Comfort and quality come together with the Pilot USA PA-1779T ANR Headset. Outfitted with closer tolerance military components, this headset offers additional active noise cancellation at 100Hz. It also sets itself apart by being the only self-contained ANR available that has a rechargeable NiMH battery along with a standard wall charger. Used with both USA and Russian space programs, this flexible headset is also comfortable, thanks to the sheepskin fleece heat pad and the silicone gel ear seals. All of these features make this one of the top choices on the market today.
