#160 iBasso SR1: $399.00 Amazon eBay
Pros: A low 22 ohm impedance means the 50 mm dynamic driver runs from a phone or laptop without a separate amp. Its very warm tilt can appeal to listeners who want a dark, bass-heavy sound and dislike any brightness.
Cons: Crinacle’s measurement gives it a preference score of only 25, with a steep warm tilt and large deviations of about 4.5 dB on average from the Harman target, so most listeners will hear a muffled, uneven balance. The semi-open back leaks sound and lets outside noise in, and the cheaper Sony WH-1000XM5 rates noticeably higher.
