
I am so sorry to hear that your microphone is no longer functioning on your QuietComfort 35 headphones but I would love to get this issue resolved for you.
I would firstly recommend that you perform a reset of your headphones.
To reboot your headset:
Do you mind informing me what firmware version you are on so that I can confirm that this is the latest update? This can be checked within the product settings in the Bose Connect App.

Thank you very much for your update on this and performing a reboot of your headphones.
Does this issue occur when you connect your headphones to another device?
Also what service are you using to take calls? For example is this through any service like Skype or Whatsapp?
I would also ensure that your mobile device is not on mute during your call as this will effect the microphone functionality.
The issue is irrespective of the device I connect with (my phone and laptop) and the service I use to call (phone network, whatsapp etc).
The unanimous complaint I've heard from the people I call is that they feel that I am talking to them from 2 miles away - as if my sound is the smallest sound in the noise/echo of everything else - as if the microhone is working at 2% capacity.
So to avoid any confusion, I guess the microphone is 'working' for techincality's sake but not really of any use.
Thank you for confirming those details.
I would also recommend checking to openings on the microphones (shown below). Over the 2 years, debris and dirt may have built up.
Should clearing the mic ports not solve your issue, I would suggest that you contact your local Customer Service team.

I hope this helps, and if you have any questions, let me know and I'll be happy to help.

I have the same exact problem with my qc35 I microphone and have followed through all your steps and nothing solved the problem. The headphones are updated to the latest firmware, and a restarted the headphones the way you instructed. I went onto the Link in your message where it said I could only exchange my headphones for newer ones and will have to pay $259 which a huge price to pay for a ruined microphone. Is there not anything else you could do?
Thank you for you time
