Eh, I have used a Bose X and the Mach 1 in the Saab. I am still using the Mach 1. Just a much better headset. No real difference in dealing with the noise and you can't beat the price, the plug in capability, and the extra space in the flight bag. FWIW the Bose is just not worth the price. If it was 500 bucks it would perhaps be a bit better choice, but I'd still prefer the room in my flight bag... The bose is also as durable as a piece of balsa wood. In just over a year of 121 flying I had to send the bose in 3 times for repairs due to a bad ground/buzzing problem.
