Dan Clark Audio Aeon Flow Closed - ranked #139 of 454 Over-Ear Headphones · Editor's rating 3.9/5

#139 Dan Clark Audio Aeon Flow Closed: $799 Discontinued eBay

Pros: One of the best-measuring closed-backs, with a Harman score of 79 and a tight 2.12 dB spread from the target, plus a light 340 g foldable build.

Cons: Discontinued and replaced by the Dan Clark Audio Aeon RT Closed, so it is mainly found used. Treble runs about 2.6 dB below target, slightly dark, and the planar driver wants a desktop amplifier. See headphone amps and DACs with enough power to drive it.
