For more information, see www.nokia.com/support or your local Nokia website. This product may contain small parts. Keep them out of the reach of small children. The surface of this device does not contain nickel in the platings. The surface of this device contains stainless steel.
Bluetooth wireless technology
Bluetooth wireless technology allows you to connect compatible devices without cables. The headset and the <10m other device do not need to be in line of sight, but they should be within 10 metres (33 feet) of each other. The closer the headset and the other device are to each other, the better the performance. The optimal operating range is shown in dark grey in the picture. The connection is subject to interference from distance and obstructions (shown in light grey) or other electronic devices. The headset is compliant with the Bluetooth Specification 2.1 + EDR supporting the following profiles: Headset Profile 1.1, Hands-Free Profile (HFP) 1.5, Advanced Audio Distribution Profile (A2DP) 1.2, and 4

Audio Video Remote Control Profile 1.0. Check with the manufacturers of other devices to determine their compatibility with this device.
About active noise cancellation
Wolfson AudioPlusTM Ambient Noise Cancellation technology uses patented signal processing technology and advanced acoustic design expertise to deliver class-leading active noise cancellation for stereo headsets and headphones. This novel feed-forward technology cancels more decibels of noise across a wider frequency range than traditional feedback technologies, providing a peaceful and tranquil environment for users wherever they happen to be. As Wolfson's advanced technology does not process the playback audio stream, your music comes through in untouched hi-fi quality stereo.
