Where did the 3 pin stereo plug come from?
It was invented for use in telephone switchboards in the 20th century and is still widely used, both in its original ¼″ (exactly 6.35 mm) size and in miniaturized versions: 3.5 mm (approx. 1/8″) and 2.5 mm (approx. 3/32″). The connector’s name is derived from the names of three conducting parts of the plug: Tip, Ring, and Sleeve.

Can a stereo plug be plugged into only one ear?
Plugging a stereo plug into one of the two mono jacks typically results in the audio coming into only one ear. Adapters are available. A short-barrelled version of the phone plug was used for 20th century high-impedance mono headphones, and in particular those used in World War II aircraft. These have become rare.
What kind of stereo cable do I need for mono?
No adaptor plugs seem to exist for 3.5 mm stereo plug to 6.3mm mono socket. So, I used a 3.5mm stereo plug to 2x RCA plugs with a short cable. Then a plug that is 2x RCA sockets to 1x RCA socket – true stereo to mono “joiner”.
