Yes, I've heard the complaints about the Koss SB-40. I've used mine
with great audio reports {even the AM fellows approve} and I've
critically listened to the radio using the SB-40. For those that have
gotten bad reports, the solution is very simple. It is known as "mike
technique".
The placement of the mike is very critical. Funny as it may seem, place
the mike about 1" off of the end of the nose. Never below it, and never
below the chin, and never in front of the mouth. It is a dynamic mike
which does exhibit proximity effect. A known fact. Below the nose
and one "snorts" like a bull as they exhale. Below the chin and the
breath pops are excessive as the upper lip and roof of the mouth directs
the burst of the "P" downward. Plus it will get baptized when one
drinks coffee. At the end of the nose, there's no snorts, there's no
breath pops, there's no proximity effect, and the element doesn't build
up spittal. And one can still drink coffee without giving the mike a
baptism.
As to EQ, and this applies for the C500 as well, just roll off every
thing below 200 Hz to -16 dB and 400 Hz about -3 dB to -6 dB. You'll
sound like Don Pardo.......assuming you have the pipes.

The Yahama C-500 and the Koss SB-40 are two good ones. Not expensive but
comfortable and good sounding for both the mike and the earphones. Either
works very well with the K3S. I know, I have all of them. My preference is
the Koss SB-40 over the Yamaha C-500.
The Koss SB-40 is essentially a Yamaha CM500 with a dynamic mic instead of an
electret mic. Some people really don’t like the dynamic mic in the Koss SB-40.
I’ve heard zero complaints about the electret in the CM500.
The Koss SB-45 is a completely different headset design that does have an
electret mic. It sells for $25, much less than the CM500 ($60).
To muddy the waters further, my Yamaha CM500 has “KOSS” molded into the
microphone plug.
