Pinnacle of THIEAUDIO’s Acoustic Mastery: The THIEAUDIO Valhalla represents over two years of research and development, drawing on the expertise of engineers from multiple countries. Designed with three key goals in mind—pushing driver capacity limits in IEMs, achieving unparalleled technical performance, and showcasing tonal superiority—the Valhalla stands as the culmination of THIEAUDIO's technological and artistic breakthroughs over the past five years.

Cutting-Edge 19-Driver Design: The Valhalla features an impressive array of 19 drivers per side, demonstrating the highest resolution among THIEAUDIO products. This includes four Sonion 38D1XJ007 subwoofers, ten Sonion E50DT0005 low-midrange drivers, four Knowles RDE 33729 mid-treble drivers, and one Knowles WBFK 30095 ultra-treble tweeter. This intricate combination of premium drivers ensures exceptional technical precision and remarkable sound quality.

Precision Bass System (PBS): THIEAUDIO's proprietary PBS is engineered to emulate a true subwoofer experience in an IEM. This innovative system features a meticulously designed resonance chamber and low-frequency filter cavity, achieving a precise 200Hz bass shelf and extending bass impact down to ultra-low frequencies of 5Hz to 20Hz. The PBS not only enhances bass depth and clarity but also minimizes ear fatigue through a pressure relief valve, ensuring both acoustic excellence and user comfort.

Tonal Precision and Superior Tuning: The Valhalla employs advanced 4-way passive crossovers and a multi-tubing acoustic network to achieve THIEAUDIO’s signature tuning. Its balanced sound profile includes a 10dB bass shelf with quick decay and a sharp cutoff at 200Hz, delivering powerful bass impact without muddying the low-mids. The midrange features a gentle 1dB decay slope from 200Hz to 800Hz, providing a perfect blend of neutrality and warmth. The treble is precisely tuned with an 8dB pinna curvature at 2.8kHz, aligning with human auditory perception and extending ultra-treble performance up to 40kHz.
