With the Savi W440 USB Wireless Headset System from Plantronics you get both a convertible (over-the-ear, behind-the-head, over-the-head) headset and a charging base. The included cradle kit offers up to 7 hours of talk time reducing the need to constantly recharge the headset even on long phone calls. Setup and configuration is simple as this headset comes compatible with both Windows- and Mac-based computers. Once configured, you can take the conversation to distances up to 300 feet from the base. With DECT 6.0 technology, your connection remains safe and secure. Additionally, PC wideband audio up to 6,800 Hz ensures you receive enhanced audio performance. Users also benefit from enhanced hearing protection thanks to built-in SoundGuard Digital technology, which is designed to protect against sound levels above 118 dBA.
