FAQ
1) Could earphones adjust the volume?
The earphones themselves cannot adjust the volume. Adjusting the volume of the devices( such as mobile phones, watches) that are connected with the earphones could raise/lower the earphones\' volume.

2) Could the earphones answer phone calls?
Only the main host earphone can answer phone calls, the other earphone cannot hear the sound from the calls.

3) How long could earphones generally last after a full charge?
After the earphones are fully charged, they could be used for about 2 hours.

4) Could the charge box and the earphones be charged at the same time?
Yes. they could be charged together. When the four indicator lights of the charging base shine blue, it indicates that the base is fully charged; when the earphones indicator light shines blue, it indicates that the earphones are fully charged.

5) How do I pair earphones with the mobile phone successfully?
Firstly, choose one earphone and turn it on by holding the button for 5 seconds until there and blue lights blink alternately. Then, turn on the Bluetooth on your phone and search for the device " Air50" and start to pair with the earphone. (You will hear voice prompt "connected" on the earphone after pairing successfully).
Last, turn on the other earphone by holding the button for 1 - 2 seconds (release the button as soon as you see blue lights). You can now you can start to enjoy the music on both.
(Please note that we must connect one earphone with the mobile phone before connecting the second)


Reminder: Sometimes the earphones\' signal might be interrupted due to the signal transmission interference by another strong signal. For example, when earphones are far away from the mobile phone, in an environment with other Bluetooth devices, in an open area, under heavy rain, or in a strong Wi-Fi signal location. We suggest you stay away from radio interference (GPS, GPRS, WIFI) and use a Bluetooth version above 3.0 to avoid these issues.
