Oakley Meta HSTN mic issue? Everyone says I sound muffled on calls

Hey everyone, hoping someone here has run into this or has a fix.

I picked up a pair of Oakley Meta HSTN less than a month ago, and I’ve been having a consistent issue with call quality. I can hear people perfectly fine, but on every single call they tell me I sound muffled, distant, or just hard to understand.

It doesn’t seem to matter if I’m indoors, outdoors, or in a quiet environment.

So far I’ve:

•	Tried toggling the microphone adjustment setting on and off

•	Cleaned the microphones on the glasses

•	Tested on multiple calls/conditions

No improvement so far.

I use them with an iPhone 16Pro Max on latest iOS update and the meta ai app is also on the latest update.

Has anyone else experienced this? Is this a known issue, or does it sound like I might have a defective pair?

Appreciate any help 🙏
