The device charges when docked, only complaint is that it charges really slow but still it works better than occupying some extra space and a usb-c cable on my bedside table (dock sits on a separate table where I can see Alexas clock overnight). As being a current mechanical switch mouse user, this is the feel I prefer and enjoy with PC peripherals. I really wanted a pair of ?true wireless? head phones but NONE offer multipoint connection which for me is a must have. They are incredibly soft and inviting too. Slight movements might or might not make cuts in and out. The audio quality is pretty nice too. Mission completion. Dont quite get the logic of that! Which is why I recommend both. I am pretty disappointed by this product.
