#632 TANGZU Princess Changle Discontinued eBay
Pros: A bullet style earphone with a 6mm dynamic driver and a fixed cable. Measurements show full sub-bass to 20 Hz (score 68 across six measurements).
Cons: Discontinued, so it is mainly found used. Bass sits about 3.0 dB above target, a bass heavy balance. A low 95.5 dB sensitivity needs more volume than most IEMs.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the TANGZU Princess Changle 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 6 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 6 measurements from the squig.link databases of aftersound, bakkwatan, hbb, ianfann, pw and therollo9. Thanks to each of them for publishing their work.
