[Elecraft] CM 500 Ear Covers

[Walter Underwood]

Replacement ear pads are available, but the internal wiring is very fragile.

I managed to get the replacements on, but broke a wire. After four breaks and three re-solderings, there wasn’t enough wire left to work with, so I bought a new headset.

The Koss UR-20 is the same headphone as the Yamaha CM-500 and Koss SB-40, but without a boom mic. The link to these replacements was posted in this email reflector (11/1/19) by Josh W6XU. These are the ones I ordered.

This video walks you through the replacement steps.

This guy just glued on the new ones, which might be a safer approach.
