@jol wait... this site';s layout is confusing...
I meant fairphone discontinued their controversial bluetooth in-ears. Wired in-ear headphones in general are having a bit of a renaissance with so called "chi-fi". Chinese brands launched after 2015, that sound great for $20-$50. Check out Crinacle's youtube channel

@jol @Enk1 the earbuds aren't on sale anymore, and they did release proper modular& repairable "Fairbuds XL" over-ears.
