#52 Sennheiser IE 900: $1,299.95 Amazon eBay

Pros: Oratory1990 measured sub-bass and bass within about 1.2 dB of target, so the low end is tidy and controlled. Sensitivity of 123 dB SPL/V and a 16 ohm impedance make it easy to drive from a phone, and the 7mm dynamic driver is rated to reach from 5 Hz to 48 kHz. Top-octave air sits about 3.6 dB above target for an open, detailed treble.

Cons: Presence from 3 to 6 kHz is about 6.7 dB below the Harman target, with an 8.8 dB dip near 3.6 kHz, which recesses vocals and removes some bite. A preference score of 63 is modest for such a premium product, and the HIFIMAN RE2000 has a higher rating at a lower price.
