As long-time owners of the Bose A20 headset, it has been a great investment. It may be the best aviation headset on the market. Bose recently debuted the A30’s, and we wondered how Bose improved upon its predecessor. Moreover, is it worth the upgrade? Here are the main differences between the two.
The Headband
Bose redesigned the headband on the A30s. They have a bigger gap at the top of the hinge, so there is less clamping force on the head. The 2 pads are also different, with the A30s using more of a soft padded cushion. The A20’s have a small cable between the earcups and the band, but on the A30s, the cable is internal, so there is no risk of catching it on something. Bose also moved the CG of the headset lower, to reduce neck fatigue on long flights.
Noise Cancellation
Another major difference is the noise cancellation. The A20’s use analog noise cancellation, while the A30s use digital noise cancellation. The A30s have 3 selectable levels on the control, low medium and high. High might be used for piston aircraft, while medium might be better in turboprops or jets. Low might be used when you don’t want to cut out much noise at all. Digital noise cancellation is superior at reducing lower frequency sounds.
The Cord
The cord on the A30 is longer and thinner. Like the A20, there are still 2 plug options for the headset. If you have ANR in your aircraft, the LEMO plug can power the headset. The GA or 2-pin connector still requires batteries for noise cancellation. The control unit has a hook on the top of so it can be hung.
The Microphone
Swapping the side the microphone is on is much easier on the A30. There are 2 clips on either side of the microphone base. Unclip both sides, pull out the microphone, and swap it over to the other side. (After unclipping the other spacer on the other side). There are no screws involved or tools needed. The A20s had small screws that held the microphone base, and overtightening could even damage the unit.
The Cost
The Verdict:
The verdict: We have not tried the A30s yet, but our peers confirm feeling the lighter clamping force. They also like the sound of the audio and new digital ANR, with selectable levels. However, if you are happy with your A20s, there is no need to upgrade right away. If you’re shopping for a new headset, though, for a little over $100 more, go for the newer A30s.
