whats the difference between a regular BT headset and a so-called TWS headset?is the latter any better?
Neckband style vs TWS basically - former has a physical connection between left & right earbuds, which helps in reducing cost over TWS as well as having a much bigger battery. TWS is truly wireless & has 2 free earbuds. Usually, neckband has 10+ hr battery life on a single charge vs 2-3hrs on TWS (case battery is different).
The old BT headset had just 1 earbud, so mono audio, just old tech at this point.
I use Oneplus Bullet Z, neckband style, because of better battery life & with TWS, I feel there's a higher chance of falling out of ear (I know its good, people exercise with it, but neckband is still better).
