NOT usb C really annoying cant use other usb B cables to charge it. My biggest complaint is that, out of the box, the strap is extremely rough on the toes. You can save the planet sure in fact charge me more and I will plant some trees but don’t swap the plastic sticks to paper. Very very good quality. It works so long as I keep my phone on me, and in my pocket. Pros:- good battery life- fairly good sound- pairs with anything without issues and keeps connection- lightweight- an extra 12 months of warranty when registering onlineCons:- uncomfortable to wear for longer periods- a lot of cable noise when moving around- couldnt get it fit into my ears no matter what I triedAfter a few days I decided to return it and look for something else thats more comfortable to wear without the cable noise. consigliatissimi. I was happy enough with the first one to have bought the same thing again. I should’ve read the reviews. Well I was screwing in one of the bolts, the head of the bolt broke off.
