As entry-level in-ear earphones, Moondrop Quarks earphone is built into an unparalleled boutique in this tier. 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.

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.

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 material swith both toughness and compliance, and is repeatedly adjusted for the special cavity structure, so as to obtain such excellent linear distortion performance.

Two years of repeated adjustments, Quarks has achieved incredible excellent performance with a closed structure. It has a frequency response curve that is highly in line with HRTF (head related transfer function), bringing a natural and open sound field. Moderate bass gain makes Quarks more musical, bringing a fuller ambience sound.

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. Simple and unique appearance

Quarks, a pair of single dynamic driver IEMs,adopts a fully enclosed anterior cavity structure design for the first time . It can greatly isolate external noise, We could listen to the music at a lower volume and reduces the adverse effects of listening to music at high volume on hearing.
