I was pleased with the quality of the HMEC 400, and the 10 yr warranty from Sennheiser at the time I purchased it. The active noise-cancelling technology is well worth it, especially if you fly often. I just picked mine up at Oshkosh last weekend and have flown with it every day for the past week.įor the past 6 years, I have been flying with my Sennheiser HMEC 400 electronic noise-cancelling headset. Based on the previous Bose Aviation X, Bose took a great headset and made it even better. They both do an amazing job delivering just that.Have you been considering a new headset? The new Bose A20 Aviation Headset is top-notch quality with several excellent features. Which one is a better fit for you mostly depends on the type of aircraft you are flying, together with your personal preferences when it comes to using either an in-ear or over-each aviation headset.Īlthough the price of each headset may seem significant, we strongly believe a quality aviation headset is an investment, in your comfort, safety and health.įor the cost of these headsets, you expect the best. Conclusionīoth the Bose A20 and the Bose ProFlight Series 2 are great aviation headsets of outstanding quality. This app allows ProFlight Series 2 owners to enable Bluetooth audio sharing, connection management, pairing, unpairing, and renaming devices easy and user-friendly.īoth headsets are FAA TSO and EASA E/TSO-C139a certified, meaning they’ve been engineered to withstand even the toughest conditions. The Bose ProFlight Series 2 does utilize a newer Bluetooth Technology (Bluetooth 4.2 vs 3.1) and is compatible with Bose’s new Bose Connect App. The A20 as well as the ProFlight Series 2 have an estimated battery life of about 45 hours, but this depends on battery age, ambient noise levels, temperature, and use of the Bluetooth feature. Both the A20 and ProFlight Series 2 offer superior noise reduction, Bluetooth, audio input, auto shut-off to save battery life, audio priority to mute music when receiving or sending radio transmissions and more.īoth headsets utilize standard AA-type batteries, making it easy to quickly change batteries before or during a flight when they run low. When it comes to other features, both models are very much alike. Although we do recommend buying the Bluetooth version, as this has significant advantages that you will learn to love over time. An important side note is that the price does depend on whether you purchase the Bluetooth or non-Bluetooth version of the headset. Both headsets can be purchased for over $1000, with the Bose ProFlight Series 2 being a little less expensive than the Bose A20. But those advantages do come with a premium price. Bose’s products are well known for their superior sound quality, design and comfort. Although you could of course use the ProFlight Series 2 in a small piston-engine aircraft, you will probably not be able to enjoy the same noise cancelation as with the A20. While the Bose A20 Around-ear configuration was designed to be used in higher noise environments, like piston engine aircraft or noisy jets, the Bose ProFlight Series 2 was specifically designed and intended for pilots flying moderately noisy aircraft, such as pressurized jets. There is also a different use for both headsets, which Bose itself uses to differentiate each headset in their marketing and sales messages. With a weight of just 4.5 ounces or 128 grams, the ProFlight Series 2 is one of the lightest aviation headsets on the market. Let’s look at some of the main differences in a little more detail.įirst of all, there’s the most obvious difference: while the Bose A20 is a standard over-ear aviation headset, the Bose ProFlight Series 2 is an in-ear headset, which are usually far lighter and more comfortable to wear during longer flights.
