Lightspeed Sierra 4000
The Lightspeed Sierra redefines performance and value in an ANR headset, with several advanced features found in much more expensive ANR's. Sierra has an integrated cell phone BlueTooth interface, plus a wired interface to any portable music device – and the music will automatically mute for incoming transmissions.
Lightspeed Sierra ANR Headset Battery Features
Sierra will operate for up to 40 hours on two "AA" batteries, and the battery status indicator will let you know when the batteries are getting low. The auto shut-off feature keeps the batteries from discharge if you forget to turn the ANR off. Sierra has dual volume control, weighs 16 ounces, and includes a padded headset bag, microphone windscreen, music interface cable, and Lightspeed 5 year warranty.
- Superior quiet – Active noise cancellation over a broad range of low-frequency noise brings state-of-the-art technology to Sierra.
- Comfort and durability – Weighing just 16 ounces, Sierra is light on the head. Covering nearly 10 square inches of surface area, the ear seals create a better seal and greater distribution of side pressure.
- ComPriority – Never miss important radio communications. ComPriority features Lightspeed-patented technology that automatically lowers the volume of any auxiliary device during radio or intercom transmissions.
- Reversible microphone – Our unique design allows for right or left microphone placement so you can fly with technology on your side.
- Mobile phone and music connection – In addition to full Bluetooth connectivity, Sierra offers an integrated control box auxiliary input, making it easy to connect a mobile phone, iPad or music/audio device.
