#243 SuperTFZ Force King: $129 eBay
Pros: An 11.4 mm graphene dynamic IEM at about $129 with a preference score of 78. Bass reaches 20 Hz with a slight lift, and the aluminum and crystal glass shell weighs 5.8 g per side.
Cons: The tuning is bright and forward, with peaks of 6.7 dB near 10.9 kHz, 5.5 dB near 4.9 kHz and 4.3 dB near 2.3 kHz, so it can sound shouty at high volume. It is sold out, and the score rests on a single measurement.
Is the SuperTFZ Force King right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 78).
- you want sub-bass rumble that reaches down to 20 Hz.
Skip it if
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $95 less.

Frequency Response
How the SuperTFZ Force King 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 cqtek. Thanks to them for publishing their work.
