these are just jacks which are meant to be mounted on a pcb. so you would need a perfboard to mount them on and then you can connect any wire/stranded cable to that.

alternatively there are jacks that make it easier to solder wires to. like these: https://www.amazon.com/Longdex-Stereo-Female-Headphone-Connector/dp/B0833WYLWQ

amazon is not a good source for components though. also none of these have any benefit over the builtin jack. You need to connect those jacks to two pwm outs on the gpio of the pi and configure the pi to use that instead of the builtin jack (so not usable at the same time)

i would suggest getting a DA converter, something like e.g. this: https://www.ebay.com/itm/265409955879 or easier and better quality yet, get a specialised hat, e.g. https://www.raspberrypi.com/products/iqaudio-dac-pro/

(these connect to i2s, please lookup in the raspberry docs or here: https://bytesnbits.co.uk/raspberry-pi-i2s-sound-output/)
