FAQ for Bluetooth Headphones

QWhy my headphones cannot pair with my mobile phone?

1. Please check whether your headphone is in pairing mode or reconnect mode and check whether your mobile phone Bluetooth search function is opened; 2. Check your mobile device’s Bluetooth menu and delete/forget the headphones, then reconnect the headphones following the instructions on user manual.

QWhy my headphones won’t charge?

Please make sure both ends of the USB cable are securely connected. If you use a power outlet, ensure that the power supply is connected securely and the outlet works. If you use a computer, make sure it is connected and the USB port is powered. Turn on the headset and then turn them off. Disconnect and reconnect the USB charging cable.

QWhy do my headphone disconnect with mobile phone within 10 meter?

Please check if there is metal or any other material within relatively close range that may interfere with Bluetooth connection. Bluetooth is a radio technology that is sensitive to objects positioned between the headphone and the connected device.

QWhy is there no audio signal?

Check if the head phones are turned off. Check if the headphone are paired. If necessary, pair the headphones with the audio source again. Check the connection of your audio source. If the volume is too low, turn up the volume.

QWhy can’t I use my headphones to adjust the volume or select the track on the APP of my mobile phone?

App Software settings may vary according to some functions of the App itself not depending on the phone.

  • Works good, no problem

    From Joao Abreu Dec 26,2016

    It works good for the price. Easy to pair.

    It is a bit thick. If it was slimmer it would be perfect.
