Short answer: the Fostex T40RP Mk3. It ranks #317 of 481 over-ear headphones by sound quality, rated 3.2/5, at $189.99; the Moondrop Horizon ranks #326, rated 3.1/5, and costs $199.99, which makes this an easy call rather than a real tradeoff.
Why pick the Fostex T40RP Mk3: This closed back planar magnetic model measures smoothly in oratory1990’s test, with only 2.57 dB of deviation around the target and sub-bass within 6 dB down to 20 Hz. The tradeoff: Sensitivity of 91 dB/mW is low for an over-ear, so a dedicated headphone amp helps it reach full volume.
Why pick the Moondrop Horizon: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The catch: Presence sits about 3.4 dB low with a 14.6 dB dip near 10.6 kHz, so vocals and instruments lose some bite.
Buy the Fostex T40RP Mk3. It is rated higher for sound quality than the Moondrop Horizon and costs less, so only choose the other one for a particular feature it does better.
