Have you considered possible interference and noise introduced by other rival devices competing for the same spectrum?

This has been my hypothesis, considering the disruption patterns I've noticed.

At home, well removed from other possible bluetooth sources, I rarely experience signal cut-out, or choppy reception.

When I move into high traffic areas, the amount of signal loss skyrockets. The worst areas are areas with lots of cars in motion.

My hunch, is that noise, destructive interference, and fortuitous signals result in dropped packets. And cars especially, tend to broadcast stronger signals that outshine an handset/headphone channel, cause both ends of the connection to drop packets.

This is just based on observation. In crowded train stations and near busy roadways my headphones act like shit. I get the feeling it's the old "poorly shielded blender appliance ruins the t.v. reception" business, except the interference drops out in the same way progressive scan HDMI monitors glitch up without shielding.

I have no proof that this is the case though.

hint: both are possible, simultaneously. one does not contradict the other. each one is a different concern, with its own merits.
