Hi Geoff, The only difference I see is that the Koss and the Monacor have a dynamic mic insert. The headphone are high impedance and seem to suit the K3, and the hf noise seems to less of a problem even without the mods. Since I normally only operate CW and PSK the mic does not bother me. 73 Tim gm4lmh
