the 145 is so loud that you need to wear ear plugs underneath something like this, I knew a few captains that had this style. If your going to spend this kind of money, look at the lightspeed mach 1, you can get custom ear molds for around 50 bucks. You can plug in your "iPod" (NO SJS Bashing), or a cell phone to it, of course you wouldnt want to ever listen to an iPod or talk on the phone while flying, but its pretty cool to know you can Me personally i am happy with David Clarks for now, I find it humorous when us FOs spend a ton of money on stuff just to make us look cool. Seriously though, FOs spending 2 weeks worth of pay on a headset! COME AAANNN! might as well get a Scott Leather Flight Kit, Oakleys, and a Purdy Neat while your at it!
