I started my Novice career with a set of Trimm Radio magnetic
headphones. They were old even then in 1966 (probably dating from
1945-1948). It hurt my ears to wear them, but lately I've been using
them again. Those old magnetic cans with their peak at 800 Hz are great
for CW. For hi-fi, there are the old surplus Telephonics headsets!
