#45 Whizzer HE01: $45.00 Amazon eBay
Pros: Crinacle’s measurement gives a Harman preference score of 66, which puts the tuning in decent territory for a budget in-ear. The 18 ohm impedance and 112 dB/mW sensitivity make it easy to drive from a phone or dongle without an amp. A single dynamic driver and a slightly warm tilt suit relaxed, bass-forward listening.
Cons: The response is uneven, with a standard deviation of 2.78 dB around the target, so some instruments will sound tonally off. There is no built-in microphone, so it only works for music and not for calls.
