Fairphone make headphones, slightly over your budget but worth a look. I’ve had mine for two months and they’ve been solid performers so far. More importantly, Fairphone places an emphasis on ethically-sourced and easily-repairable products with a long lifespan. Their new phone comes with at least eight years of support, for example.
Edit: alternatively, find a decent pair of dumb headphones with a detachable cables, either USB-C or 3.5mm, so you’re less likely to damage the cable and, if you do, you don’t need to replace the 'phones.
So I’m not hoarding Meshtastic nodes, I’m just getting ready. Got it!
