How to use
Connect the 1.2 m cable to the audio output of your device and place the head-band so the ear cushions fully enclose your ears. Adjust the head-band for a secure but comfortable fit. For calls, ensure the device microphone settings are selected correctly if using an inline mic on the cable; otherwise use the device’s built-in microphone. To protect the headphones and maintain sound quality, avoid exposing them to moisture and store them in a dry place when not in use.
Usage recommendations
For the best listening experience during commuting and office work, set playback volume to a moderate level to preserve hearing and reduce battery drain on portable devices. When using for calls or online meetings, position the device microphone appropriately and choose a quiet environment to complement the headphones’ passive isolation.
