I ordered from radioshack.ca the 330-1198 headphones.

That 33-1198 has an 1/8" mono plug. If your receiver has a 1/4" jack, you'll
still need an adapter, such as R.S. 274-325.

A caution about using headphones on SW. Because of possible static crashes and
other sudden loud noises, especially when seeking weak signals, don't wear your
phones completely over your ears. Professional radio operators and smart
amateurs slide them off some, usually forward, but whatever works best.

Years ago, while working on a marine receiver, and I was listening to SW (not
LW), there was a loud pop, and my right ear became damaged. It took years for
wax to keep from building up and blocking my hearing periodically, Even today,
the hearing in my right ear begins rolling off around 10 kHz.

I knew better than to fully cover my ears, but the shop was noisy and the
phones had no cushions, so I had the things pressed to my ears.
