The DUNU TITAN S2 in-ear monitors (IEMs) represent a significant evolution in audio technology, designed to deliver an unparalleled listening experience. Building upon the solid foundation of its predecessor, the TITAN S, the TITAN S2 incorporates advanced engineering and high-quality materials to meet the needs of discerning audiophiles and professional users alike.

Acoustic Excellence: Core Features

At the heart of the TITAN S2 lies a sophisticated acoustic design featuring a Dual-Chamber Dual-Magnetic Circuit High-Performance Dynamic Driver. This driver setup integrates multiple precision acoustic elements: a high-rigidity dome with flexible suspension surround composite diaphragm, offering a natural frequency response and rapid transient response, resulting in precise and authentic sound reproduction. Utilizing dual magnetic circuits, both internally and externally, enhances the energy output and frequency response performance, ensuring stable and high-quality audio across various devices.

Frequency Response and Audio Performance

The TITAN S2 boasts a frequency response range of 5 Hz to 40 kHz, providing exceptional detail across the audio spectrum. With a sensitivity of 107 dB/mW (@1 kHz) and an impedance of 16Ω, these IEMs are both easy to drive and capable of delivering powerful, clear sound. The low total harmonic distortion (THD) of <0.3% at 1 kHz further ensures audio fidelity.

Build Quality and Design

Constructed from high-density alloy material and finished with chrome plating, the TITAN S2’s housing is both durable and aesthetically pleasing. The chrome-plated finish not only adds to the IEM’s durability but also ensures it remains resistant to scratches, maintaining its pristine appearance over time.

Innovative Cable System

The TITAN S2 features DUNU’s proprietary Q-Lock Mini Series Interchangeable Plug System (same as Kima 2 IEMs), which provides versatility and convenience. The system includes both 3.5mm single-ended and 4.4mm balanced plugs, allowing users to switch between different audio sources without needing separate cables. Additionally, the premium 4-core OCC copper and silver-plated OCC mixed cable is encased in a nylon shock-absorption mesh for durability and signal purity, ensuring that the audio quality remains uncompromised. The detachable cable design with standard 0.78 2-pin connectors offers broad compatibility and enhanced durability.

Comfort and Accessories

Comfort is a key consideration in the design of the TITAN S2, with a range of eartips included to ensure a perfect fit for every user. The S&S eartips, crafted entirely from flexible silicone, enhance soundstage performance and provide studio-grade sound reproduction. Candy eartips, featuring thickened ducts for enhanced support, improve atmospheric presence and vocal density. Balanced eartips offer a balanced and straightforward sound profile, suitable for various music genres. The atmosphere enhancement eartips, with red-colored ducts, boost bass performance and enhance the atmospheric presence, especially for pop music. Additionally, the package includes a storage pouch and a cable clip for convenient storage and cable management.

Selling points

• Exceptional Audio Quality: The dual-magnetic circuit and dual-chamber driver system ensure a smooth, natural, and high-fidelity audio experience.
• Durable Build: Chrome-plated all-metal housing provides durability and scratch resistance.
• Versatile Cable System: The Q-Lock Mini interchangeable plug system allows easy switching between balanced and single-ended outputs.
• Comprehensive Accessories: A wide range of eartips and other accessories ensures optimal comfort and usability.

Potential deal breakers

• Price: The advanced technology and premium materials may place the TITAN S2 at a higher price point.
• Weight: At 17.2g per side, some users might find the IEMs slightly heavy for prolonged use.
• Learning Curve: The interchangeable plug system might require a bit of practice for seamless use.

The DUNU TITAN S2 stands out with its combination of cutting-edge acoustic technology, superior build quality, and thoughtful design, making it an excellent choice for audiophiles seeking top-tier in-ear monitors. The technical specifications of the TITAN S2 include a weight of 17.2g per side, a frequency response range of 5 Hz to 40 kHz, an impedance of 16Ω at 1 kHz, a sensitivity of 107 dB/mW (@1 kHz) and 125 dB/Vrms (@1 kHz), and a total harmonic distortion (THD) of <0.3% at 1 kHz. 

The cavity is made of high-density chrome-plated alloy, and the cable is a 4-strand OCC copper and silver-plated OCC copper litz wire, with a length of 1.2m ± 0.1m. The connectors are 2 pin 0.78mm, and the plug system includes both 3.5mm single-ended and 4.4mm balanced options. You can buy the Dunu Titan S2 from Dunu Topsound website.
