QC 35 mic fade in
So my Qc 35s have this issue where any kind of call request made while using my mobile device where the headphone mics are used as the Input causes a sudden loud static or buzz. The static fades down over the next several seconds. About 10 seconds to be precise. During these 10 seconds, the mic does it pick up my voice. But slowly gets louder from the 10th second at which point the listener can finally hear me.
This happens to WhatsApp calls, normal direct call, Google assistant queries made using the multifunction button,Google assistant queries made from the phone, WeChat audio recordings etc.
To give more information,I turned off the calls option in Bluetooth settings at which point I am unable to do any of the tasks mentioned above through the headphones, however recording on my inbuilt swing voice recorder still works. The same works without the previously mentioned static even when calls are enabled. Hence I made the assumption that only any kind of call Intent triggers the headohone mic to start off with static to fading in.
I have tried this on my android tablet and my windows pc. The same occured even when summoning cortana on windows and also with WhatsApp calls and Google assistant summons on the tablet.
I have tried almost everything to fix it, cleared my pairing list, used it with only one device connected, the soft reset thing where you disconnect,replug for 5 seconds etc. I have tried to be as detailed as possible with my query. Please, any help would be appreciated.
P.s I saw a similar thread by Eugibart, but no solution was mentioned on there
