Sometimes I listen to music when going to sleep. For this the primary need is earbuds that are low profile enough to not hurt your ear that you are lying on. Also needs to have a three-ring jack.
A while ago the pair I'd been using developed the typical 'intermittent wire' problem. So I looked for replacements, aiming for 'cheapest possible while small and functional.'
The old one I'd bought from Myers years ago. Small, comfortable, and had exceptionally flexible cables.
But when I tried Myers again (shortly after lifting of extreme covid restrictons) they don't have any electronics section at all.
JB HiFi has nothing but high cost earbuds, all with microphone and 4-ring jacks. Cheapest about $17.
Tried online and found these. Kmart, $1.70 each bought online. I bought 10. They work fine. Come with three pairs of silicone cups to suit different ear sizes.
As for fidelity, I wouldn't know. I have high-freq hearing loss. They sound OK to me.
