I have both current Linkbuds. I love the concept of the first one but they are uncomfortable for me no matter how I wear them (unless I damn near have them hanging out of my ear, but then they sound bad and fall out easily). The S model is one of my favorite earbuds I own. Super small and light with great sound and fantastic ANC and passthrough. Not quite the same as a truly open earbud though. I want to try the BOSE clip on one’s, but like you said they are pricy.
