Bose A30 Wireless Headset

The Bose A30 Aviation Headset is best utilized where noise is pervasive, comfort is required and communication is critical. The Bose A30 is Bose’s highest-performing, full-featured around-ear active noise cancelling aviation headset to date. With 20% less clamping force than the Bose A20 and redistributed weight for superior on-head stability, the comfort of the A30 rises to the top among over-the-ear form factors. The Bose A30 Aviation Headset with Bluetooth further improves upon the comfort and functionality of the Bose A20 with a new acoustic design and a fully digital active noise reduction (ANR) system. As the first-ever around-ear aviation headset with three modes of user selectable noise cancellation, the Bose A30 enables pilots to control the noise they hear in the cockpit. Plus, the Bose A30’s optional Bluetooth interface and tap control for talk-through communication offer versatility for pilots across all aircraft. This pilot headset also features a toolless, side swappable boom mic and down cable, and its improved carry case has internal zippered storage and padded sides for extra protection. Review: Very good - Very good! Review: product did not work as it should - Briefly I gave it 1 star because the product did not work as it should. At least the manufacturer should indicate "Not for helicopters" Details: I am a professional helicopter pilot and the A20 is part of my life. I have two now, one built into my helmet, and one for free wear. I read all the reviews before buying and honestly did not really believe in the negative ones. As soon as I got the A30, I jumped into the helicopter for 7 hours of work. The first impressions were very positive; I liked the non-slip plastic on the new battery compartment, the thin cable, and less pressure on the ears. Noise cancellation worked well. The first negative impression came after the first radio conversations. The sound of the ATC seemed very "dry", unnatural. I would say that the sound frequency range is shifted to the top (high frequencies prevail). In reality, I think this is the peculiarity of the digital processor. The worst thing happened later. At some point, the right earphone started making a Bang-bang-bang sound. It was very loud. Not only couldn't I hear the ATС, but it also was hitting my eardrum hard. It looks like the digital noise cancellation picked up some vibration or sound or both and started autoresonance. I tried for 20 minutes to fix it; I tried moving the headphones on my head, pressing them harder, but nothing helped. Eventually, I had to turn off the noise cancellation and continue the flight without it. It's good that there was no tense radio communication when this happened. Imagine that you went deaf because of a Bang-bang-bang somewhere in B airspace or were working in close proximity to other aerocrafts. It’s really not safe.
