Neopon are TWS earbuds, albeit not ones of the typical 'popcorn' or 'stem' form-factor found everywhere these days.

Therefore, their maker asserts that they may enhance comfort and wearing time while still providing all the potential up-sides of wireless audio.

Laughable. It doesn't even address the issue of 3 irreplaceable batteries in one device.
