Short answer: the Moondrop Horizon. It ranks #326 of 481 over-ear headphones by sound quality, rated 3.1/5, at $199.99. The Beyerdynamic MMX150 ranks #365, rated 2.9/5, at $189.99, $10 cheaper, not enough of a saving to outweigh the sound-quality gap.
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.
The case for the Beyerdynamic MMX150: Bass is lifted about 3.7 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: A 5.9 dB peak near 6.7 kHz can make cymbals and sibilance sound sharp.
Buy the Moondrop Horizon. It is rated higher for sound quality, and the $10 saving on the Beyerdynamic MMX150 is not enough to make up the difference.
