One of the first things I noticed is that the ear loop, which is also the battery, could be inserted into either side of the headset body. The ear loop makes use of the exact same connector as the charger does, and this is no coincidence. When you think about it, it makes sense. Both the charger and the ear loop/battery act as a power source. Plug either of them into the headset, and the headset has power. By setting things up this way, Epox allows the headset to be used as both a right and left ear device, and maintains a spot for the charger to connect, without the need for a separate attachment point.
