Measured tuning, side by side
Both curves are real community measurements (gold: musicteck · blue: Sennheiser). Each is level-aligned to its own 200 Hz–1 kHz mean, so rig offsets don't skew the comparison.
musicteckSennheiser
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.

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.
