BOROCO Helmet Headset - V4.1+EDR 500mAh

1. The external helmet of the host, compared with the built-in type (the battery is located on the earphone), the internal earphone is thinner, does not squeeze the ear more comfortably. 2. The host includes a larger capacity battery, up to 500 mAh, which increases the standby time and working time of the whole machine. 3. Fix the main unit with screws and buckle (built-in type usually uses glue or hookloop) to make the main unit install more tightly, and it is not easy to fall off when driving at high speed. 4. Using a powerful audio amplifier makes the audio volume range wider and does not affect playing and answering music in the noisy environment of high-speed driving. 5. Using high quality AMP chip can restore blue tooth audio with high sound quality. spec: Item Type:Helmet Headset Material: ABS Blue Tooth Version: V4.1+EDR CSR 8635 Frequency Range: 2.4026GHz-2.480GHZ Transmission Distance: approx. 10m/32.8ft (the transmission distance varies depending on environmental factors and mobile phone blue dental devices) MIC distance: ≤1meter/39.4in Lipo Battery: 3.7V/500MA Charging time: 4-5 hours Standby time: about 240 hours
