Poly Savi 8420 Office Stereo ANC DECT Wireless Headset

The Poly Savi 8420 Office is the stereo (two-ear) model in the Savi 8400 Office series, and the only model in the series with active noise canceling (ANC) — toggled on or off from a control on the headset itself. It shares the same color-display universal office base as the rest of the 8400 series, offering 3-way connectivity to a computer, desk phone and mobile phone, and a noise-cancelling microphone with close conversation limiting for clear calls.

A larger 700mAh battery (versus the 8410's 490mAh) supports up to 13 hours of talk time and up to 50 hours of standby, recharging in about 3 hours. Hearing protection is handled by SoundGuard DIGITAL, limiting sound levels above 118dBA with G616 anti-startle protection, and up to four headsets can be conferenced onto a single base for team training and huddles.
