I agree with FrankR and Delta12, the Bose QC 15 with the UFLY mic is by far the best, all in all about USD $540. It is small, compact and lightweight, has the same ANR as the Bose aviation headsets, spares are available from any Bose store, and the AAA battery lasts about 30 hours. I have used them for over 7 years now and would never go back to Telex etc. Plus you can still use them to watch DVD's on your PC in the hotel room, and even pipe the music through to them on long haul.
One headset for all uses.
