The earphones itself cannot adjust the volume, adjusting the volume of the devices(such as mobile phones, watches) that connected with the earphones could raise/lower the earphones’ volume.

Only the main host earphone can answer phone calls, the other earphone cannot hear the sound of the calls.

After the earphones are fully charged, they could be used 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 twinkle blue, it indicates that the base is fully charged; when the earphones indicator light twinkles blue, it indicates that the earphones are fully charged.

5.How to pair earphones with the mobile phone successfully?

Please note that we must connect one earphone to the mobile phone, then connect two earphones, please follow the following steps:

Firstly, Choose one earphone and turn it on by holding the button for 5 seconds until red blue lights twinkle alternately, after then turn on the Bluetooth on your phone and search, find the Bluetooth device ” Air50″ and start to pair with the earphone.(you will hear voice prompt”connected” on the earphone after pairing successfully).

Secondly, Turn on the other earphone by holding the button for 1-2 seconds (release the button as soon as you see blue lights ), By now you can start to enjoy the music on both.

Warm Tips: Sometimes earphones’ signal might be interrupted, that is because Bluetooth earphones signal transmission is interfered by another strong signal. For example, when earphones keep far away from the 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.
