Boult Audio — Mic not working on my Boult X1 earphones

Address: Exotic Mile, 1st Floor, B-67, Wazirpur Industrial Area, New Delhi, Delhi 110052

The audio in my Bolt X1 earphones one day suddenly glitched, but after a moment the audio was audible clearly but when I attended a call the listener wasn't able to hear me but I was able to hear him perfectly . So I knew there is a problem in the earphones ( The warranty period is still not over, So I request to look over this problem.

Thank you,
