[Boatanchors] Early transistor radio earphone.

[KEN]

Hi Gang,

I am in need of one of the early earphones that came with the first transistor AM radios.
Those earphones "plugged" into the outer ear canal.
Way back in 1959, I lost hearing in my left ear. Recently, I believe I have discovered
response at one point in the audio spectrum with amplification. I believe if this is true
I should be able to copy CW at that spot in the audio spectrum. I need to keep the
amplified sound from being picked up with my good right ear hence the type of 
earphone that "seals" the sound inside the bad ear canal . 
I am aware of "bone conduction" and "tissue conduction" but I don't think this will be
a problem if I can keep the sound thru the air from my good ear.
If successfull, maybe I can read CW and monitor another circuit either CW or Phone,
in other words, work "split phones". Wish me luck!
Please search your junk box. Thanks,
