Youtube Video Summary
Premium build with a large, Monarch-like shell that sits extremely comfortably, accented by subtle blue flecks and a secure nozzle lip. The bundled 4.4mm cable feels upscale, while the case and tips are serviceable. There’s noted pricing controversy—an initial teaser around $1,000 for a handful of units before settling near $1,600—but the product itself presents as a polished, high-value package.
Sonically, this is a strong, impactful bass tuning with rich warmth that never smothers the mids. Female vocals pop, instrumentals sound lifelike, and earlier worries about a dark treble prove overstated; the tonal balance feels right and cohesive. Sub-bass digs deep, mid-bass hits with authority, and the overall presentation is sweet, engaging, and musical—the sort of set that invites long sessions without fatigue. It comes across as a top-tier collaboration with a crowd-pleasing signature for bass lovers who still care about clarity and timbre.
In comparisons, Dunu’s Mirai reads brighter and leaner with issues like hiss and channel imbalance on the sample heard, scoring around “three stars,” while Jupiter earns a decisive “five-star” nod. Against heavy hitters like Elysian Annihilator and Grand Maestro, those sets feel more resolute, but Jupiter is more fun, with a richer, sweeter tonality. Versus Fatfreq Scarlet Mini, Jupiter offers just-right bass (rolling off warmth around ~200 Hz) rather than excess. The conclusion is emphatic: a 9.04/10, described as a “love letter” to bassheads and one of the finest pure basshead tunings heard—highly recommended, especially if a second-hand deal brings the price closer to earth.

Youtube Video Summary
Priced between $1,150 and $1,300 depending on custom faceplate options like the butterfly design shown, the Thieaudio Monarch MK IV boasts exceptional build quality with a large but well-contoured titanium shell offering a secure and comfortable fit. Key features include the innovative rumble switch for adjustable bass levels on the fly, a durable two-pin connector, and a solid feel that inspires confidence in longevity. While the included accessories are considered fair but unexciting, the shell's customization potential and rugged construction are major highlights.
Sonically, the Monarch MK IV delivers a detailed, exciting, and clean sound signature that stands as the best in the Monarch lineage. The rumble switch provides two distinct profiles: the red switch (no rumble) offers a balanced, tactful bass presentation, while the gold switch (rumble) adds a satisfying sub-bass shelf ideal for genres like hip-hop. Treble performance is notably improved over the MK III, though a 10k peak requires careful ear tip selection for some listeners. It trades blows with flagships like the $3,000 Annihilator (better sub-bass focus) and the $1,800 Elysian Apostle (more vocal forward), often matching or exceeding their technicalities while offering its unique tuning flexibility.
Scoring a top-tier 9.8, the Monarch MK IV earns its place through a compelling combination of premium build, the highly functional rumble switch, and outstanding sound quality that feels both special and refined. While acknowledging the high price, it represents significant value against competitors like the $2,000 Thieaudio Valhalla or the fiddly Grand Maestro, offering a feature-rich, durable, and sonically excellent package that justifies its position as a current summit-fi favorite.

Pros
I don't regret buying those. I would not describe them as a huge upgrade to the Mk3 in terms of sound, but it is noticeable. Built quality and overall experience much more premium than MK3.Cons
The designs of the shells are a matter of taste.Find your next IEM:
