I like a short charge time so this is great. I was blown away by the quality for this price range of a mic. They did this by sending me a headphone hanger. The QR code on the box, for supposedly verifying authenticity, is no longer useable at Sennheisers website. I had an issue with them once in the beginning where one side stopped playing and I had to find out how to reset them but then from then on they worked perfect since and they?re Bluetooth so buttons are sensitive and overall in the end you will figure them out and they work great! It will still allow wireless charging thru the case or you can access the charging port by opening a water proof "flap" on the bottom of the case. As others have said, it is hard to take the case off, but I think that is a good thing. It can be adjusted so that it fits well on my head (average male adult) and my sons head (average 10 yr old boy) too. I couldnt feel it as I was walking, so its not a big deal. I work outside and I do a lot of work outside around the house.
