Lightspeed Aviation's passion for performance and value is reflected in every Lightspeed headset. Each headset comes with a long list of advanced innovations: Finely tuned ANR - Streaming Quiet™ ANR has firmly established Lightspeed as the leader in noise reduction technology, but every Lightspeed headset incorporates finely tuned ANR for exceptional quieting. Engineered for Comfort- All Lightspeed headsets feature comfort-designed headbands as well as plush ear seals with larger openings, 20% more surface area, and up to 50% more space for your ear inside the ear cup than our closest competitor. The result is superior distribution of weight and side pressure for maximum comfort, even on long flights. Full Bluetooth® Integration - Every Lightspeed headset delivers excellent wireless call clarity, music fidelity, and access to critical audio alerts from aviation apps on mobile devices. FlightLink Compatibility - FlightLink is the free, proprietary app developed by Lightspeed that turns your iPad® or iPhone® into an in-cockpit recorder, seamlessly capturing incoming and outgoing communications for instant playback or later retrieval. ComPriority™ - Never miss important radio communications with patented ComPriority, which lowers the volume of any auxiliary device automatically during radio or intercom transmissions. Auto Shutoff™ - Lightspeed’s proprietary Auto Shutoff feature saves battery life by automatically shutting down the headset power when not in use.
