#512 Kenwood Glass Core Pro: $429.95 Wireless Amazon $429.95 eBay
Pros: Flagship ANC earbuds at about $430 with a bi amped glass diaphragm driver plus MEMS tweeter, adaptive ANC, LDAC, wireless charging and 12 hours with ANC, and a preference score of 74. The midrange stays within about 1 dB of target.
Cons: Sub bass is 5.6 dB below target, so the low end lacks weight, and a 6.0 dB peak near 8.2 kHz next to a 4.8 dB dip near 9.4 kHz makes treble uneven. It rates the same as the cheaper Kenwood Glass Core, and the score rests on a single measurement.

Frequency Response
How the Kenwood Glass Core Pro 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 aden. Thanks to them for publishing their work.
