Yeah Sprocket Check, I have a Mach 1. Not a bad headset (note: not ANR) which I have had customised with a pair of unique ear moulds made for me by the local hearing clinic. If you go Mach 1, it is a mod I highly recommend. There's no need to do so via the Lightspeed-supported method which you will doubtless have read about, and pay substantially more for -just get in touch with your local hearing clinic. The whole process took about 30 minutes and cost well under AUD$100
I've used them a couple of times in GA lighties -probably not the best environment for them in noise-retention terms, although they are adequate- but they work a treat in Gas Turbines, are light & comfortable. Only gripe I had was connecting a (Vodafone) GSM phone to them -there is a cyclic 'pulse' for wont of a better phrase, when the phone is active that is bloody annoying. A superb response with the iPod connected.
