From the Manufacturer:. NOISE ISOLATION: Quiet delivered to your desk.. Put on your Evolve2 40 and feel the noise around you instantly fade, as the isolating foam oval ear cushions and pioneering new angled earcup design work to effectively block out your surroundings, giving you outstanding passive noise‐cancellation.. Instant quiet without leaving your desk. That’s the new standard.. BUSYLIGHT: Don’t hide when you’re in your stride.. We’ve taken our busylight to a whole new level, making it visible from any direction. The red light is automatically activated when you’re on a call or in a meeting or you can activate it yourself at the touch of a button. So, even when you’re right in the middle of everything, your busylight will protect you from all angles, and all interruptions.. It’s like having a built‐in security guard for your concentration.. CALLS: You call the shots.. When you’ve got a lot to get through, seamless, professional calls are vital. So we took the incredible call performance of our world‐leading Evolve Series and we made it even better, building in three strategically placed powerful professional microphones and adding our advanced digital chipset and latest signal processing technology. So when you need to make the call, your headset won’t let you down.. MUSIC: Music matters.. We built this headset with powerful leak‐tolerant 40mm speakers and powered it with our most advanced digital chipset ever. The Evolve Series brought you great music while you worked. Now, with Evolve2, we’re levelling up the audio quality to bring you music like you’ve never heard.. Sound good? You bet it does.. COMFORT: The new standard of comfort.. We set out to create a wireless headset that would feel so great, you’d forget you were even wearing it. We designed the perfect shape using biometric measurements from hundreds of heads. Then we added soft memory foam cushions that mold to your ear’s natural contours. Finally, we assembled it using durable, premium materials.. We’ve taken comfort to a whole new level.
