Moondrop Quarks Earphone Closed Anterior Cavity Micro Dynamic Driver IEM Earphone (with mic)

My daily-driver for stage IEMis is the Etymotic ER2SE. Those have excellent passive isolation (i.e., block loud external sound) and have great sound. But they are relatively expensive (~$150). I bought the Moondrop Quarks both as a backup/spare. Pretty often a band-mate might need to borrow a set. BUILD: nice sturdy thick-ish cables. The barrel that holds the eartip is 5.3mm diameter, "lip" that keeps the eartip in place is 6mm diameter and is nice and "sharp" to grip the ear-tip so it won't slip off easily. The housing and fixed cable are appropriately rugged for the price. My set has a mic and some button controls which I don't use or need, but the variant product without the mic is no longer available. The TRRS plug seems to work fine with non-mic TRS-based connections. SOUND: the sound is very good. The bass is neutral and unhyped. There's some extra presence at around 3K which is pretty typical of this type of product. The volume can be dropped way down and the music still feels full and natural. ISOLATION: The passive isolation (i.e., how much they block external sound) is pretty decent. I can't give it a technical number, but my subjective comparison is that the Quarks provide about 75% of the isolation that the ER2SE's do, which is a pleasant surprise-- considering the plastic/resin housing. NOTE: i swapped out the included eartips for triple-flange ones (comparable to what is on the ER2SE)-- for a more fair comparison.

These are fantastic earphones. I got them because of their small profile so that I can wear them to bed and lay on my side without giving myself horrible ear pain. The sound quality is honestly great for the price. I’m no audiophile but so would say they have just as good of sound as wireless earbuds that are easily 3x the price. I find myself reaching for these more often than my iPods now. I don’t generally enjoy earbuds as my ears get itchy with them vs over-ear headphones, but these are very comfortable and I can easily wear them for several hours. I have taken a couple phone calls with these and the sound is good and the person on the other end of the line said I sounded great so long as I held the mic up near my mouth. With the trends going back towards older technology that doesn’t listen in on your conversations or use AI, I would highly recommend these. I have dongles that convert the AUX to USB-C and to Lightning and I keep them in the little bag these earphones come with. I don’t have to worry about battery life or that one of my ear pieces might fall out of my ear and I lose it. There’s no connectivity issues as it’s a direct line to your device. I love these and would recommend them.

I absolutely love this pair of IEM's, and would recommend it to anyone who even wants cheap "earphones". The inline mic is actually quite good. However, with the price there are some compromises. In terms of sound it's great except for the bass, which can't be saved even with higher power and volume. The way the eartips are so tight on the body is kind of concerning (it feels like I'll tear the tips getting them on and off), and the cable works its way loose from the metal clip that anchors it inside each of the monitor bodies over time.

UPDATE update...The microphone stopped working. Purchased July 22, 2022 died August 28, 2022. Beyond return date to Amazon. Durability on this one was poor. Too bad, maybe you will get a better one? I enjoyed the sound and light weight, but they did not last, despite being handled properly. My original five star review stands for the sound, but this is about the durability one month and 6 days since purchase. So one star is fair. Unfortunately, they failed right after the return date and there does not appear to be any other warranty, or way to contact the manufacturer. You could take a chance and buy these and enjoy the sound, or you could end up with a dead pair. My wife asked to borrow a pair of my headphones. Let that sink in.... I had to act. I wanted a decent pair of earphones so my wife would not ask to borrow my nice earphones and break them. I say this with a wealth of experience in lending earphones to wife, and I know you don't want to do that either, so get her a pair of these Quarks and she won't know they are budget ear plugs. I heard good reviews on these and I decided for the price it was great, even if the reviews were hype. The reviews were real and I am very happy with these. The cables are nice and thick and look like they will last. The angled plug and good length for the cable is nice to avoid tangles. The phones are in clear plastic cases that are small and comfortable in the ears. You can lay down with these on and you will be pretty comfortable. They are light weight too. The sound is excellent. For the price or not, the tuning on these is pretty sophisticated, it is pretty flat and balanced. The treble is good, but not too bright and not irritating. The mid range sounds forward and very detailed. The bass is decent and satisfying, but will reach the lowest notes. The bass does sound clean and not boomy. Overall the sound is very balanced with a surprising amount of detail for a single dynamic driver at this price. These are good, inexpensive earphones with a small design that fits well in the ear. I like these for movies, talking and music. You will not regret buying these. The price and sound are awesome.

For the price these earbuds sound pretty decent, stay in my ears, and isolate sound well. Pause/play button works with my iPod, but volume buttons are pretty unreliable. Good for a backup pair of wired earbuds.

Pleasantly surprised by these little guys. None of IEMs would fit under my Shoei X-15 lid without tearing off my ears and straining cables. I was thinking of trying Chu IIs--but for motorcycling, glad I went with these instead since they're considerably smaller. A guy on Reddit recommended Quarks for motorcyclists, and the IEMs are so tiny that don't come into contact with the tight padding. My second concern after size was that these tiny drivers would sound anemic, but that's not the case. They're surprisingly full-sounding with punchy mid-bass and just enough sub-bass to warm up the tuning. I give them a little bass boost on my Apple Music app, or with my Qudelix EQ, and EDM/hip hop sounds fine. No sibilance or shoutiness. Quarks aren't going to be bass cannons, obviously, but they're punchy and deceptively outperform for their size. Good headroom, too. Also ideal for listening in bed. You decide on insertion depth and can control this with tip choice, but Qarks can be inserted very deep if you wear a helmet. With Comply foam tips, these things have THE best isolation of all my IEMs. Almost too good. My bike is loud, and I can barely hear anything. Nitpicks: I'd prefer a no-mic version, as well as a straight plug over a right-angle. Not a big deal. Bottom line, they offer surprisingly good sound quality, isolation, and convenience, and when you factor in the price, they're an easy 5 stars. Would recommend.

Awesome, very happy. They are tiny, but the sound quality is awesome, especially considering the price and size. Yes, there is not much bass, but they don't have 10 inch woofer obviously. Very happy: size, value and quality.

They sound great for the price but broke within a week of use. The right ear no longer plays any music. Tried my other IEMs with the source and they all worked fine. I can’t recommend them due to how insanely flimsy they are.

Jag fick köpa ett extra par då min flickvän beslagtog mitt första. Detta är utan tvekan de mest prisvärda IEM:s som finns. Låter minst lika bra som IEM:s som kostar uppemot 100 euros. Väldigt balanserad, detaljrikt och naturligt ljud. Inte V-formade dock, så om man är väldigt inne på 3tt V-format ljud är dessa kanske inte för dig. Men vill man ha neutralt och klart ljud slår dessa aldrig fel. Rekomenderar att använda dessa med Moondrops spring tips.

good sound and good value earbuds. use these with my iPod and I'm satisfied

Nothing to really dislike about these earphones, clear, loud and honestly you get your moneys worth, I recommend these for people who want good quality earphones without spending too much money

Vorab ich war auf der Suche nach einfachen indias mit Mikrofon als Alternative zu meinem High end Kopfhörern. Mit den Moondrop Quarks bin ich definitiv fündig geworden. -Verarbeitung: Die Kopfhörer machen einen sehr guten Eindruck das Kabel ist stabil, auch das Design ist schick. Das Kabel lässt sich leider nicht abnehmen was aber bei dem Preis vollkommen okay ist. -Klang: Der Sound ist grundlegend als solide zu bezeichnen. Ein großteil der Musik spielt sich in den Mitten ab, die Auflösung in den Höhen könnte deutlich besser sein. Der Tiefgang bei den Bässen ist vorhanden geht aber für meinen Geschmack nicht aufgelöst genug runter. In Summe ist der Klang aber okay da der Bass nicht wie bei anderen günstigen Kopfhörern dominiert und das Klangbild verzerrt. Als direkten Konkurrent würde ich von Moondrop die Chus sehen, welche Klang besser sind aber von der Qualität nicht so langlebig. Die Kritik am Sound ist aber ein wenig unfair, da ich diese mit High End inears vergleiche (etymotic er4xr, shure se535, dt770) -Fazit: Als Bürokopfhörer zum Telefonieren sowie gelegentliches Musik hören vollkommen ausreichend und preis-leistungstechnisch uneingeschränkt empfehlenswert. Wer den Vergleich mit Highend Kopfhörer nicht hat wird hier auch erstmal nichts vermissen.

Por menos de 20€ é difícil arranjar uns IEM's com melhor qualidade. O microfone tem óptima qualidade para chamadas. O som é bastante bom para o preço, não há um foco excessivo nos graves e a separação de instrumentos e aceitável. ainda traz uma pequena bolsa de transporte.
