Summary: I purchased one of these for my Elecraft KX3 on the recommendation of a user of both during an on-air conversation. I thought his audio sounded very good. I paid about $55 total for this headset. I used it with the KX-3 and an adapter and it works great. I made my own adapter for a Kenwood TS-990 and I love using it with a foot switch for PTT.
Summary: I like to do a bit of contesting and so wear the headphones for hours at a time. These are among the VERY few phones I've tried that are comfortable for EXTENDED wear. I got mine for less than $50 and have used them for several years now without a lick of trouble. The mic works fine with my K3. (I must say that I do not do a lot of SSB work.
OK, I guess... good enough but uninspiring overall

Summary: I am a headset junkie and while the Yamaha CM-500 is good enough, I don't agree it is worthy of all the fuss and acolades it gets, especially with a $60 price tag. This a a reasonably well made, comfortable, and durable enough headset for the price, although I have had to repair my friend's set with a new microphone boom, and another friend's set died in the middle of the CQ WW 160 phone contest... but it is not an outstanding performer in any way.
Bang for your buck , go with it ......+++++++......

Summary: Talked to another ham on 40 meters , and I was impressed when he told me what his mic was . So I bought one myself. I have been getting good reports. Works well on my kenwood 570. My receive seems to be good also. Can not go wrong with this item. Price was right to.
Summary: I had purchased a Heil Pro 6 and it seemed uncomfortable after extended use. On a tip from AC0C I bought the Yamaha CM500. I purchased an adapter from W2ENY on ebay for the Yaesu 8 pin mic connector on my FT-2000. The audio was too hot so I added a 30K ohm resistor on pin 8, the center pin and that made the audio drive easy to adjust. During on the air testing I received one negative comment from a Heil lover in a roundtable.
Summary: My Heil ProSet was getting uncomfortable, so I went looking for a set of supra-aural phones and came up with these. Sound quality is fine for communications and the mike works well on my K3. The only real complaint I have is that the V-shaped cord feels uncomfortable. FOr maybe a penny more, Yamaha could have engineered these phones with the cord in the left side only. Still, not bad for the price.
Summary: There are better headsets, like the Flightcom Denali headset that I've used for years. But, when the Flightcom cord covering disintegrated, the replacement price was quoted at almost twice the price of the Yamaha CM500 headset. I use the CM500 now with my Tentec Orion II and it's a very nice match. The mic output is a bit higher than other mics I've used, but that's not a problem.
Excerpt: Good headset overall - but its overall quality is reflected in its price - this works OK for many computer uses, such as for gaming, and it is popular among ham radio operators as an inexpensive alternative to HEIL products... and I agree - it IS just that. But it has only average light weight construction and mediocre average mic and earphone audio.
Summary: My second review after six years using them, have two, one with my K3 and one with my IC-7700 and they work fine on both. Its been said they are overrated, I don't think so,mine has been abused falling off the floor several times and the cord never has broken. Like I said in my previous review, RX and TX audio quality is great, they are confortable in my head, I can hear hours without any ears fatigue, I do equalize the TX audio with both radios builtin EQ to make a wide...
