How to use

Insert the 3.5 mm jack into the headphone port of your device until it clicks into place. Place each earbud gently into the ear canal for a comfortable fit and adjust cable routing to reduce strain. Control playback and calls using your device’s media and call controls. After use, wind the cable loosely to avoid tight knots and store the earphones in a pouch or case to protect the silicone cable and earbuds.

Usage recommendations

For best sound and durability, avoid pulling the cable to disconnect the earphones — grip the jack housing instead. Keep the silicone cable clean and dry, and avoid exposing the earphones to excessive moisture or high temperatures. If a secure fit is required during exercise, adjust the earbuds for a snug seal to improve passive noise isolation.
