To DIY a good quality crystal radio earbud from a piezo-electric buzzer that has equal or even better performance than a genuine crystal radio earbud

Genuine Crystal Radio Earbud (warning - for reference only, these earbuds often got connectivity issues where the contact with the internal disc is loose and will loose after a few months of use and hard to repair. So, it may be much better to DIY one using the buzzer (see above). However, if you just want to have a few of the genuine crystal radio earbud, it’s no harm to buy one for collection purposes knowing that it may fail in some time due to contact loosening issues).
