AUDIO PERFORMANCE
Dynamic EQ, microphone frequency response 100 Hz–8 kHz optimal for PC wideband voice telephony (up to 6,800 Hz), hi-fi stereo (C5220, C5220 USB-C only) receive frequency response from 20 Hz–20 kHz, enhanced Digital Signal Processing (DSP), noise- canceling microphone, adjustable audio alerts with Plantronics Hub software (mute/volume)*
HEARING PROTECTION
SoundGuard® DIGITAL protects against sound levels above 118dBA; Anti-startle (during calls) detects and eliminates any large sudden increase in signal level; Time-Weighted Average prevents average daily noise exposure from exceeding 85 dBA (enabled by Plantronics Hub). Additional lower level hearing protection against acoustic startle is provided by Plantronics Hub software limiting peak levels to 102 dBA
