The Monarch MKIII sits firmly in flagship IEM territory, and A$1,150 for a like new pair is a bit ambitious rather than a bargain. The current new price is about A$1,530, so this ask is only a moderate discount and still above what I’d want to pay for a used set unless it’s exceptionally complete or barely touched.
It’s still a compelling listen: the MKIII is known for a clean, natural, highly detailed tuning with strong sub-bass and a very monitor-like presentation, plus the full accessory package with a modular cable and 2-pin fit. If the tips, cable, and case are all present and the shells are truly pristine, this is a serious endgame-style buy — just not one I’d call especially sharp at this price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Thieaudio emerged from a tight-knit group of DIY audio enthusiasts, evolving into a prominent player in the in-ear monitor (IEM) market without a single founding year or named founder tied to its official origin. Backed by an international team of engineers primarily from China and South Korea, the brand channels a passion for high-fidelity sound that resonates deeply within global audiophile circles.
The company specializes in premium IEMs and headphones, renowned for innovative driver configurations like the quadbrid setup in its flagship Origin model—combining one dynamic driver, four balanced armatures, two electrostatic drivers, and a bone conduction unit for enhanced bass, precise mids, and natural treble. Handcrafted with top-tier materials and custom cables, Thieaudio products prioritize technical excellence and immersive listening over traditional categories such as speakers or amplifiers.
Positioned as a mid-to-high-end niche boutique in the portable audio segment, Thieaudio commands respect for its best-in-class tunings, superb performance, and accessible pricing under $1,000, making it a go-to for discerning bass enthusiasts and critical listeners seeking refined, budget-friendly excellence in a crowded market.
