Communicate without distraction or wires with the Evolve2 65 Mono Wireless On-Ear Headset from Jabra. Utilizing wireless Bluetooth technology and an included USB Type-A adapter, you can take important calls at your desk or walking the halls. To stay focused, Jabra incorporates an isolating oval memory foam ear cushion and an angled earcup design to maximize passive noise isolation. A call can come at any time, which is why Jabra integrated a powerful battery that gives you up to 37 hours of power. A convenient charging stand lets you recharge between calls and songs. To keep people at bay, the integrated red busylight can be seen from any direction and is automatically activated when on a call or in a meeting. It can also be manually activated when needed via earcup controls. Three strategically placed microphones and an integrated digital chipset for signal processing work together to help ensure that your voice and call quality sound professional during important calls. This specific headset is UC-certified to provide seamless integration with all leading Unified Communications platforms, such as Cisco, Alcatel-Lucent, Avaya, and more. When not working, the 40mm driver delivers high-quality, leak-resistant audio playback for your favorite music or podcasts.
