#759 7Hz x Crinacle Diablo: $159.00 Amazon $159.00 eBay

Pros: The single 14.5mm planar driver holds its output down to 20 Hz, sitting about 1 dB above target at 30 Hz, so deep synth lines and kick drums keep their weight. Its tuning best suits listeners who want a warm, bass-forward sound, with bass running about 4.7 dB above the Harman target. At 18 ohms and 107 dB/V it plays loud from a phone or a basic dongle without a separate amp.

Cons: Across 16 hobbyist measurements it earns a preference score of only 56, with a 7 dB dip near 6.3 kHz and presence about 3 dB shy of target that dull vocals, guitars and cymbal attack. The extra 2 dB in the low mids adds thickness that can blur busy mixes. Similarly priced rivals such as the Etymotic ER3XR and Kefine Arnar are rated higher.
