The CC 520/540/550 headset
The CC 520/540/550 is a binaural headset with two
active earcups.
Via a telephone-specific adapter cable, you can connect
the headset to all standard telephones or Call Center
systems.
The headset is extremely comfortable to wear due to:
• ultra-lightweight design
• soft ear pad
• adjustable headband
• single-sided cable
• microphone that can be adjusted for left or right-hand
use
The specially developed “Active Anti-Shock” system
protects your ears from excessive volume. The micro-
phone’s “Ultra Noise Cancelling” technology effectively
filters out ambient noise.
If the headset is connected to a Sennheiser Communi-
cations Universal Interface (accessory), you can switch
between the handset and the headset and make use of
the many additional options offered.
