Moondrop Quark 2 offers excellent isolation, clean balanced tuning and strong value from its built in USB C DAC at around 17 USD, though bass slam and overall technical performance remain a step behind the Moondrop Chu II. Outstanding isolation, comfortable ultra light shells and durable USB C cable with integrated DAC and mic at a very low price. Bass impact and overall technical performance are clearly weaker than on the Moondrop Chu II and the fixed cable and strong seal may not suit all listeners.
Youtube Video Summary

Moondrop Quark 2 is a very affordable pair of IEMs around 17 USD that focuses on practicality, combining a fixed USB C cable with an integrated DAC, mic and simple bullet shaped shells. Build feels surprisingly solid for the price, with a sturdy USB C plug that inspires confidence and a light, comfortable fit that can be worn straight down or over ear. Isolation is a major highlight: the seal is so strong that office noise, fans and even mechanical keyboard clatter are largely blocked out, making this a compelling option for commuting or noisy environments, although potential pressure build up should be kept in mind for sensitive users.

On the tuning side Quark 2 delivers a smooth and safe response with a sub bass focused lift that keeps the low end clean but on the lighter side, so bass quantity and slam will not satisfy those who want a heavy hitting presentation. Midrange is the clear star, with male and female vocals rendered cleanly and without shout or harshness, helped by controlled bass and relaxed upper treble that let voices sit a little forward in the mix. Treble provides enough energy to prevent the sound from becoming dark and cymbals and high frequency instruments are present without sibilance, but extension, air and sparkle are modest, giving an overall character that is more relaxed and easygoing than bright and exciting.

From a technical standpoint Quark 2 is solid for its price but not a detail monster, with detail retrieval and dynamics sitting around average, an average to slightly below average stage and imaging that still places sounds clearly to the left and right. For budget listeners the mix of clean tonality, good channel matching and the integrated USB C DAC makes the overall sound quality feel excellent at the price, yet when compared directly to the Moondrop Chu II the Quark 2 reaches only around sixty to seventy percent of its performance in bass impact, naturalness, separation and micro detail. Quark 2 clearly wins on cost, isolation, comfort and cable durability, while Chu II still takes the lead for pure sound quality, versatility and accessories, so the better choice depends on whether maximum isolation and convenience or higher technical performance matter more.

Ultra budget Moondrop Quark 2 focuses on clear, forward vocals with natural upper mids, but bass and treble are on the lighter side and it trails the strongest sub-$30 rivals. Very affordable vocal focused tuning with natural upper mids, clean bass and useful USB C and inline microphone convenience for everyday use. Light bass, relaxed treble and average technical performance make the Quark 2 less engaging than many competing ultra budget sets and not ideal for listeners who want strong impact or sparkle.
Youtube Video Summary

The Moondrop Quark 2 is an ultra budget in ear monitor that comes in around 17 dollars and focuses on practicality and convenience as much as sound. The tiny bullet style shells are easy to wear, the materials feel simple but sturdy enough for daily use, and the built in microphone and USB C termination make it a grab and go option that hobbyists can toss in a bag without worry. At this price it already brings a sense of value before any music starts.

Sonically the tuning leans toward a neutral signature with mid range forwardness, putting vocals and instruments front and center while bass and treble sit slightly in the background. Upper mids are shaped in a way that makes voices and many instruments sound fairly natural, but the lower mids and mid bass sit below a more typical preference, which can leave notes a little thin and lacking weight. Sub bass is emphasized more than mid bass, keeping things clean and avoiding bleed into the mids, yet the overall bass level is still lighter than ideal and does not fully balance the upper mid energy.

The top end has enough treble presence to hear cymbals and higher frequency information, but there is not a lot of shimmer, sparkle or air, so extension and micro detail are limited and the presentation stays on the relaxed side. Technical performance is about what can be expected at this price, with some detail and a stage that is not wide but also not overly intimate. While several rivals like the Chu, Waner and especially the Celest Wyvern Abyss offer a tuning that lines up closer with a typical preference for bass and treble, the Quark 2 still makes sense for vocal focused listeners who value its tidy form factor, built in features and are happy with a slightly leaner and more easygoing sound for seventeen dollars.

Bass C+
It delivers adequate punch and texture, though nothing stands out. Sub-bass presence is hinted rather than delivered.
Mids B
It offers engaging mid frequencies with pleasing clarity and layering. Details emerge without becoming harsh.
Treble C+
Expect a polite treble presentation that balances presence with restraint. Percussion carries a pleasant sparkle.
Dynamics C+
Expect solid impact overall, even if finer gradations feel a touch smoothed. Micro-details could still be sharper.
Soundstage C+
It creates a serviceable arc that keeps instruments apart but rarely draws you into the space. It sounds more intimate than expansive.
Details C+
It rides the line between musicality and analysis, occasionally letting micro-detail slip by. Complex mixes stay organized for the most part.
Imaging B-
Complex mixes stay organized thanks to the improved spatial discipline. Complex passages stay intelligible.
Gaming B-
Moderate spatial presentation conveys general directionality. Suitable for casual play where precision isn't critical.
