![]() Bose recognized this and, during a press conference at Sun ‘n Fun, assured members of the press that the headset went through no fewer than 145 tests to determine its durability during the five years it was under development.įLYING had the opportunity to test the headset before release. Headset plugs and cables take a beating, especially at the flight school level. The zippers move easily, and you do not have to wrestle the headset into the bag. It is smaller than that of the A20 and has a zipper pouch for extra batteries. The carrying case for the A30 is designed for maximum protection and minimal space disruption in your flight bag. The cable has two clips to secure it in place no matter which side of the cockpit you want it on. For pilots who don’t like cables all over the cockpit, this is a bonus. It can be reset to dress left or right by unplugging and plugging it in on the other side, similar to unplugging or plugging in a smartphone on a charger. The headset cable can be mounted on either side of the headset without using tools. You need a small tool to press these switches, like a pen or tiny screwdriver. There are Tap Control, Priority, Intercom, Auto Off, and Auto On switches. The operation switch functions are located inside the battery compartment. Tapping an ear cup twice reduces the noise canceling in that ear to the low setting so you can hear your copilot without having to remove the ear cup altogether. When the high and medium modes are engaged, the A30 has tap control for talk-through communication. There is also a low mode, recommended for commercial airliners and jets, or when a pilot needs to engage in interpersonal communication outside the intercom. The medium mode, designed for business jets, wasn’t quite enough for the situation. High mode is recommended for louder cockpit environments such as the propeller-driven aircraft that dominate the training fleet. On the exterior of the battery compartment, there is a switch to adjust the sensitivity of the headset using a scale of high, medium, and low modes. The battery compartment for the A30, like the A20, is easily accessible without the need for tools. ![]() Both result in less clamp force, which tends to give the impression that the A30 is significantly and noticeably lighter than the A20.The cups on the A30 sit lower on the ears, giving the wearer a feeling of stability. ![]() ![]() Also, the headband padding on the A30 is more streamlined and effective than the faux fur-like band of the A20. The A30 has a pivot spring rather than a hinge like the A20. The headband of the A30 is a different style than in the A20. That’s because the weight of the A30 is distributed differently along the headband. While that’s not much of a difference according to Bose, you will note that the A30 has less clamping force. How much? According to Bose, the A30 tips the scale at 14.2 ounces, and the A20 is 14.46. Right out of the bag, the A30 is slightly lighter than the A20. The latest generation of Bose headset, the A30, was released Tuesday, and although it may be hard to believe, it is an improvement on the A20 in several ways. I understood why the Bose A20s were so popular with pilots. I still remember the first time I wore an active noise reduction (ANR) headset-I had thousands of hours underneath a pair of 1980s-era David Clarks-when I hit the power on button, there was a noticeable reduction in noise, and transmissions became more clear.
