Adding a New Bluetooth Device

Add a new device following the steps in 'FIRST-TIME SETUP'. The Flex Sport headphones can remember up to eight devices and will automatically connect to the last connected device. If you have paired multiple devices, turn off Bluetooth on devices you do not wish to use, and turn it on for the device you want to use.

Important Notes:

• Bluetooth is a short-range wireless technology, meaning objects between the headphones and the connected device can interfere with the connection. The headphones are designed for use with devices up to 10 meters (33 feet) away, without significant obstructions like walls.
• Once paired, the headphones will remember your device and automatically connect whenever you turn them on.
• Only one device can be connected at a time. To connect to a different device than the previous one, you must first disconnect the previous connection in that device's Bluetooth settings.
• If the Bluetooth connection is lost for any reason, manually re-establish the connection.

Warnings

• Try to prevent moisture or liquids from entering the earcups.
• Avoid extreme heat, cold, and moisture.
• Do not drop or crush the headphones. Do not strain the cord by pulling it quickly or forcefully, and do not bend the cord at sharp angles.
• Earwax may accumulate in the earcups, which can degrade sound quality. Carefully remove earwax with a cotton swab or another small tool to improve sound quality.
• If you feel discomfort or pain, try lowering the volume or stop using the headphones for a while.
• If you consistently feel discomfort when using this product, discontinue use and consult a doctor.
• We recommend treating your headphones like your favorite sunglasses and keeping them in a safe place when not in use.
