Defunc TRUE (wireless) offers you a comfortable earbud with great sound quality, sleek Scandinavian minimalistic design which give you 60 h of playtime (3h x 20 re-charge). However it is so much battery power that we actually decided that it could be shared with your device, so we put a USB port so it could function as a Power bank – 2,100 mAh. If you don’t have power in your device = no music!
Charging time earbuds: 45 min.
Charging time Powerbank: 2,5 h.
