Volume on the RayBan Wayfarer.

Love this glasses, but....

When I’m on a call, I find the volume to be very low. When I’m driving, I can’t talk through the glasses and have to switch to hands-free.

When I play music through the glasses, the volume is good, but not during calls.

Is anyone else experiencing the same problem?

For the record, the volume is set to maximum both on the glasses and on the phone.

Regards,
Mike
