Warm Tips:Sometimes earphones‘ signal might be interrupted,that is because Bluetooth earphones signal transmission is interfered by other strong signal. For example, when earphones keep far away from mobile phone,under the multi-Bluetooth environment, in the open place, under heavy rain environment, strong WIFI signal environment.We suggest you stay away from radio interference (GPS, GPRS, WIFI) and use bluetooth version above 3.0 to listen from the earphones better.
