better sound volume level than shokz open run 2, slightly louder than the aftershokz aeropex, but not as good sound quality when wearing ear plugs as shokz/aftershokz offerings.
sore to wear for more than a few hours. moveable speakers works well and helps cut outside noise. would be good if it opened a little wider.
difficult to find buttons even though the middle button is raised, would have been better if play pause was in a different location to the skip song buttons
charge speed and battery life are great. charger works ok, aftermarket adaptors can be finicky.
fast to connect to bluetooth.
