You can’t go wrong with a great pair of $10 IEMs—especially when they look, sound, and fit like earphones several times their price. Enter the Massdrop x HIFIMAN Bolt: one of those small daily essentials you’ll always be glad to have around. Featuring a well-built aluminum housing with silicone ear tips and one 9-millimeter dynamic driver per side, they provide good noise isolation and a fun overall sound. The sound signature includes warm lower mids, clear and present mids and upper mids, and highs that are slightly emphasized, though less so than the low end. For taking calls and changing tracks, the oxygen-free-copper cable is equipped with a one-touch condenser mic and remote. And for a comfy in-ear feel, these IEMs are extraordinarily lightweight: just over half an ounce.
