I like the Sennheiser HD 280 Pro, which claims "up to 32 dB of ambient noise attenuation." I have Bose QC2 active noise cancellation too but prefer the Sennheiser. They seal out amplifier blower noise and noise from a furnace and water heater's exhaust fan that are about 20' away. The sound is crisp, they sit around my ears, not on them, and are comfortable for many hours in a contest. I realize the limitations of eHam reviews, though they score well - http://www.eham.net/reviews/detail/2951 . 73, Jim N7US -----Original Message----- Bill Frantz wrote > ...but what really works wonders are my Sennheiser noise-canceling > headphones. "Sennheiser NoiseGard™ 2.0 technology provides up to 90% active noise cancellation" http://en-us.sennheiser.com/noise-cancelling-headphones 90% reduction may sound good but it's only ~10 dB, which is typical for most active noise cancelling headphones. If you're serious about noise reduction, you should be looking for 30 dB, which is available in both "in-ear" and "over-the-ear" style passive headphones: http://www.etymotic.com/ephp/epcomp.html http://www.extremeheadphones.com/products/ex-29-headphones 73, Bill W4ZV ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
