Best Head set
Bose is good but no longer has a corner on the market and are very expensive compared to the other top of the line headsets. I assume you are talking about active noise canceling. You Choice is Bose, Lightspeed, Peltor, DC, Telex................... The list is long. The old "Get what you pay for" is true but Bose is at real premium and the performance of the lesser priced Lightspeed's for example are as good or better, making them a better value. However the Bose are great, but some people don't like all their construction features (form/fit/function).
You can look at charts of "dB" noise reduction all-day but I find the "form, fit & function" is the most important. Which means, how does it feel on your head, size, weight, battery pack/controls, battery life and special functions, like cel phone input and stereo music. Are you going to listen to music? A good headset may not be good for quality stereo music. Research all the comparisons and go to a store or airshow and try them all on. Demo it in an airplane if you can or at least plan on wearing it for more than 30 seconds. I would suggest if you are a bargain hunter and don't mind used, try eBay. The lightspeeds are probably the best value/quality and you can get good deals. Lightspeed has improved components over the last few years to improve music playback even more. I would talk to them directly if this is important. If music is not important, you don't have to buy the top of the line model. Cheers George
