Be Careful
1. For getting the enough volume to helmet headphone, the
maximum volume is higher than common Bluetooth headset.
Please be careful to adjust the volume when using a standard
earphone. It may damage your ears If the volume is too loud.
2. The strength of Bluetooth communication signal depends
on the connected device (cellphone or notebook). Place the
connected device and the product on the same side of the body
to get a good communication result. It is because the body
may block the Bluetooth signal.
