Replacement Battery for Bang & Olufsen BeoPlay H7, BeoPlay H8, H7, H8

hi everybody today I'm doing a very quick video of what the free gift is that comes with the Bo play h6 or h8 headphones I'm sorry this is an unboxing but I have not got the box anymore because they kind of hastily threw it out in order to bring this home so here we have a cylindrical tube as you can see black bangle if seen written across the front here we have a microUSB and a regular USB port on top and nothing on the bottom so this is a battery so it comes with a cable that goes from regular USB to micro so you can plug in the micro into a standard wall outlet which will charge the battery and then plug any standard USB into here which will allow you to use this battery to charge either your phone or the headphones if you push down the bottom here this slight tube slides out revealing a battery and not much else I believe this means that you should be able to in theory replace your
