With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
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.
