The correct way to wear a motorcycle Bluetooth helmet should be: first grasp the pull ring of the helmet with both hands, and then wear it from the back to the front, that is, press it down from the occipital bone.

In this way, it is easy to enter or exit, and after wearing the helmet, the ears and face are more comfortable! 2、 Correct selection of motorcycle Bluetooth helmet size.

Then record the size and use this size to compare with the size chart of the helmet to choose the helmet suitable for your size! Usually, after wearing it, we have to move the helmet left and right first, and aim our ears at the auricle of the helmet. If the skull is not wearing a helmet, then this helmet is suitable for you! If the skull is too tight, the head will be very painful after wearing it for a long time!
