#511 Kenwood Glass Core: $199.95 Wireless Amazon $199.95 eBay
Pros: ANC earbuds with a 10 mm glass diaphragm driver at about $200, with LDAC, Bluetooth 6.0, multipoint and 13 hours with ANC, and a preference score of 74. The midrange stays within about 1 dB of target with a warm upper bass lift.
Cons: An 8.2 dB peak near 8.2 kHz adds sibilance while presence is 2.5 dB low, and sub bass is 2.7 dB light. It matches the Kenwood Glass Core Pro on rating for far less, but the score rests on a single measurement.

Frequency Response
How the Kenwood Glass Core 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.
