I'll share with the group a very positive experience with an excellent set of headphones I've not seen reviewed for radio before - Sennheiser HD280 Pro, online most places for $99. OK, it's not the cheapest set out there like the two mentioned here, Koss SB-45 and Yamaha CM-500 (I too have the CM-500, the response is nice and crisp but the Sennheiser is superior and more comfortable than the Yamaha), but it is extremely high quality from a famous EU maker. I actually bought the Sennheiser for another use in the shack (digitizing old reel to reel audio tapes and I needed a studio reference source). These phones are terrific, with 32db of isolation. The over-the-ear cushions are very deep - a little over an inch - and I operated a whole contest weekend with them at the CQWW CW at VE3RZ's M2 with my K3 and SPE Expert 1.3K-FA. In SS CW, I copied many west coast CW, even qrp with these phones. Very comfortable on the ears, and very quiet - no outside noise. These are rated as recording studio quality phones. The cable is 10ft long, and the weight is only .49lbs. It comes with a 1/8in plug but includes a 1/4 in adapter. Here's a link with the details for anyone interested http://www.sweetwater.com/store/detail/HD280Pro?adpos=1t1&creative=83049424441&device=c&matchtype=b&network=g&gclid=CKjIwJXe_8kCFdQYHwodrokJWQ I have no financial interest in anyone selling them, just love the product. 73 Darrell AB2E

Mine is the one with 3.5mm connectors, not the USB version. I also have a CM-500. I was going to post a review here after wearing the SB-45 all next weekend in the RTTY Roundup, but here are my first impressions. The microphone quality is fine. The SB-45 needed about 3 dB more boost in TX EQ #4 to sound like the CM-500. The mic is an electret. Do not confuse this unit with the SB-40, which has a dynamic mic, and apparently doesn’t sound so good. The audio out of the headphones is also fine, just as good and loud and distortion-free as the CM-500, at least for communications use. I haven't tried either headset on music. I wore them for 1.5 hours on a long-winded net this morning, and they were totally comfortable over that time period. I do wear eyeglasses. People on the net said the audio sounded just like the CM-500. I'll give a better long-term comfort report after the RTTY Roundup. The cord is nice and long, and the mic and headphone wires can be separated easily to go to different places, after cutting a little rubber thingie that keeps them together. My mic goes to the back of a computer on the floor, and my headphones go to an SO2R box on the table. The SB45 is around $25 on Amazon, compared to $55 for the CM-500. I think this headset is going to be a keeper, but I’ll give a long term comfort report next week.

Has anyone used/using the Koss SB45 headsets on their K3? I have the CM-500 and I am on my second set but again the padding is starting to deteriorate so before they look too ratty, figured I would get a backup and as the CM500 are not available in VK but the Koss SB45 are, I would appreciate any comments/advice the list may offer. Just to let you all know, I love my Yamaha cm500 BUT, shipping cost from the US is really quite ridiculous these days and the AUD has fallen off a cliff and the parachute failed to open...:-) The Koss SB45 are $69.00 AUD, free shipping. I like free...:-) TIA 73 Gary -- *Gary - VK1ZZ, K3NHLSkype: Gary.VK1ZZhttp://www.qsl.net/vk1zz <http://www.qsl.net/vk1zz>Motorhome Portable* *Miss Behavin'* *Elecraft K3KPA500FT #18KAT500FT #007* ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
