Clarity Aloft Aviation Headsets are the result of our commitment to the highest standards in aviation communications. These headsets contain the most technically advanced components brought together from diverse experts in audio communications. The Earpieces The Clarity Aloft earpieces are used to improve both hearing protection and speech communications. Each earpiece includes a miniature speaker that reproduces speech signals from the aircraft audio system. The replaceable compliant foam tips (Comply™ Canal Tips) which attach to the earpiece contain a pathway for the sound to travel from the transducer to the ear. Used by the military for helicopter pilots, both components of the earpiece, the transducer and Comply Canal Tips, have been tested, used rigorously and meet the most exacting military standards. Replaceable Foam Tips The superior seal is achieved with our patented Comply™ Canal Tips, which are used in high-end hearing aids. These viscoelastic foam tips provide the highest level of hearing protection available by any method including active noise reduction. (ANR) The outstanding noise reduction (35-45dB) in the speech frequencies between 400 to 4,000 Hz results in unsurpassed clarity of voice communications. Resembling foam earplugs, the foam tips are so comfortable because they are compliant to the shape of the ear. Considerable sound science history backs up their impressive performance. Technical specifications on our viscoelastic passive noise reduction (VPNR) are included in the Owner’s Guide. The Noise-Cancelling Microphone The noise-canceling microphone used in the Clarity Aloft Headset is a high fidelity noise canceling Electret Condenser microphone with performance optimized for speech frequencies in extremely high noise environments. Stage performers and musicians use this same microphone because they must insist on the highest level of sound reproduction. Push-to-Talk Feature With the special needs of professional flight instructors in mind, Clarity Aloft Headsets include an extra Push-to-Talk button on the Volume control box. This extra PTT serves as a back-up system to the aircraft yoke button. Low-Profile Headband With its flexible boom arm, this featherweight band is the same one sported by stage musicians and professional performers the world over. Balance and comfort are the result of its elegantly simple design. The mic boom can be easily re-positioned for eating and drinking during flight without disturbing your earpieces.	The earpiece and Comply™ Canal Tip work together to produce the clearest sound available in an aviation headset. The noise-cancelling microphone is optimized for speech frequencies in high noise environments. The Push-to-Talk button is designed with flight instructors in mind. The low-profile headband is featherweight and comfortable.
