All the settings and features are actually great and I find the concept better than others I've tried. However, even after resetting several times, both sides would disconnect at random times and eventually only the left side connects on its own while the right side stays off.
I like this company's earbuds but each pair has issues. My old pair couldn't connect without the case. They fixed that issue with these new ones but they changed the charging from a regular USB male to a usb-c male. I need to buy a charger. It would have been great if it was a female then you could just use you phone charger. Still, overall I'm happy with the earbuds.
