Powerful Composite Magnetic Micro Diaphragm Dynamic Driver

Quarks adopts a 6mm diameter miniature external magnetic circuit architecture diaphragm dynamic driver, and an external magnetic circuit composed of high-performance neodymium magnets and magnetic conductive parts, which can provide excellent dynamics, lower nonlinear distortion and boosted bass. The diaphragm is made of high-performance polymer materials with both toughness and compliance, and is repeatedly adjusted for the special cavity structure, so as to obtain such excellent linear distortion performance.

Closed Anterior Cavity Micro Dynamic Driver IEM

As entry-level in-ear earphones, Moondrop Quarks earphone is built into an unparalleled boutique in this tier. We achieved powerful sound quality at this price range after two years repeated adjustment. Quarks has very good frequency response characteristics, neutral tone, well done resolution, and easy to drive. Besides that, Quarks has far superior sound insulation capabilities than ordinary in-ear dynamic earphones because of the unique fully enclosed front cavity design, which allows you to enjoy music quietly in a noisy environment.

Patented Anti-Blocking Sound damping & Double Damping Structure

Front cavity of Quarks is equipped with a second generation patented anti-blocking sound damping, which improves durability and greatly reduces the possibility of blockage due to earwax.For the first time, we adopted a double damping structure, using two materials with completely different acoustic resistance characteristics to filter the mid and high frequencies, bringing a very smooth mid and high frequency response characteristics, greatly eliminating treble ringing. Making the earphone sound more natural and enjoyable.

Simple And Unique Appearance

The appearance and structural design are just like its name, revealing its meticulousness, compact size and can be worn in various ways.The fully transparent cavity allows a clear view of the driver and acoustic structure.

Replacement Moondrop Eartips

I bought the Quarks because the eartips it comes with are exactly the same as the stock ones included with the Moondrop Aria (and probably also the Starfield, LAN, Chu 2, and others). It's a relatively cheap way to harvest some spares.

The IEM itself is quite decent considering the price, though. It has a pleasant tuning that works well for most genres. Detail, clarity, imaging, and soundstage is limited, but still better than cheap earbuds you're likely to find at big box stores. If you're looking for a daily driver, you're better off spending a few dollars more for something like the Chu. But the Quarks made for a good "disposable" pair of IEMs that you don't have to worry about losing or damaging.

Great IEM

I was pleasantly surprise by the sound quality of these Quarks at a great price. I am a senior with very critical hearing and I believe that at the price a paid, it amazing.

Emmett Whyte

Great sound for the price has a good fit

DSP version is insanely good

These just blew my mind. For 15$ these are a steal. I first bought 2 sets, the usb-c dsp version and the standard one. Just moments after putting the dsp ones in my ears and playing some music I immediately hopped online to buy 5 more sets. They are so good that I just want to hand them out to my friends.

Smooth and detailed, with bass that rumbles and has impact. Just fantastic.
