having flown with the Bose A20 on some very long days. Headset fit is very personal, and since the ear cup shape is identical to the A20, if the latter fits you, the A30 will also!
The environment of our Cessna T206 proved to be an excellent evaluation test bed for the variable ANC modes. The High level of ANC is compar- able or better to the A20’s and offers maximum noise reduction across the
entire frequency spectrum. Selecting the Medium level was a different ex- perience, with less ANC but still very useful. In Low, the voice frequencies were increased, and the noise level was substantially higher. Except when nec- essary to better hear external sounds, pilots would not use anything other than the High ANC in such a noisy environment and turn off Tap Control to prevent activation.
Tigre and I swapped the Bose A20 and A30 headsets throughout the flight for a near-simultaneous comparison. We both felt the ANC was similar; however, I perceived it as better on the A30s. We both remarked on the reduced clamping force of the A30 --- but were happy with both units.
On to the Jets
Tigre and I decided our follow- ing test environment would be the Citation Jet (CJ), one of the jets we manage and fly. This particular CJ, equipped with the G1000 suite, has one of the quietest cockpits of the jets I’ve flown, similar to the PC-24, mea- sured by our sound meter. The next day we hopped in the CJ on a flight back from Cabo San Lucas to San Diego for the evaluation. In that jet, we have a Bose ProFlight and an A20, another excellent testing environment.
I enjoy the light weight of the ProFli- ght, which has excellent performance; however, the A20 offers a bit more noise reduction, which makes sense due to the physical mass – although
