#658 SoundPEATS Free2 Classic TWS Discontinued eBay
Pros: Budget true wireless earbuds with about 8 hours per charge and 30 hours with the case. It measures reasonably close to the Harman target (score 68 across three measurements).
Cons: Discontinued, so it is mainly found used. Treble sits about 5.3 dB below target, a dark, relaxed balance. Sub-bass falls about 3.2 dB short at 30 Hz. A 2.71 dB spread from the target shows peaks and dips that better tuned sets avoid. Its score rests on three measurements.

Frequency Response
How the SoundPEATS Free2 Classic 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 the median of 3 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 3 measurements from the squig.link databases of dhrme, hobbytalk and vortexreviews. Thanks to each of them for publishing their work.
