I’m not a bluetooth absolutist, but I think is depends on the bluetooth transmitter in your phone (or laptop or other).
My phone, a 7 year old low end phone has multiple times better signal strength than the only dongle I could find for my PC. That fast forward like things is also the quirk of a specific bt adapter, I think, or maybe the OS, but I haven’t noticed such a thing to happen, even though I have experienced too audio drops from me being too far away.
I’ve had multiple phones and tried two bluetooth headsets but the fast forward and bad signal happened with all of them. I’ve experienced bad signal with the phone in my pocket too. Also had it happen on a plane multiple times which forced me to switch to cable. WiFi has never had these kinds of problems, but bluetooth consistently has.
