Key Features
Convertible DECT wireless design with three wearing styles (over-the-ear, over-the-head, behind-the-head) for personalized comfort throughout the workday.
Includes HL10 handset lifter enabling remote call answer/end by automatically lifting and replacing the desk phone handset.
Long-range DECT 6.0 wireless connectivity supports up to about 350–400 ft (up to 120 m) from the base for true office mobility.
Up to 7 hours talk time on a single charge, with adaptive power system that optimizes output to extend battery life.
Noise-canceling microphone reduces background noise so callers hear you clearly, even in open offices.
SoundGuard acoustic protection limits sudden audio spikes and keeps levels below approximately 118 dBA to help prevent acoustic shock.
Wideband and narrowband audio modes (approx. 20 Hz–6.8 kHz) let you balance HD voice quality with extended talk time.
Simple call controls on the headset—one-touch answer/end, volume up/down, mute—streamline handling of desk-phone calls.
