You're new to the audiophile world and listened to Boat Bluetooth headphones all your life, and now realizing that you've missed so much ? Yes, you can buy this headphone your eyes closed.

You are audiophile ? have expensive IEMs Portable DAC&AMP and scared to use it outside 'cause of sweat and rain? or are you scared that someone will steal your IEM in local train? Yes you can buy this.

You know audio(studied audio on the internet) and yet it's your first purchase, though don't have any DAC&AMP. Please don't buy this, this IEM is very very amp depended, it opens like a butterfly when amped. Unless you have at least Apple 3.5mm Dongle [Yes it is a DAC&AMP] , you can train your ears with less expensive earphones like Audio Technica CLR100.

Recommendations aside, this is a gem. Clear like Elon Musk at only 999/-. Subass is there and you can hear it slightly. Bass is there and it is fast & controlled. Decay is Outstanding for its price. The soundstage is okay too but imaging is good and quite accurate. The treble sparkliness isn't there, though it is airy and present but this IEM is nowhere bright.

Midrange is the focus here, female vocals sounds very realistic, male vocals are not as good as female but still impressive. Instrument separations and speed is good enough.

Recommended 100%

- vocal focused tuning
- decent bass punch and extension
- smooth balanced treble
- superb fit and ergonomics
- decent timbre

Update
Yes it's sounds good and ok for the price we paid.,for comfort this is the best

At this budget you can't get this kind of clean sound , but you should equalise properly

Note : If you are buying this for your daily usage and you are rough user ...please think twice ., And also if u like boomy bass go 4 kz edx pro

If you are coming from a sub 1000 rupee cheap iem, look no further. This will step up your ear to start understanding what a hi-fidelity, tuned, well balanced iem will sound like. In short, this is a Bang for Buck buy and a gateway drug to your audiophile journey!

Now let me get into the audiophile shoes and use appropriate terms. Out of the box it is lacking in sub bass and is a tad muted in the upper mid range. It not at all shouty like its counterparts in the same price bracket! Burn the iem in for atleast 40hrs to get its actual sound signature. For the uninitated do a google search to understand this initiation ceremony!

Yes it is tuned to harman curves which, to the new Audiophile(because you become one when you buy this) means it would sound neutral and relaxing. It will scale well with a dedicated dac/amp like a Fiio btr3k rather than your phone's output or laptops headphone out. That is you will start hearing more separation of sounds in your music. You will hear things like finger twangs on the a guitar fret board or the breath intake of the singer etc.. That will change how you appreciate music.

It is an all plastic but well built unit for the price. Moondrop has invested more into the sound than the build. To me, it looks like it can take the stress of normal use as an everyday iem. I would recommend to use 3rd party eartips like the Spinfits or complys to get the most comfort and listening pleasure. Out of the box silicon tips are substandard and you may find it not fitting well into your ears.

Now strap on and get ready for the ride, Good luck!

A well balanced and neutral sound signature. Not the musical tuning but closer to harman tuning. But at this price there's nothing to complain except the cable which kinda sucks. Go for it, you won't find this kind of sound under rs 1000.

It's a bang for buck product. I bought this for watching movies, video, and for some casual listening. i would say they have very good vocal which are well tuned by moondrop as without any sibilance. One star less due to the bass, its not that punchy or something hits your chest at every drops and while watching movies there slight experience is missing but they are very good for the speeches and details. For music listening its good to. They can easily powered by regular smartphone yet a dedicated DAC/AMP helps for its fullest potential. They are very balanced so if you are a bass head look for something else. I am happy with my purchase, thanks to Headphone zone..!!

It's been 2 weeks since I have purchased the Moondrop Quarks from Headphonezone as of writing the review.
The quarks sound way better than generic earphones that you get from your smartphones even without using any Dac-amp or DAP. I do not have any of those so I wrote the review simply by testing it with smartphones.

I would describe the sound signature of quarks as kind of neutral. This IEM is smaller than I expected with good comfort. I don't recommend this IEM if you are a basshead because the bass may not be as punchy, energetic or impactful as you may expect, especially comparing it directly with generic earphones.But the thing is the bass is fast, tight and overall better quality. The female vocals sound good.To me, the male vocals are kind of -meh.Treble is present and in adequate amount considering the price. Technicalities are average.

Will I recommend this IEM? -

Absolutely yes, if your budget is strictly under 1K and you want a neutral sounding IEM with good sound quality for the price.

If you know how to EQ your earphones to your tastes then you can't find a better deal, after EQing and using it with HeSuVi this has the fastest treble I have ever found! These are very light and comfortable, I could use them all day! Noise isolation is also very good.
