[Elecraft] Cheap headphones

[Michael Usher AG6MK]

They look to be virtually the same headset.

Visually, the earcups and headband are identical.  The mic boom looks to be physically slightly different.  And the Koss has single side cable, vs dual on CM500.

The CM500 I have has "Koss" molded on the 3.5mm connectors.

From website specs, the Koss has lower impedance (100 vs 120) and slightly better sensitivity.

My bet is that the Koss would be a slight improvement on the CM500.
