Well I drove out to the Bose store today to put on a set of Q15’s. I have to say I was somewhat disappointed. I'm not sure what I was expecting, never put ANR on my head in my life until today, but I guess I thought they would be amazing or something. Granted I was in the Bose showroom floor and not the cockpit, but they didn't seem to reduce anymore noise than my Flightcom clamps (non ANR) - Obviously they are immensely more comfortable I'll grant you, but I could still hear a lot of sounds coming from the outside: I could hear my kids laughing, whining, crying, and people chatting 10 feet away. They even had a simulated jet noise that came on in the store periodically and I wasn't that impressed with the reduction in that sound either. (And yes, they were turned on) I mean wow, they were cool, and the ANR was remarkable, but when I got home I put on my clamps to compare and my kids sounded about the same as under the Q15s. I'm not looking to upgrade for comfort only at this point; I’m looking to cut out the deep low roar of the prop while climbing out at 900 Np. Will the Q-15's do that or are they just a more comfortable way of achieving an 'equal' degree of noise suppression as the old tried and true "clamp and seal" David Clark style method?
