A parade of quarter-inch-to-3.5-mm adapters I got with various pairs of headphones.
The last three are, of course, all from the same model of headphones: Philips SHP2500. The one on the left is from a Sony pair, I think.
I use one of these (second from left) in my amplifier, which has a quarter-inch output jack, to adapt it to the 3.5-mm cable to my computer’s line-in jack.
