• Once successfully connected, the headphone will memorize your device and automatically pair when turned on in the future.

Warm-Up Your Headphones

Optional: Burn-in is the process for exercising new audio equipment. JLab Audio recommends 40 hours of burn-in time for most headphones to reach optimal performance. The purpose is to loosen the diaphragm of a newly crafted headphone and stress the headphone driver. Normal, everyday use can also burn-in the headphones, but JLab's proprietary burn-in provides an ideal mix of sounds and frequency sweeps.

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 wax with a cotton swab or other small tool to improve 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.
• Treat your headphones as you would a nice pair of sunglasses and keep them in a safe location when not in use.
