I have tried a couple of these ANR type headsets and whilst I agree that the noise attenuation is to a certain extent useful when trying to make out radio instructions in a high noise level cockpit or even open cockpit, I haven't found them that fantastic. But to pay the rather ridiculous price of $1095 for this slight improvement is just throwing good money after bad. Added to this the regular requirement to change the batteries or fiddle with the volume control and bulky electronics unit ruins any perceived advantage in my view.
Years ago, I bought a pair of Harry Mendelssohn HM10 cans which were clearly modelled on David Clarke, albeit they were black. They cost somewhere around a hundred quid or so if I remember rightly and their cockpit noise attenuation due to efficient ear seals was excellent. I still have them today after many years of faithful service and they are still as good as the day I bought them.
Lastly, I have no time for mobile phones in the cockpit. Whilst flying an aeroplane is very enjoyable we have a responsibility to carry this out in a safe and businesslike manner without the distraction of fiddling around with mobile phones.
I have been directly involved with communications for some 40 years and some amazing advances have been made in this science, but I have never been able to understand why some people these days are unable to feel that they can live their lives without a mobile phone virtually growing from their ears. If a pilot needs to get a quick update on the weather, then what is wrong with using the radio and if he wants to phone someone on the ground, then how about doing so after the aircraft has landed?
