This product may contain small parts. Keep them out of the reach of
small children.
Note: 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
4
I n t r o d u c t i o n
Profile (HFP) 1.5, Advanced Audio Distribution Profile (A2DP) 1.2, and
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.
