Earbuds drive me nuts. Great for hifi listening, but unpleasant for ham radio — especially for extended use over several hours.
Impedance isn’t all that important. Most hifi type headsets or earbuds will work. My personal suggestion — if you want to move up a step from the common CM500 headset (which is ok and inexpensive, flimsy, and does not block out external noise in any useful way), would be to look at the new “portable” headsets from Arlan Communications — the RS10SL (headset only) or RS50SL (headset mic). Neither are expensive relative to “high end” earbuds (which are wasted in the usual ham application anyway). And if the new Arlan’s are even anywhere close to the RS60CF, they’ll be about as good as it gets. I use the RS60CF on both a K3 and KX3 at home and in the field Thinking about adding the 50SL for field use specifically, although the 60CF isn’t really that much to carry and fits in my equipment case. I’ve used very high end Shure earbuds in the past because I had them. They’re compact, and wonderful for a concerto or two, or an hour’s worth of listening. But for several hours of continuous ham radio use, really uncomfortable and bothersome.
