FAQs & How-Tos

5 results
  • The ear pads can be removed and washed.
    To remove the ear pads, rotate them anti-clockwise to unlock (see image below).

    The ear pads must be hand washed only, do not machine wash - the water temperature used should be in the range specified below. Then wait for the ear pads to fully dry.

    Once fully dry, align the holes on the inside of the ear pads (highlighted with orange circles in the image below) with the clips on the headphones (located where the red arrows are pointing in the image below), now rotate the ear pad clockwise to lock the ear pads to the headphones again.

  • If you are experiencing issues getting the app to communicate with your headphones, (assuming you have already paired the headphones with the device) go into the communication apps audio settings. You will likely find the resolution there. You may have to set your headphones as the ‘communication device’ within the app you are using. 

  • • Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.

    • Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.

    • Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.

    • Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.

    • Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.

    • Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.
  • This product is rated IP67, which is different from IPX7. IP67 protects the product from submersion in 1 meter (3.3 feet) of water for up to 30 minutes. It is also resistant against dust. Dust accumulation around electronics can lead to hardware failure, so the IP67 rating is an extremely beneficial addition to this product. 
  • 1. First, try to restart the Bluetooth connection on your source device (Smartphone/tablet/PC) by switching Bluetooth off and on again with a short pause in between.

    2. "Forget" (remove) the previously paired connection (on your smartphone/tablet/PC) in your Bluetooth settings if you had once paired with your product.

    3. Try to restart the source device (Smartphone/tablet/PC) by powering it off and on again and after restarting, try to establish a Bluetooth connection to your product.

    4. If the above does not work, then try to restart your product (Portable speaker, Headphone) by turning it off and on again.

    5. Press and hold down the Bluetooth button on your device (Portable speaker, Headphones) to initiate pairing mode again.

    6. Go into the Bluetooth settings on your Smartphone/tablet or PC to start the pairing process.

    You should now have a successful pairing with your device. If you are still experiencing issues, please contact us again.
