How to use
Connect the 3.5 mm plug to the audio output of your player, smartphone or computer. Place the head-band over the top of your head so the supra-aural pads rest directly on your ears; adjust the position for comfortable contact and stable fit. For calls, use your device’s microphone and controls; for music and video playback, control volume and tracks from the connected device. Store the headphones in a dry place and avoid excessive bending of the cable to prolong service life.

To maintain optimal sound quality and extend the product lifetime, avoid exposing the headphones to moisture, extreme temperatures and prolonged direct sunlight. When using in noisy environments, increase device volume moderately rather than forcing the headphones beyond comfortable listening levels.
