#20 Stax SR-L300: $455.00 Audio46 eBay

Pros: An excellent preference score of 89 in crinacle’s measurement, among the closest tunings to the Harman target in its class. The open back push-pull electrostatic driver gives a wide, airy presentation, and at 323 g it is light for a full size headphone.

Cons: As an electrostatic headphone it needs a dedicated Stax-compatible energizer to run at all, which adds real cost and a box on the desk. The open back leaks sound and blocks no outside noise. The Beyerdynamic DT 900 Pro X shares the same rating for less money and plugs into ordinary gear.
