iPhone 13 Pro Bluetooth Mic Quality Terrible
I just picked up an iPhone 13 Pro, switching over from a Samsung S21 Ultra. When I'm connected to any bluetooth device, the audio quality of my voice through the mic is terrible. I use Whatsapp regularly and all my voice messages sounds muffled and tinny. I get the same sound quality issues using the iPhone's voice memo app. Using the Airpod Pros the quality is a little better, but nowhere near as clear as using the phone's mic.
I'm on iOS version 15.2.1. Music and voice messages I receive sound good, it's only the outgoing voice from me that has terrible audio quality. With the S21 Ultra, there was no noticeable difference in my voice quality while connected to any bluetooth device vs the phone's mic, all were clear and full.
