Notes:
1.Please charge it fully before first use.
2.Locate and connect the bluetooth within 33 feets(10 meters) please.
3.Please think twice before you buy one if you have a very big head, for which we're very sorry, but we design the size of headsets according to the head size of Asians.Â
4.If you usually wear glasses, this type of bone conduction headphones may not suit you, because they both have to occupy the position above the ears.
Please read the user manual before using the headphone, and contact us anytime you have any questions. Thanks.
