Paul:
I bought a pair of DC's 30 years ago...still have them, they work great. 20 years ago, a young friend of mine barfed into the mike. I sent it back, years after the warranty had expired, and asked for a quote to refurbish. They sent it back quickly, completely refurbished, new cords, etc, no charge. The company is that good. With regard to ANC, don't even think about not getting it. I know that it seems like an expensive option now when you are starting out but if you continue to fly, you will find that the upfront cost is nothing compared to the cost of hearing aids that you will eventually need.

Jonathan,
they are pretty much an all-plastic headset No, they are not. The metal is covered by plastic, that's all. -- Thomas Borchert (EDDH) |

There is some question of the value of ENR (Electronic Noise Reduction) in avoiding future hearing loss. Our company investigated supplying ENR headsets in a high noise area, but decided not to, since there was no demonstrated value. In short, ENR only works on lower frequencies, and those frequencies typically don't affect hearing as much as higher frequencies. There were a couple of areas where there might have been some benefit, but they were unquantifyable, so the company couldn't put a dollar value on the systems. The use of the systems might have led in a possible reduction in fatigue, resulting in improved alertness, and there might have been improved clarity in conversations, reducing communication error. |

That's why you should never rely on bean counters when it comes to
safety, security or comfort. On Sun, 18 Apr 2004 18:56:10 GMT, James Robinson wrote: Pete Brown wrote: With regard to ANC, don't even think about not getting it.

All joking aside, the single thread that seems to consistently bind all
models of lightspeed is their unreliability. From what I've read (from people who have allegedly owned them) I wouldn't touch them with a 10 foot pole. "Thomas Borchert" wrote in message ... Cockpit, I've read of people who've sent them back a dozen times or more Well, I'd wager you've read about exactly ONE person who's done that. And he's gotten one for free now. You also find one person here who hates his (ex-)Cirrus. This is Usenet... -- Thomas Borchert (EDDH) |

"Paul" wrote in message ... Hi I am a student pilot hoping to take my checkride within the next month (PPL/A). I am after a David Clarke Headset but am not sure which one to buy. Does anyone know of a good website that has independent reviews on all the Dave Clarke models, the only reviews I can find are either on the David Clarke website or on pilot supply websites but none of these seem to be independent or detailed enough to make my decision. I am not really interested in the detailed specifications, I am after reviews from pilots who have used them (comfort, features, weight etc..) ideally comparing the pro's and con's between the different models. Thanks Wore a pair to Vermont and back from Austin, Texas once; "David Clamps" is apropo. OTOH a solid, well engineered product suitable for military use. Blue skies H.

There is some question of the value of ENR (Electronic Noise Reduction)
in avoiding future hearing loss. Our company investigated supplying ENR headsets in a high noise area, but decided not to, since there was no demonstrated value. In short, ENR only works on lower frequencies, and those frequencies typically don't affect hearing as much as higher frequencies. With DCs the passive attenuation is on par with other (non ANR) headsets. The ANR is ADDITIONAL attenuation, with main benefits being increased clarity of speech and less fatigue. They're really designed for aircraft type noise levels (which in the big picture of things aren't really that noisy inside) - they wouldn't be sufficient for such things as daily chainsaw useage. If you need high frequency protection from relatively high noise environments then an aviation type headset isn't the right tool for the job. |

Which David Clarke models offer ANR?

A recent review that I read (cant recall where, sorry) gave the Bose a low mark for noise reduction and suggested Sennheisser as the best performing. I'm a bit of an audiophile and I can tell you that nothing beats Sennheiser's headphones. Bose's don't even come close. Never tried their aviation headsets but if they are anything like as good as their hi-fi stuff they would be well worth getting. K |

The financial people would have been delighted if there was any benefit, since payouts for occupational hearing loss are quite high. |
