#169 Devialet Gemini II: $499.00 TWS Amazon $499.00 eBay
Pros: ANC earbuds with aptX, AAC and IPX4 whose sub bass, bass and lower mids sit about 1.5 dB above target for a full, warm sound. Deviation from target is a low 1.65 dB.
Cons: An 8.5 dB peak near 8.2 kHz can make sibilants sharp, and battery life is short at 5 hours, 22 with the case. The Moondrop Golden Ages 2 rates higher for far less, and the score rests on a single measurement.

Frequency Response
How the Devialet Gemini II 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 dhrme. Thanks to them for publishing their work.
