RECURRING USE
Once Flex Wireless Headphones have initially paired to your device, they will auto-connect to your Bluetooth device when powered back ON.
(Follow BUTTON FUNCTIONS instructions)
Notes:
• Bluetooth is a wireless radio technology, which means it is sensitive to objects between the headphone and the connected device.
The headphone is designed to be used within 33 feet (10 meters) of a connected device, with no major objects in between (walls, etc.).
• Once successfully connected, the headphone will memorize your device and automatically pair when turned on in the future.
Only one device may be connected at a time. To pair a different device, first unpair the current one through its Bluetooth settings.
• If for any reason Bluetooth connection is lost, manually reconnect your Bluetooth device.

WARM-UP YOUR HEADPHONES
Optional: Burn-in is the process for exercising new audio equipment. We recommend 40 hours of burn-in time for most headphones to reach
optimal performance. The main purpose of the process is to loosen the diaphragm of a newly crafted headphone and to stress the headphone
driver. Normal, everyday use can also burn-in the headphones though JLab’s proprietary burn-in provides an ideal mix of sounds and
frequency sweeps to achieve this.
Burn-in your audio equipment with the JLab Audio app available on the App Store and Google Play.
Or access the burn-in method at: jlabaudio.com/burnin
CAUTIONS
• Avoid getting moisture or liquids on the headphone cups.
• Avoid extreme heat, cold, and humidity.
• Avoid dropping or crushing headphones, stressing the cable by
rapid pulling or extreme force, or bending the cable at a sharp
angle.
• Wax may build up in headphone cups, lowering the sound quality.
Carefully remove the wax with a cotton swab or other small tool to
improve the sound quality.
• If you experience discomfort or pain, try lowering the volume
or discontinuing use temporarily.
• If you experience regular discomfort while using this product,
discontinue use and consult your physician.
• We recommend you treat your headphones as you would a nice
pair of sunglasses and keep them in safe location when not in use.
