Not a hardcore audiophile. Received my product yesterday and let it burn in the whole night. This morning during my testing, found the sound quality quite good(way better than normal budget jbl/boAt but seemed similar to my earlier RHA MA390). Build quality is decent, although not as good as my RHA but decent for the price. Used it normally with my mobile/Laptop headphone jack(without amp) and sound output was quite good and loud. The only issue is that the mic and the 2 volume buttons(including the play/pause function) doesn't work on Android 12 and Windows 10 and Windows 11; hence can't take any calls- tried to take call and the caller complained nothing was audible from my end. Tried it with my parent's android 11 phone and everything works fine there. My RHA and friend's JBLs work fine in these devices with play/pause and volume functionality. Not sure only my piece is defective or all the quarks have the same quirks. Have raised a ticket with hz team and will wait for their confirmation on the same.

I wasn't expecting such a rich sound from such a small driver unit. Without burn in also, the sound is awesome. Highly recommended. And that comfort...OMG

A good audiophile product to begin with and elevate the listening experience from average earphones. Well balanced sound output and details with low frequencies are well captured. The bass could have been improved though. Overall it gives a soothing listening experience cancelling the noise. Thanks to Headphone zone for bringing the products with detailed description which helps during purchase and technical assessment.

Alright, I am not some audiophile and I do not have the ears or the necessary equipment to distinguish, that being said what I am is just a guy who loves songs and want to get the most out of it.

Design | Comfort
It's a pretty small earphone made out of transparent plastic shell. They look fine to me. But their small size makes it really comfortable in ears I often have to check my ears to make sure they are there. It kind of vanishes in the background and there's no fatigue even after prolonged season. The cable doesn't fit the aesthetic of the earphone but can't ask for more. Also since they are made of plastic your durability may vary.

Now the most important part: The sound
It has a very relaxed warm laid back and neutral sound. Decent bass if your playlist contains lot of bass or edm you may skip this. But for those who like more vocals and instrumentals like pop or jazz oh boi this feels freaking good.

You might need to feed it a bit more power hence a dac is preferred.

And you must try it with Wavelet app that app really takes this pair of earphone a whole new level it fixed some of the noise and made it way too good.

Having a microphone is nice, and it has a decent microphone overall a great purchase for casual listening movies calls and just about day to day usage if your budget is tight look no further

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

The sole reason I bought the Quarks was as a stand-in pair during commutes. I really didn't feel like treating my Tin T2+ roughly ;). As such, I wasn't expecting much. When I first held them they felt deceivingly tiny yet durable. Despite the plastic shell, the housings feel solidly built. The wire has a bit of memory but is thick and would not wear easily.
Now coming to sound, I wasn't expecting them to sound as amazing as they do. The tonality is fairly accurate and the details are mostly there. Even the soundstage is unbelievably wide despite their size. Even though the T2+ fare better in tonality and detail the Quarks still surpass them in soundstage depth and width. This is nothing short of amazing considering those go for 4 times the price of the Quarks.
Overall the Quarks are a must if you want to try what good audio sounds like!
And Kudos to Headphonezone for quick shipping and thanks for the lovely playlist cards, Now I got even more songs to add to my playlist. It was a nice experience :)

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.

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%

Comfortable to wear for longer hours, best for podcast, light weight, good for work from home if you are listening to music with work

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..!!

I actually hated the cable. Cable is too bad that it ruins the whole experience. But loved the sound output. I have always used Sennheiser cx180 but those are now hard to find so I bought an alternative to that. The sound was similar but lacked a bit of bass which is expected because of the balanced sound profile. Loved the sound and transparent design...but disgusting cable.

Moondrop never disappoints, this one is an entry level iem and it's ideal for someone who likes small driver setup, compact design, lightweight and easy on the ear iem's. Sound clarity is awesome and it will be better if you pair it with a dac amp as the output is slightly less. Overall this is a nice product for the cost and can add this to the collection.
