Brand new iphone 13 pro. Incoming calls—just phone calls—voices sound strange like in a tunnel. Is there a fix or should I return it?

Restart a couple of times.

• Restart your iPhone - Apple Support
• Force restart iPhone - Apple Support

Why the Issue?

• Interference: This is likely an error with interference. So, start here: If your AirPods Pro make crackling or static sounds - Apple Support
• If Used in a Closed Space: Does it sound muffled? If you are using these in a closed room, then echos can come about.
