Caveat to those considering buying PineBuds for "open source firmware": OOTB they come with fully working but proprietary firmware (part source-available SDK, part closed). The hardware is not 100% documented. There is open firmware they can run, but for example ANC has not been replicated yet, at least not well (and personally I love the ANC enough that I kept the factory firmware)-:

- Pine64's general model is selling cheap, quite-good, not-fully-documented hardware with expectation community software will(?) grow around it. Some of their products grow fantastic support, some less so, some remain "dev kit" — do your homework.
