Hi,
I bought a pair of Koss SB-45 when my CM-500 ear cushion covers started
disintegrating leaving the dreaded black dandruff. My wife fabricated a
couple of fabric covers and the problem was resolved. Recently I was
sent a pair of fabric earphone covers by a friend obtained from Amazon
who for some reason won't ship to the Falklands. They are simple
elasticated covers and they slip over the ear pieces. A satisfactory
extension to the life of the CM-500.
Returning to the Koss SB-45. I substituted them for the CM-500 and a
local could hardly detect any difference. The mic boom is a bit more
springy and take a bit more effort to tailor to the individual
preference. The cord is much lighter than the CM-500 which could be a
weak point. Mine have been in the draw for a couple of years unused
because the CM-500 are refusing to die.
Regards,
Mike VP8NO

I’ve heard good things about the Koss SB-45. It has an electret mic and is
about half the cost of the CM-500, at $25. I have not used the SB-45.

I would not get the Koss SB-40. That looks like the Yamaha, but has a dynamic
mic that has gotten some bad reports.
A while back, I took a close look at the mic plug on my Yamaha CM-500 headset.
It is labeled “Koss”.
