#571 Sennheiser OCX 685: $69 Discontinued eBay
Pros: A sports earphone with ear hooks that measures close to the Harman target (score 67), with bass and treble each within about 0.2 dB of it on average.
Cons: Discontinued, so it is mainly found used. The cable is fixed, so a damaged cord ends its life, and its 2.93 dB spread from the target shows some peaks and dips that a target-level average hides.
