Our Verdict
Anker Soundcore C30i
EarFun OpenJump
The EarFun OpenJump are better for anyone prioritizing comfort in their open-fit workout buds, while the Anker Soundcore C30i offer a more controlled sound and a longer continuous battery life. Both remain highly stable during exercise and let you hear everything around you, and neither produce much bass at all. The large ear-hooks of the EarFun fit more comfortably over long sessions, but the clip-on Anker are smaller and might be a better fit if you wear glasses or have longer hair. That said, we found the Anker less comfortable over long sessions, although their battery does last longer than the EarFun.
