Anyone happen to know what impedance portable audio players
want for their earphones? I'm thinking of buying a small voice
recorder, and I noticed that one high-priced one specified an
impedance of only 8 ohms.
I have in-ear earphones that are 18 ohms, and headphones that
are 55 ohms. I *presume* that either of these would produce
relatively low volume when plugged into something designed
for 8 ohms. I'm hoping that audio players and voice recorders
are more typically designed for an impedence of 16-20 ohms.
