‘M10’ is a folding concept Bluetooth headset.
General types of Bluetooth is not easy to handle (manage, keep) it’s headset in off condition.
This may come from the earphone part which comes up (to set the position on ear)
and this would be one of annoying point to manage in its off condition.
But the ‘M10’ eliminated this annoying by applying folding function.
In off condition this earphone part can be hided inside of main body, but in using condition it will come down in swing motion.
