Communicate without distraction with the Evolve2 40 Stereo Wired On-Ear Headset from Jabra. In modern-day offices with open floor plans and busy work environments, noise and concentration are valuable commodities. Jabra crafted the Evolve2 40 headset to block out noise with isolating oval memory foam ear cushions and an angled earcup design to maximize passive noise isolation. 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.
