The head-band design distributes weight evenly for extended listening sessions, while the circumaural pads provide a degree of ambient noise reduction. The 1.2 m cable length offers a compromise between mobility and close-range device use.

Key specifications
 Frequency response: 15–25,000 Hz
 Ear coupling: circumaural (over-ear)
 Connectivity: wired 3.5 mm connector compatible with standard headphone jacks
 Cable length: 1.2 m
 Wearing style: head-band
 Colour: blue and white
How to use
Connect the 3.5 mm plug to the headphone jack of your source device and adjust the head-band so the ear cups sit comfortably around your ears. For clear voice calls, position the microphone-integrated cable (if present on the connected device) near your mouth according to the device instructions. Store the headphones on a stand or hang them by the head-band to avoid kinking the cable and to maintain pad shape.
Usage recommendations
Use at moderate volume levels to preserve hearing and extend driver lifespan. Avoid excessive bending of the 1.2 m cable near the connector; when unplugging, hold the plug rather than pulling the cable. Clean ear pads with a dry or slightly damp cloth and keep the headphones in a dry environment to prevent material degradation.
