Moondrop Quark 2 DSP Type-C Earphone with Microphone

MOONDROP Quark 2 DSP USB-C IEM with Microphone Overview

The MOONDROP Quark 2 is a compact USB-C DSP in-ear monitor with microphone designed for everyday music, gaming, calls, and portable HiFi listening. As the next generation of the original Quarks series, it combines a specially optimized micro dynamic driver, LCP dome composite diaphragm, digital DSP processing, and convenient USB-C connectivity in an affordable wired IEM.

Built around a closed front-cavity acoustic design, the Quark2 uses an efficient N52 magnetic circuit and lightweight CCAW voice coil to improve driver response and energy conversion. It also supports 32-bit/384kHz hardware decoding and graphical online DSP tuning, giving users more flexibility than a conventional entry-level wired earphone.

LCP Composite Micro Dynamic Driver

The MOONDROP Quark2 uses a micro dynamic driver featuring an LCP dome composite flexible suspension diaphragm. Its driver structure is specifically optimized for the Quark2’s closed front acoustic cavity to provide controlled bass, clear midrange reproduction, and detailed high frequencies from a very compact enclosure.

An efficient N52 magnetic circuit works together with a lightweight CCAW drive coil to improve energy conversion efficiency and transient response. This helps the small dynamic driver respond accurately to changes in the audio signal while keeping the overall earphone compact and lightweight.

Closed Front-Cavity Acoustic Design

The Quark2 features a closed front-cavity structure developed to improve both acoustic performance and passive sound isolation. MOONDROP refined the internal acoustic structure using simulation-based design methods to better control the driver’s behaviour inside the small housing.

The closed design also helps reduce outside noise naturally, making the Quark2 suitable for commuting, studying, office use, gaming, and everyday listening without relying on electronic active noise cancellation.

32-Bit/384kHz Hardware Decoding

Unlike a conventional analog 3.5mm earphone, the MOONDROP Quark 2 USB-C integrates digital audio processing and supports hardware decoding up to 32-bit/384kHz.

This allows compatible phones, tablets and computers to send digital audio directly to the earphones through USB-C, making the Quark2 a convenient option for modern devices that no longer include a dedicated 3.5mm headphone jack.

Interactive DSP Tuning

The Quark2 supports graphical online interactive DSP, allowing users to customize its sound response through MOONDROP’s supported tuning platform. DSP processing provides additional control over the earphone’s frequency response without requiring a separate external DAC or hardware equalizer.

This feature makes the Quark2 particularly interesting for listeners who want an affordable IEM while still having the option to experiment with different tuning preferences.

Refined VDSF-Based Sound Tuning

MOONDROP applies its acoustic tuning experience to the Quark2 with a response designed around the company’s VDSF target philosophy. The goal is a balanced presentation with controlled bass, natural vocals, clear instruments and smooth high-frequency reproduction.

Its full-link nonlinear distortion is rated at THD ≤0.05% at 1kHz, helping maintain clean reproduction during normal listening.

Dual Acoustic Filter Design

The Quark2 uses a dual acoustic filter structure with different damping materials to control unwanted high-frequency resonances. This approach is designed to smooth the upper-frequency response while retaining useful detail.

For an entry-level IEM, this additional acoustic control helps provide a more refined listening experience without relying entirely on electronic processing.

USB-C UAC 2.0 Connectivity

The MOONDROP Quark2 uses a USB-C interface based on the standard UAC 2.0 audio protocol. It can work with a wide range of compatible USB-C devices including Windows PCs, Macs, Android smartphones and tablets, as well as supported USB-C iPhones and iPads.

Compatibility can still depend on the USB audio implementation of the source device, so users should confirm USB audio support when pairing it with less common devices.

Three-Button Control and Built-In Microphone

An integrated three-button in-line control provides convenient access to supported volume, playback and call functions without reaching for the connected device.

The built-in microphone also makes the Quark2 practical for voice calls, online classes, meetings, gaming communication and other everyday situations where both audio playback and voice input are needed.

Wired Audio for Gaming and Video

Because audio is transmitted through a wired USB-C connection, the Quark2 avoids the additional wireless transmission delay associated with Bluetooth earphones. This makes it a practical option for gaming, video playback and other applications where audio synchronization matters.
