Found the Monarch MKIV physically huge, the worst ergonomics they've had, consistently making their ears swell; the sound and bass are top notch, close to the Mysticraft Myth for gaming.

“Ergonomics-wise, it’s the worst. Made my ears swell consistently. Sound-wise, pretty much exactly what you’d want; but the myth is still slightly better for gaming.”
