    Marketing InformationHands-free productivity
    The CS540 convertible DECT™ headset provides professional performance so you can get more done - even on the move. The noise-canceling mic reduces background noise interruptions, ensuring great audio quality and easing listener fatigue.
    Give everyone more freedom to move
    Everyone in the office could use more flexibility. Let them roam confidently up to 400 ft from the headset base. They'll be able to collaborate simply since teams can conference up to four headsets on a single base.
    The choice is yours
    There's more than one way to make a call - switch up styles to find your groove and introduce your ears to something new. The CS540 convertible design comes with three wearing options: over-the-ear, over-thehead, behind-the-head.
    Features | It's just easy
    Simplify desk phone management with headset audio controls and adding either the HL10 Handset Lifter or Electronic Hook Switch Cable (EHC) for remote call capabilities.
    Extended range and talk time
    The adaptive power system optimizes for range and talk time by automatically downshifting to low power when the headset is close to the base - saving battery life and maintaining maximum density.
    SoundGuard technology
    SoundGuard acoustic limiting technology protects against Acoustic Shock by limiting sounds to below 118dBA ensuring listening comfort and protection against audio spikes.
    Superior audio quality
    Your choice of narrowband audio to extend talk time or advanced wideband audio for high - definition voice quality. Enhanced Digital Signal Processing (DSP) provides more natural sound, delivering clear audio the way it's intended to be heard.
    Maximum protection
    The CS540 headset includes DECT™ technology that provides better audio quality and eliminates interference from Wi-Fi networks while calls stay safe and secure.
