A great product when in need....
I used this product in the past on crystal radio sets, it’s too bad that I can’t find any old crystal headphones from the past, sticking things in the ear can be a pain....Still a great product...

Gets the job done
I use these for building crystal radios and they work perfectly. I just remove the auxiliary end then separate and strip the wires, and they are ready to go. I've used several of these earpieces and they always work just fine. The only thing is they are fragile, so you don't want to drop them..otherwise the plastic part that goes in your ear pops right off. I've used a small 3d printed plastic cap to replace one piece that has broken off before, and it still worked good as new. Would recommend!
