The Plantronics Discovery 925 is a Bluetooth earpiece featuring AudioIQ noise-cancelling technology for clear calls. The earpiece is operated via two buttons - one multifunction button for controlling calls and pairing the device and another for controlling the volume. The VFrame in-ear design of the Discovery 925 brings the microphone closer to the mouth for better call clarity. It can connect to two phones simultaneously to receive calls from both via multipoint technology and operates in a range of up to 33 feet. The earpiece comes with an earpiece case with a rechargeable battery that can be used to charge the earpiece on the go as well as 3 sizes of eartips.
