Youtube Video Summary
Priced around $1,350, the Dunu Glacier is a premium nine-driver tribrid IEM featuring one dynamic driver, four balanced armatures, and four electrostatic drivers. The build quality is exceptional with a beautiful mirrored polished steel shell, though it's noted as a bit large, heavy, and a fingerprint magnet. Comfort is generally good, and it includes a high-quality, pliable cable with interchangeable connectors and a secure chin slider. Packaging is also highlighted as exceedingly well done, typical of Dunu's recent standards.
Sonically, the Glacier delivers a very bassy, extremely fun, and highly engaging V-shaped signature. The strong bass is balanced by prominent upper mids, offering good detail resolution and micro-details. However, a noticeable energy peak around 3kHz can make some tracks feel overly energetic, intimate, or even slightly shouty, limiting its versatility for mellower listening sessions. Comparisons place it near sets like the LETSHUOER Tera (less bass, cleaner) and ThieAudio Monarch MK I (less bass, more even upper mids), while noting it surpasses the Dunu Brain Dance (DK-31) in detail and bombast, though the Brain Dance offers significant value at half the price.
Ultimately, the Dunu Glacier stands out as a fantastic and unique IEM with satisfying bass weight, good imaging, and excellent micro-details. Its fun, bombastic character and high-quality build make it a compelling choice, but the specific upper-mid energy requires careful consideration. It earns a recommendation for those seeking an ultra-engaging Harman-style listen with top-tier driver tech, though demoing is advised due to its distinct tonal quirks.

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:
