But not musicians (the latency makes it unusable), so the target market for extreme audio quality will be elsewhere, buying conventional analogue wired Audio-Technicas or Sennheisers; and not people exercising (they'll fall off your head), so the target market for that will be buying smaller earbuds.

I have a pair of AT's that happens to have Bluetooth and the only time I've used it is when mowing the lawn as a sort of ear protection with podcasts as a side benefit. Shitty audio quality would have been fine for this situation!

The market for this is the same thing as the market for a Gucci purse, basically, and that's fine, who cares; let it be for those people.
