Advanced design, integrated technologies, and high quality materials enable the headset to provide you with clearer, more lifelike sound reception, while reducing unwanted noise. Wearing it comfortably and effectively Notice the marking L or R on the headband just above each earcup. They indicate the proper position (L for left ear, R for right) to ensure a good fit and performance. Put the headset on and adjust it so the headband rests gently on your head and the earcushions fit snugly (an effective seal) and comfortably around your ears (with your ears completely inside the ear cushions). Remove any jewelry or earwear that affects the comfort and fit of the headset. Using your headset The headset has two volume settings ­ Hi and Lo. These settings are only volume levels for listening to audio and do not impact the noise reduction technology. For noise reduction technology only, turn the unit on Hi or Lo and do not plug the headset into any audio source. For audio use, begin listening in the Lo setting. Then adjust the volume on the audio source. For more volume, try the Hi setting. First turn down the volume on the audio source, then switch to the Hi setting. Finally, re-adjust the volume on the audio source. The headset can be used with a variety of audio sources: CD, DVD, MP3, laptop computers, and home stereo.

It is best to avoid extreme volume when using this headset, especially for extended periods. Do not use the headset for reproducing sound when operating a motor vehicle on a public road or where the inability to hear outside sounds may present a danger to the user or others.
