Pinnacle of THIEAUDIO’s Achievements

The R&D behind the THIEAUDIO Valhalla took over two years, with input from engineers from multiple countries contributing to its development. The Valhalla was designed with three core goals: (1) Push the limits of driver capacity in an IEM format; (2) Achieve the highest degree of technical performance; (3) Establish THIEAUDIO’s tonal superiority. With five years of continuous technological and artistic development, the Valhalla reflects THIEAUDIO's pursuit of excellence in the global IEM market.

Pushing the Limits: 19 Drivers Per Side

With 19 drivers per side, the Valhalla achieves exceptional resolution while maintaining a comfortable in-ear design. By utilizing a greater number of drivers, it reduces the workload on each unit, resulting in unparalleled clarity and technical performance. This engineering feat allows the Valhalla to stand as THIEAUDIO’s most detailed and refined product to date.

Genuine Imported Drivers

The Valhalla is equipped with carefully selected components sourced from industry leaders Knowles and Sonion. Each earbud features four Sonion 38D1XJ007 sub-woofers, ten Sonion E50DT0005 low-midrange drivers, four Knowles RDE 33729 mid-treble drivers, and one Knowles WBFK 30095 ultra-treble tweeter. These imported drivers ensure precise, high-fidelity audio reproduction, meeting the standards of professional and enthusiast users alike. 

PBS: Precision Bass System

PBS (Precision Bass System) is THIEAUDIO’s innovative solution for delivering a true subwoofer-like experience in an IEM. Developed over the course of a year, PBS integrates multiple low-frequency drivers within a specially designed resonance chamber. This chamber is optimized to achieve a 200Hz bass shelf with enhanced depth and clarity, while the addition of a diversion tube and pressure relief vent precisely targets ultra-low frequencies from 5Hz to 20Hz. The design not only enhances sub-bass extension and impact but also reduces ear fatigue by relieving built-up pressure in the ear canal. By combining acoustic precision with ergonomic design, PBS delivers an immersive and comfortable listening experience.

A Feat of Acoustic Engineering

As THIEAUDIO’s flagship IEM, the Valhalla incorporates advanced crossover and tubing technologies. Its 4-way passive crossover network, combined with a 4-bore acoustic tubing system, ensures precise frequency division and smooth transitions across the entire spectrum. Unlike typical 1st-order crossovers, the Valhalla utilizes multiple 2nd-order networks for pinpoint accuracy. Additionally, impedance neutralization strategies ensure consistent performance regardless of the audio source. This sophisticated engineering results in an unmatched level of clarity and balance.

Tonal Superiority

The Valhalla embodies THIEAUDIO’s renowned signature tuning. The bass is characterized by a subwoofer-like impact, featuring a 10dB bass shelf that quickly decays and cuts off at 200Hz, avoiding any bleed into the mids. The midrange is tuned with a gentle 1dB slope from 200Hz to 800Hz, balancing neutrality with a touch of warmth. The treble features a smooth 8dB pinna gain at 2.8kHz, with extended ultra-treble output reaching up to 40kHz, offering brilliance and clarity without harshness. This tonal balance makes the Valhalla suitable for both professional and casual listening.

A Promise to Quality

The Valhalla reflects THIEAUDIO’s commitment to craftsmanship and quality. Each unit is handcrafted by a single engineer, requiring an entire day to complete. Drivers are meticulously measured and hand-paired before assembly, and each completed unit undergoes three stages of inspection: post-assembly testing, cosmetic checks, and accessory verification.

EliteNoir Cable V2 (Updated)

The Valhalla is paired with the updated THIEAUDIO EliteNoir Cable V2, featuring silver-plated copper conductors with aluminum hardware, wrapped in durable black PVC. Utilizing spiral shielding and Litz Type II wiring, the cable minimizes signal loss while enhancing long-term durability. Designed to preserve a neutral, uncolored sound signature, the EliteNoir Cable V2 enhances soundstage openness, refines detail retrieval, and delivers clean, controlled performance—allowing the Valhalla to perform at its full potential.
