Headphone Ranking

Headphones ranked by Harman headphone listener preference scores.

Tables include the preference score (Score), standard deviation of the error (STD), slope of the logarithimc regression fit of the error (Slope) for both headphone types and average of the absolute error (Average) for in-ear headphones. STD tells how much the headphone deviates from neutral and slope tells if the headphone is warm (< 0) or bright (> 0).

Keep in mind that these numbers are calculated with deviations from Harman targets. The linked results use different levels of bass boost so the slope numbers here won't match the error curves you see in the linked results.

Over-ear table includes headphones measured by oratory1990 and Crinacle using GRAS systems. Measurements from other databases and systems are not included because they are not compatible with measurements, targets and preference scoring developed by Sean Olive et al.
