Elevated, well-textured mid-bass. Pleasant mids. Elevated upper-treble may be pesky to some.

Reviewer Score
Better low-end texture and overall more engaging than MK2, but lacks the mid-range/vocal magic, so depending on your preference either is great. Still TOTL tech like MK2. Great all-rounder. Jays Audio Youtube Channel

Still perplexingly poor bass performance, but improves upon the Monarch MKII's treble extension noticeably. Precogvision Youtube Channel

I prefer the Monarch MK II for its tonality, vocals, and timbre, but I get why some prefer the MK III. More bass, treble, and detail than the Monarch MK II. The vocal magic of the Monarch MK II is gone.Gizaudio Axel original ranking

Better bass response compared to the mk2 Trades off the lush midrange in place of a cleaner sounding, almost boring midrange

7.1
Reviewer Score
An improvement in the bass and treble department over the Mk2, but without the same special sauce in the mid-range and with some imaging problems still.
