I think the main problem is that Brainwavz is trying to do a very generic product, that fits every single headphone out there. I charge it once a week. I was actually afraid I was going to hurt myself at first because of the slipping and was going to return the shoes. Buying a couple more! I didnt feel any stones . Prior to updating the sound had screw scratching noises with the synth percussion, and that was not good. It easily clicks on and off when I need it to and it clicks around to make it convenient for me to look at my phone while Im working on my truck or when Im active. We did not, however, wind up using them for our most recent trip. I ordered this by mistake, I thought I was getting the moisturizer and I opened it sideways. Worthless if you bought this to chat with your friends on Xbox.
