#290 Bose SoundTrue Ultra: $149.95 Discontinued eBay
Pros: A wired earbud with StayHear Ultra tips and an inline three button remote, scoring 77. Bass is full to 20 Hz with a warm 3.6 dB upper bass lift that makes it sound rich rather than thin.
Cons: Discontinued, so it is mostly found used or renewed. A 5.9 dB peak near 10.9 kHz adds some treble edge, Bose never published driver or impedance specs, and the score rests on a single measurement.

Frequency Response
How the Bose SoundTrue Ultra measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of hu-fi. Thanks to them for publishing their work.
