Our Verdict

Anker Soundcore C30i

Shokz OpenDots 2

The Anker Soundcore C30i and Shokz OpenDots 2 are both cuff-style open earbuds. The Anker targets a much lower price tier, but they're still decently comfortable and similarly stable. That said, the Shokz have better comfort overall and a better-performing microphone system if you care about taking calls. They're also IP57-rated, meaning the Shokz have dust and better water resistance than the IPX4-rated Anker.
