I have had a chance to try out the Bose Proflight Series 2 over 100 hours of line flying. I am currently flying the Embraer 175 and we get a good mix of various flight regimes during low level and high level flight with the regional flying we do. I may also add that I had the chance to try the initial version of the Bose Proflight as well. I must say, Bose has hit the ball out of the park with this Series 2 headset. It is simply perhaps the best high-performance headset I have used in 11 years of flying. The improvements that have been made are apparent and noticeable. The stability of the headset on the head is fantastic and you can barely feel the headband due it being so light. The longest flight I had a chance to test it on was 3.8 hours block, and after continuous wearing I had no noticeable hotspots or pressure points. As far as the earbuds go the ANR is fantastic I don’t know how they did it but the amount of noise reduction is impeccable. I also like the fact that it has various modes of ANR that can be tailored to specific operations, as the ANR reduction targets different noise spectrums that vary from aircraft to aircraft. This feature is very useful if one desires to use the headset in more than one aircraft. The tap through feature now works flawlessly. The original Proflight had a tendency for the tap through to activate on TO or landing, however that issue has been fixed with the Series 2 version. It works so conveniently that I now have both earbuds in on pushback, activate the ANR, and tap one ear bud to hear the surroundings until tapping it back into ANR after engine start. A very well thought-out and amazing feature that I now have come to immensely enjoy having. Now onto the chord, it is AMAZING. Bose have gone ahead and completely redone the chord to be extremely mobile and easy to manipulate. Is so thin and light that clipping it and getting it out of the way in the flight deck has become a complete non-issue. The chord is simply now just right. The Bluetooth on the module has been the easiest pairing with the phone I have had with any headset. It is so fast that it pairs within 1 second of flipping the switch on the control module, and away I am making crystal clear calls and/or playing music. The audio quality is outstanding and the module has a switch to control the phone or volume music level. The headset case is super convenient and super easy to get the headset into. Simply putting the headset into the case and wrapping the chord around neatly takes me 5 seconds tops and into the flight bag it goes. I must say the case is super nice and has a convenient pouch for spare batteries and tips. All in all, this might be the last headset I buy for quite a while, or at least for the next 10+ years. Hands down I recommend for you to try it and/or purchase. I certainly won’t ever be going back to wearing a regular on-ear headset again. Bose has listened to pilot s needs and what they want in high performance flight decks the Proflight Series 2 headset is the proof of that effort.
