Volkano 3 in 1 (smart watch, Headset and bluetooth speaker)

By “budget-friendly,” they seem to mean the cheapest equipment they could find. The headset is completely useless—it sounds like everything is being heard inside a tunnel, and the microphone doesn’t work at all since no one can hear you. It’s just terrible. I used it twice and tried changing the settings to improve it, but nothing helped.

As for the smar****ch, it works well, but the battery life leaves a lot to be desired. After a single bike ride or walking session, it needs to be charged again, as it won’t last another 2–4 hours without recharging.
