Introducing ThieAudio
Thieaudio was launched in 2019 as a creative endeavor of Linsoul Audio. The goal of Thieaudio was to serve as a creative platform for gathering the best teams of engineers to inspire revolutionary audio products for audiophiles and professionals alike. For each project, we hand select the most innovative and renown engineers in his or her field to oversee the design, engineering, and manufacturing of the products. The first chapter, the Thieaudio Phantom, drew overwhelming praise from the international community and was even applauded as the new standard for planar magnetic headphones by some.
Gathering this momentum, we are proud to present the next chapter of Thieaudio - the Voyager and Legacy series. These new series of In Ear Monitors were created to bring about unparalleled sound performance that would rival the leading international brands.
The Voyager series was designed as the launch of Thieaudio’s pursuit in the realm of in-ear monitors, and features some of the most innovative techniques we have to offer. The Leagcy series takes the most trusted and established knowledge and designs available in the industry, and presents them in a refreshing and refined manner. We believe the Voyager series may be more suited for musicians, while the Legacy series may better fit audiophiles and music enthusiasts.
Focusing on three primary values - musical tuning, high-fidelity sound quality, life-like listening experience - Thieaudio’s new project aims to redefine the true potential of in-ear monitors for both enthusiasts and professional musicians. So we welcome you to step in, and open your ears to a world of audio like nothing before.
8+1 = Power
The Thieaudio Legacy 9 combines the technical prowess of balanced armatures with the full power of a 10mm Dynamic Driver. Utilizing eight genuine American Knowles and Danish Sonion balanced armatures, the treble range is effectively enhanced, bringing out all of the natural details and clarity of the music, as well as an elegant airy atmosphere that accurately reflects the studio and stage. The large dynamic driver brings about a full and impactful bassline that is sure to rumble the ears. We believe the Legacy 9 sets the bar for one of the best low-frequency performances out of all in ear monitors. However, our tuning style also reflects the need for a clean and balanced musical experience, thus emphasizing the vocal range to highlight texture and shimmer of both male and female voices. Our integrative 4-way crossover system coherently distributes all drivers to their respective frequency ranges, preventing overlap and phase inconsistencies. Highest quality drivers, masterful tuning, and skilled engineering sets the Legacy 9 as the highest competition for hybrid in ear monitors today. As the flagship model of the Legacy series, the Legacy 9 puts out a powerful, balanced, and captivating sound. We believe the Legacy 9 is among the best tuned in-ear monitors available today.
Exotic Solid Wood Housing and Faceplate
While power, warmth, and clarity define the musical quality of the Legacy 9, its appearance and build can be described as intricate and elegant. Every component is hand built, piece by piece using only the highest grade genuine solid wood. There are only a couple of manufacturers around the world offering full wooden shell and faceplate options, and these often cost (literally) thousands of dollars. At Thieaudio, we wanted not only the sound to be boutique, but the presentation and appearance of the Legendary series to be bespoke. Each monitor is hand carved out of select exotic solid wood, and this process alone takes an entire day to complete. Our skilled staff each have over a decade of experience building custom in ear monitors, and each unit is crafted unto perfection. Each earpiece is unique, and there is nothing on Earth that will look like it. You can rest assured knowing that your in ear monitor is safe to use, durable, and a masterwork of art.
Custom Ultra-pure 7N OCC Copper Cable
To maximize the sound quality of the Legacy 9, we have undergone extra expenses to hand-braid an 8-core ultra-pure 7N oxygen-free copper cable. This custom cable minimizes electrical resistance, allowing the sound to be fuller, more clear, and extend the soundstage. We also love how the copper contributes to the bass and midline, strengthening the full sound of the Legacy 9.
