Sliverback, if you think the DC's are comfortable, you must drive spikes with your forehead. Many years ago I purchased a Telex ANR 4000 which I used when flying turboprops like the Metroliner. I found it quite comfortable and effective. I tried a co-worker's Bose and found no appreciable difference in noise reduction. Plus the Telex was about 1/3 the price of the Bose. Used this headset until early last year for both FW and Helicopter flight. After trying the Telex Heli XT headset I upgraded to the XT and the ANR 4000 is now a backup headset. The XT was designed for helicopter operations. It is quite comfortable. You can plug your phone or ipod into the unit. While I don't do so when I have passengers, on long VFR cross countries, the ipod makes the trip go much faster. You have a multi power source. Rechargeable batteries with a recharging unit, regular AA batteries and a cigar lighter plug. Plus it is much less expensive then the Bose, less than half.
