Precision Acoustic Architecture for Every Scenario

The DUNU PRS6 is DUNU's first in-ear monitor with MEMS technology and an answer to the long-standing audiophile demand for flawless resolution and lightning-fast transients. It follows DUNU's Pro Response Sound (PRS) design philosophy, which is built around the way sound is used in real life. In competitive games, small audio cues reveal distance and direction. In music, timing, texture and detail carry the emotion of a performance. The PRS6 is tuned to respond quickly and to reproduce these details with clarity, whether for music, movies, gaming or everyday entertainment.

Six-Driver Hybrid Architecture

Each side of the PRS6 combines one custom 10 mm dynamic driver for the low frequencies, two custom balanced armature drivers for the midrange, two custom balanced armature drivers for the mid-high frequencies and one custom MEMS driver for the ultra-high frequencies. The dynamic driver supplies low-end energy for musical rhythm and immersive game ambience, while the balanced armatures resolve vocals, instruments and key details. The MEMS driver responds quickly to ultra-high-frequency information and helps to reproduce transient detail and spatial cues.

The setup is designed for a wide dynamic range with minimal distortion. Whether you are testing a new desktop DAC or simply getting lost in your favorite tracks, the PRS6 aims for precision and pure sound fidelity across the entire frequency spectrum.

Next-Generation MEMS Driver

The PRS6 is no regular hybrid in-ear monitor. Its ultra-high-frequency driver is a next-generation, chip-level passive MEMS driver based on silicon. It translates electrical signals directly into acoustic energy, without a traditional voice coil or magnet. As a solid-state, micro-machined diaphragm without the moving mass of a standard driver, it responds instantly to transient spikes and handles the uppermost frequencies with ease. This allows your high-res library to be reproduced with lightning-fast transients, fine harmonic overtones and airy treble decay, without compromises in the treble region.

Flawless Coherency with the Dual 4-Way Crossover

DUNU has years of experience in designing multi-driver hybrid IEMs and has used that expertise for the PRS6. A physical and an electronic crossover system work together to manage four frequency bands with high precision. Each driver stays within its intended range, interaction between the bands is reduced and transitions across the full frequency spectrum become smoother. The result is full coherency between the dynamic driver, the balanced armatures and the MEMS driver, and a presentation that brings out the intricate layers of even the most demanding recordings.

Pure Titanium Faceplates and Ergonomic Shell

The faceplates are made of pure titanium and finished with an ice-crystal pattern. The pattern is created through high-temperature vacuum sintering, slow cooling and acid pickling, and the color is added by anodization. Together with a precision-machined aluminum alloy midframe, this results in a distinctive technical look and a durable, carefully finished exterior.

The high-precision cavity is 3D-printed from resin and shaped around the anatomy of the ear. It supports a secure fit with reduced pressure during long listening sessions, provides proper isolation and keeps the internal structure, and with it the acoustic layout, consistent.

High-Purity Cable with Q-Lock Mini Plug System

The included cable uses four strands of high-purity, silver-plated single-crystal copper in a Litz structure for efficient signal transmission. The recessed 0.78 mm 2-pin connector is designed for a stable fit. With DUNU's patented Q-Lock Mini interchangeable plug system, both a 4.4 mm balanced plug and a 3.5 mm single-ended plug are included, so you can connect to your favorite DACs and DAPs right out of the box.

Gaming Microphone Compatibility

For professional esports use, the PRS6 works with the DUNU GAMING M1 boom microphone cable. The cable supports boom microphone, inline microphone and mute modes via a one-touch switch. It is available in 1.3 m or 2 m length with a 3.5 mm or USB Type-C connector.
