#46 iBasso IT01S: $89.95 Amazon eBay

Pros: A Harman score of 66 in Crinacle’s measurement shows the tuning lands reasonably close to what most listeners prefer. The 16 ohm impedance and 109 dB/mW sensitivity mean a phone can drive it to loud levels. At 8 g per earbud with a 10mm dynamic driver, it is a light, simple wired set.

Cons: Deviation from the target averages 2.84 dB, so the response is not especially smooth. Without an inline microphone it cannot be used for calls, and the KZ PR1 has a higher rating.
