Re: [Elecraft] Yama CM-500 Replacement
I dug up some more info on replacement cushions. I had first bought a pair of the replacement cushions from AliExpress. They did not include the flat foam earpad covers. Only included were the ear pad cushions. I then bought a pair on eBay, item # 112534201835 that included the flat foam earpad covers. 73, N2TK, Tony -Original Message- From: N2TK, Tony Sent: Friday, January 11, 2019 2:08 PM To: 'Bob McGraw K4TAX' ; 'elecraft@mailman.qth.net' Subject: RE: [Elecraft] Yama CM-500 Replacement I had bought ear pad replacement covers for KOSS UR20, UR30 and SB40 that fit the CM-500 fine.

Re: [Elecraft] Yama CM-500 Replacement
Well, after using those Koss SB45 cans for fifteen minutes - back they go to Amazon and a brand new pair of Yamaha CM500’s is on it’s way to me. My initial feeling was that the Koss was a tad tighter, but the more I wore them, the less comfortable I was with ‘em. I guess that’s the difference between a $25 pair and a $56 pair. I hope the ear pads on this set last longer than the seven years I got out of the original. But, all things being equal, I suppose $8 per year isn’t bad… Let’s close this thread before Wayne drops the hammer on it. Thanks, and 73 to all who responded.

Re: [Elecraft] Yama CM-500 Replacement
Hi all, I still have a CM-500 sitting here but rarely use it now. Just before CQWW CW in Nov I purchased an Inrad W1 headset. Outstanding performance, and 0 fatigue on your ears. While it doesn't claim to be a noise cancelling headset, with the high kerosene heater noise in my unheated garage shack, it did seem to lower the noise considerably. For those in noisy environments, I recommend the Bose QC35 or QC25. These are true noise cancelling headphones and are pricy (I was fortunate to get mine free with United Airlines mileage that was expiring). I also have a Heil Proset which I like, but ears are sore after a 48hr contest. I've used all of these on the K3 and/or Icom 7700,7800, and 756 Pro III. 73 and HNY.

Re: [Elecraft] Yama CM-500 Replacement
If you can find ones that fit, I highly recommend a "Velour" version rather than the same old thin plastic that will eventually also flake off. I have three Sony MDR-7506s' and all have Velour pads. Once you try a set, you'll never want to go back to OEM pads. 73, Charlie k3ICH -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Josh Fiden Sent: Friday, January 11, 2019 3:05 PM To: Elecraft Reflector Subject: Re: [Elecraft] Yama CM-500 Replacement $5 free shipping direct from Koss, if these are the correct cushions. https://www.koss.com/accessories/cushions/ur20-ear-cushion 73 Josh W6XU Sent from my mobile device > On Jan 11, 2019, at 11:08 AM, N2TK, Tony wrote: > > I had bought ear pad replacement covers for KOSS UR20, UR30 and SB40 that fit the CM-500 fine.

Re: [Elecraft] Yama CM-500 Replacement
CM-500 is OK. It had so-so sound insulation (not good with loud amp) and it disintegrated. Now I use Sennheiser PC 350. Much better built and better sound insulation.

I used a pair of Inrad W1s for CQWW and I liked them so much that I asked for a pair for Christmas. I have not tried them yet. They are well made and very comfortable.

Re: [Elecraft] Yama CM-500 Replacement
With regard to "constantly plugged/unplugged", I leave mine plugged in the rear of my K3S all of the time. I use the PF2 function configured to switch between SPKR on/off and Headphones and switch the mike from the front to the rear being the boom mike on the headphones. No adapters required. Just push a button and all is correctly configured. 73 Bob, K4TAX On 1/9/2019 9:09 AM, Ken Winterling wrote: Dick, You said “My preferred headphone jacks are 1/4", and I've had trouble with 3.5mm to 1/4" adapters from another manufacturer staying solidly connected.” I agree, the 1/4” jacks/plugs are more rugged than the 3.5mm especially for devices like headphones that are constantly plugged/unplugged. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Yama CM-500 Replacement
Dick, You said “My preferred headphone jacks are 1/4", and I've had trouble with 3.5mm to 1/4" adapters from another manufacturer staying solidly connected.” I agree, the 1/4” jacks/plugs are more rugged than the 3.5mm especially for devices like headphones that are constantly plugged/unplugged. I rarely use “adapters” except for testing or “emergencies” as they put a strain on the panel-mounted jack especially if the jack is a 3.5mm supporting a 1/4” plug. That is a long “lever” sticking out of the panel on a tiny plug. it is prone to damaging the panel jack and can be easily bent by accidentally bumping it or pulling it sideways with the headphones. My preference is to use “adapter cables” with a proper mating plug and jack on a short cord. It takes the strain off the panel-mounted jack. The cord should be long enough so that the jack is laying on the operating desk when the plug is inserted in the panel jack. You can buy cords with the proper plugs and jacks or build them yourself. This is also applicable to those RJ-45 type mic connectors. I use a short CAT5/CAT6 cable with a dual female data coupler to connect the mic to the rig. Use an adapter for every mic with a RJ-45 and will probably never experience a failure of the mic plug clip. If the adapter cable clip breaks you only need to replace the short CAT cable jumper. I have used adapter cords for years and never had damage to any mic or panel jack. Ken WA2LBI On Wed, Jan 9, 2019 at 09:37 wrote: > These are personal opinions, and headphones are a personal topic...

Re: [Elecraft] Yama CM-500 Replacement
These are personal opinions, and headphones are a personal topic... I have a substantial headphone collection from all the usual suspects gathered over the years. I seem to collect these things. An Inrad W1 from Vibroplex has become my favorite. My preferred headphone jacks are 1/4", and I've had trouble with 3.5mm to 1/4" adapters from another manufacturer staying solidly connected. I find the W1 more comfortable than most other headsets I have. It has a relatively long cord and feels and looks sturdy. They grip my head a bit less tightly and feel a bit lighter than some of the other high-end over-ear headsets, but the isolation is quite good. I also like its dynamic microphone. I found a Sony wireless (Bluetooth) noise-cancelling headset WH1000XM3 on sale at Costco recently. It also has a wired connection, and should be useful to listen to content from my mobile phone or tablet when on an airplane, or to plug into the plane's entertainment system. It lacks a microphone. It's relatively light and comfortable, but I haven't yet used it for a long contest. My old favorite Sony MD-V headset is still sometimes a good fit. I think it's now called an MDR-7506. It also lacks a microphone. I find it helpful to change headsets from time to time, just to change the pressure points. So I have several headsets around... 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Richard Thorne Sent: Wednesday, January 9, 2019 04:11 To: James Bennett ; Elecraft Reflector Reflector Subject: Re: [Elecraft] Yama CM-500 Replacement Jim, I have a pair of Yamaha C-500's which I like a lot, however, I wanted to try something different that was built a little better.

Re: [Elecraft] Yama CM-500 Replacement
I have and use the Koss SB-40. I get great audio reports. Yes, I agree, if the mike is not positioned correctly and the TX EQ not set correctly, it can sound bad. So can any other mike where good mike technique and application is not correctly used. 73 Bob, K4TAX On 1/8/2019 11:51 PM, Walter Underwood wrote: I’ve heard good things about the Koss SB-45.

Re: [Elecraft] Yama CM-500 Replacement
I suggest another set of CM-500's. They may last 2 years, 5 years or 10 years before they are headed for the trash. Just look at it as a consumable item and that is just the cost of ownership. 73 Bob, K4TAX On 1/8/2019 9:00 PM, James Bennett via Elecraft wrote: Sad to say, but my trusty old CM-500 headphones with boom mic finally bit the dust.

Re: [Elecraft] Yama CM-500 Replacement
Jim, I have a pair of Yamaha C-500's which I like a lot, however, I wanted to try something different that was built a little better. I picked up an Inrad W1 from Vibroplex. Physically they are built much better than the CM-500. They are over the ear like the CM-500's and they do a bit better job keeping the noise out. They are a little heavier than the CM-500 and have a a little more pressure (ie clamping) on your head. You will need a 1/4" to 1/8" stereo adapter for the phones if your rig has an 1/8" jack for the headphones. I've had the headset since October and used it for a serious effort during Nov Sweepstakes. I had no issues during the 24 hour contest. They are keepers in my opinion. The mic is dynamic and I'm getting good audio reports. They are in a different price range than the CM-500 but worth adding to your list of candidates.
