Earphone Bluetooth signal may occasionally be interrupted by other strong signals or under certain circumstances, such as when earphones are at a distance from mobile phone, in a multiple Bluetooth signal environment, in open spaces, under heavy rain, or in a strong wi-fi signal environment. We suggest staying away from radio interference (GPS, GPRS, wi-fi) and use Bluetooth version 3.0 or above for an optimal listening experience.
