Bose A30 Aviation Headset – Low Impedance Heli Straight Cord
Engineered for helicopter operations requiring low impedance audio, the Bose A30 Low Impedance Heli variant features a U174 straight cord connector optimised for specific rotary-wing audio systems. All the comfort and noise cancellation of the A30 — without Bluetooth, for operators who prefer a straightforward wired setup.
Breathtaking Comfort. Showstopping Quiet.
The A30’s lightweight design with low clamping force provides unparalleled comfort over long flights. It upholds the acclaimed noise cancellation of the Bose A20 but features a lower overall weight and 20% reduced clamping force — so you arrive as fresh as you departed.
Setting the Bar for Long-Term Comfort
Engineered for pilots who spend hours in the cockpit, the A30 features an ergonomic around-ear design that distributes weight evenly and reduces fatigue. Whether you’re flying circuits or crossing oceans, the A30 keeps you comfortable from takeoff to touchdown.
Audio on Your Terms
The A30 features the best balance of attenuation and audio clarity of any pilot headset on the market. With three selectable modes of active noise cancellation and tap-through communication, it provides industry-leading performance across all types of rotary-wing aircraft.
Designed to Perform
With a sleek, modern design and a toolless side swappable mic, the A30 is engineered for versatility in nearly every cockpit environment. Made with materials chosen for strength and durability — without the bulk and clamping force of typical aviation headsets.
Built for the Long Haul
The A30’s low impedance configuration is purpose-built for helicopter audio systems that require it. A clean, wired-only setup means one less thing to manage in the cockpit — just plug in and fly.
