Bests & Worsts Reviews from Amazon

For this price, and with such quality claims, the product better be essentially perfect. It isn't close. Sound isolation and speaker quality -- what I hear when I wear these -- are good. The battery life is good, and they fit well in my ear, staying in place while moving. So if these were only for listening to music while working out, and not advertised as "we are great at audio calls with so many microphones and fancy tech", and not priced as the best things for music and calls, this would be a positive review. But they are sold as the best thing for calls, and they are priced accordingly. And the microphone quality -- how people hear me when I talk through these -- is awful. Lesser but still major problem: the activation force for the buttons is way too high. You either have to drive the earbuds deep into your head to get the buttons to click, or half-pull the earbud out to hold it with your fingers while pressing the button. And a nasty sw bug that should be fixable: every time bluetooth connects, a random few seconds later the headphones change to near-maximum volume. Usually after starting music, while trying to lower the volume. Ouch. Ouch ouch ouch.
