Thieaudio Monarch MK3 Reviews
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
Fatiging at times for me, too fun at times. Jaytiss Youtube Channel
Better bass response compared to the mk2 Trades off the lush midrange in place of a cleaner sounding, almost boring midrange
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

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

2025-08-14MK2 but more fun and more V-shape Not as natural in timbre Tim Tuned Youtube Channel
Still perplexingly poor bass performance, but improves upon the Monarch MKII's treble extension noticeably. Precogvision Youtube Channel
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.
Thieaudio Origin Reviews
Best bassy set under $1K. Bassy/thicker meta tuning. You can actually feel the reverb and vibration from the bone conduction drivers, great control and low-end texture. Mids and treble are also well extended with no major issues, although it can get sharp at times with the snares/electronic stuff ie, past 3:30 on Time by Hikaru Utada. Jays Audio Youtube Channel
Great set, has a lot of positives and is amazing on bass tracks. Jaytiss Youtube Channel
Mega bass additiveness Bass too much Tim Tuned Youtube Channel
Interesting sound. It becomes it's own thing. Fit is not great.Super* Review original ranking

The Thieaudio Origin delivers a bass-forward signature with a substantial 12dB sub-bass boost that provides visceral rumble and slam, particularly effective for electronic or hip-hop genres. Despite this emphasis, the neutral midrange avoids bloat, preserving vocal clarity and instrument separation, while the electrostatic drivers contribute a smooth, airy treble free from harshness or sibilance. Its technical performance is strong, offering a wide, holographic stage and precise imaging, though micro-detail retrieval falls slightly short of some competitors in its price tier.
Comfort is divisive due to the large shells, which may cause fatigue or fit issues for those with smaller ears, necessitating careful tip selection for optimal seal. The package includes a high-quality modular cable with swappable terminations (3.5mm/4.4mm) and a distinctive round Alcantara case, though the included ear tips may not suit all users.
