Every tracked fact about the two, side by side - prices, history lows, ratings and measured tuning. No verdict: which one to buy is the visitor's decision, always.
Both sides are in-ear monitors. The rows below are the facts each store publishes for this shelf - driver arrangement, impedance, sensitivity, plug and connectivity. A dash means the listing does not state that spec.

Measured tuning, side by side
Both curves are real community measurements (gold: aful · blue: ThieAudio). Each is level-aligned to its own 200 Hz–1 kHz mean, so rig offsets don't skew the comparison.
afulThieAudio
Average level per band, relative to that curve's own 200 Hz–1 kHz middle - a taller bar plays louder there on the measured files. Same colours as the chart above.
Wearing your own earphones or headphones? Pick them here and the player pre-corrects for their sound, so the demo plays the target tuning itself - not both mixed together.
Same signal through both tunings at once - slide to blend. Start on pink noise for the clearest read.
Tuning distance±1.42 dB RMS91% match - Very close. Computed on a shared 40-point log grid, 20 Hz–10 kHz. A measurement-space fact, not a promise two ears agree.
Bass · 20–250 Hzaful +0.2 dBAverage level difference in this band, both curves aligned to their own 200 Hz–1 kHz mean. Plus means aful plays louder there on the measured files; minus means ThieAudio does.
Mids · 250–2,000 Hzaful −0.1 dBAverage level difference in this band, both curves aligned to their own 200 Hz–1 kHz mean. Plus means aful plays louder there on the measured files; minus means ThieAudio does.
Treble · 2,000–10,000 Hzaful −2.0 dBAverage level difference in this band, both curves aligned to their own 200 Hz–1 kHz mean. Plus means aful plays louder there on the measured files; minus means ThieAudio does.
What a curve cannot seeBuild, driver QC unit-to-unit, comfort, isolation, accessories, warranty and resale value sit outside the graph - usually what the pricier one is charging for.
