The earphones are 22 ohms -- they're tiny. My concern with the ganged one is the tolerance on the matching between the two channels -- especially at low volume levels, it only takes a little difference to sound off, and I'm likely to be using them at a lower volume level.
I'll see what else I can find -- maybe there's a cheaper fixed one, or an affordable variable one that has good reviews. 73, Julie On Wed, Mar 10, 2021 at 2:32 PM Mark Goldberg <marklgoldb...@gmail.com> wrote: > They are very short on specs.
