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 renowned engineers in his or her field to oversee the design, engineering, and manufacturing of the products. Gathering the momentum from the success of the Thieaudio Phantom planar magnetic headphones, as well as the Voyager, Legacy, and Signature series In-Ear Monitors (IEM’s), we are committed to the continual expansion on the limits of high-fidelity audio. We welcome you to join us and experience excellence in musical performance. 

Legacy Series

The Legacy series capitalizes on Thieaudio’s engineering capabilities to merge the latest driver innovations, creating a lineup of the ultimate high-performance hybrid in-ear monitors. Geared towards the discerning audiophile and music enthusiast, the Legacy series re-envisions the qualities that make up high-fidelity audio to present a unique combination of enjoyable tuning that also excels in technical performance. With each model of our Legacy Series, we hope to reveal a refreshing new perspective on your daily listening experience, immersing you deeper into the music.

When Legendary Drivers Meet

When most IEM manufacturers develop dual driver IEM’s, they are purposefully fated to be the entry-level, low-tier, and affordable compromise to their more expensive counterparts. For this reason, cheaper, less efficient drivers are selected, put together with less thought on acoustic design, ultimately resulting in an under-performing monitor. Thus, when our team came together to craft the Legacy 2, we dedicated ourselves to achieve the highest performance possible, carefully selecting components, and merging them through months of sonic engineering. 

Bass performance has always been of particular importance to the Thieaudio team, which is the reason why the Legacy series, with its incorporation of dynamic driver woofers, was started. Our team has come a considerable way in developing dynamic drivers, and we are proud to utilize our latest advancements into the Legacy 2. Featuring our new proprietary closed-back 10mm Beryllium dynamic driver, the Legacy 2 takes the biggest leap yet in bass performance. Beryllium drivers have developed a cult-like following in the audiophile community due to the stiffness of this element, which results in extremely quick responses. By using stronger internal magnets and a new acoustic casing design, we have taken this driver to its full potential, producing low-frequency responses beyond anything the Legacy series has achieved so far. 

In selecting the mid-high frequency driver, we have decided to utilize the tried and true legendary balanced armature, the Knowles ED29689. Famed particularly for its performance in popular single-BA driver monitors, the Knowles ED29689 has been widely acclaimed as the foundation of all balanced armature drivers, and still stands today as the most capable and best performing driver. Particular to our interests, the ED29689 features a completely neutral mid-frequency response, accurate mid-treble transition, and a highly resolving treble playback. 

By using similar tuning strategies as those found in our Signature series models, the Legacy 2 has been engineered to produce a powerful sub-bass impact that transitions crisply to the mid-frequencies, which in turn are presented naturally, with minimal coloring. The treble has been tuned to perfectly balance the ED29689’s high calibre treble resolution and the human ears’ preference for high-frequency decay. Through careful selection of the drivers and intricate tuning strategies, we have created the ultimate 2 driver in-ear monitor, that beyond its mere name, is truly a performance-grade monitor for both stage and audiophile use. In no way is the Legacy 2 a compromise, and we are confident that it stands to compete against any competition in the field, regardless of the driver count.

Good but not the best, specially for the price

I've used the Legacy 2 for about one month straight now but, when I recently got the Tin HiFi T2+ and the KZ X CRN Zex pro, I wondered why this IEM cost so much.

The bass is punchy, highs aren't peaky (even at high volumes), good imaging for gaming (Rainbow 6 Siege), decent sound stage, good mids, and an overall safe-sounding IEM. It also has great packaging, a good case, great cable, usable stock ear tips, a seemingly universal fit, along a great overall package.

Highs lack the "air" and imaging capabilities that the T2+ have, lacks bass extension, is not as great as ZEX Pro in critical listening, and is perfect at being average with no specific traits that scream 100$.

I bought this IEM as a replacement for my ATH MR7, and in that regard, I find the L2 better than the MSR7 in almost everything except the sound stage. I like the looks of the IEM and its performance in-game but, I can't justify the price for casual/critical listening and using it for games that require good positional audio.

Buy this IEM if you want to blow 100$ on something that you could use to listen to anything without expecting great detail, a breathtaking sound stage, or any stand-out features. It's not something I'd recommend when better alternatives at a lower price are present.

Best IEM around $100

I have bought many IEMs in this price range— from Moondrop to Meze— The Thieaudio Legacy 2 is the very best IEM anywhere near this— and I rank it higher than the Legacy 4, because of the new dynamic driver. I think it’s the best value under the $400 dollar mark. These have slam, great imaging, comfort, and a great cable. This is the one to buy. YouTube video placeholder

Full of Subbass & great separation for under $90

Got this from winning giveaway from directors garage of Michael De Lazzer youtube channel.

And yes i love love love the sub bass that are not lacking for my taste, mids are presented good for all around and presented laid back & treble is decent far from sibilant, the amazing point of these legacy 2 is it separation, for under $100 they surprised me. wideness is good and still inside my head feels, unlike the $1k that can make 3D surrounding outside my head feels. i used to use & still use some iems around under $300 like sony XB75AP, sony XBA-2, bose soundtrue ultra & jvc ha-fx850 and well i can't say they are average in terms of sound quality but compared to legacy2 for me (whom love subbass) has surpassed them for all around genre, but for my taste this iem is shine more with any sub bass / electronics genre.

The design is quite small remembering just using 2 drivers, and they have wings design that kinda grip in ears, faceplate design is beautiful, the blue remaind me the ocean & create calm feelings.

From the cable i love them, no microphonics, tangle hassle free, feels nice just love the cable, i even choose this cable with ease from audio 46 iems that came from their box.

No wonder this legacy2 won the shoot-out agains the two moondrops aria & starfields for mr. michael taste.

Thank You for linsoul who has sponsored directors garage channel, me & my hubby never miss an episode of them.

Solid pair of in ears.

I ordered these and blon -08 at the same time-ish . They sound good out of the box. I like the sound. It’s more of a forward and fast sound; to my ears. I also have the legacy 3, which is my go to pair to grab. The legacy 2 are great, but for a little more money you could get the legacy 3, which from personal listings, I find to be more open and fun to listen too. Also the legacy 3 seem easier to drive and are loud and clear no matter what they are connected too phone/ portable Dac/Amp combo. Overall if you want a good pair of in ear headphones the legacy 2 and 3 are amazing , light weight, and pleasing sound.

Good but not sure about price?

Purchased a few months after KZDQ6 ( both recommended by BGGR ).

Excellent bass and slam.

Initially I was slightly disappointed as these were over 3 times the price.

Vocals slightly recessed and sound stage not as open compared with the KZDQ6.

However imaging is a little better.

Not as “airy”, darker but less fatiguing for longer listening sessions.

Beautiful build, feel and finish ( better than KZ whose face-plate came off after a month ).

Very light and very comfortable ( stock silicone tips and cable).

Ultimately better than KZDQ6 but can't quite decide if they are worth the price.

Compétent but too basic

The Legacy 2 has good bass, recessed middle and thin treble. A dark very basic monitor.

Best Thieaudio IEM

Michael De Lazzer
Best IEM Under $350 Dollars

These IEMs are quite simply the best budget in-ear on the market today. The beryllium dynamic driver digs deep into the sub-bass while providing tremendous speed and detail. There are headphones at the $1000 dollar level that produce worse bass than the Legacy 2. These are the real deal.

More drivers does not necessarily mean a better headphone. Fewer drivers allow for better imaging, alignment, and fewer timing issues. Thieaudio has capitalized on this advantage and minimized the downside by using quality materials and drivers.

The Legacy 2 isn't a perfect headphone, if one exists at all. The treble can run a bit harsh here and there, depending on the source and song. But you will be hard-pressed to find anything better at or around this price point. This is a solid audiophile experience. Thieaudio and Linsoul have given us the best Legacy yet.

El rocío de verano - Thieaudio Legacy 2

Desde el Legacy 3 hasta Legacy 5, Thieaudio ha demostrado su fortaleza con una excelente calidad analítica y afinación. Esta vez, ¿el lanzamiento de Legacy 2 puede volver a sorprendernos en el terreno del precio económico? Vamos a averiguar.

Legacy 2 usa una configuración 1DD + 1Ba. Desde el punto de vista de la apariencia, la cavidad del legacy 2 es mucho más pequeña que los productos de unidades múltiples, y el peso es más liviano que las generaciones anteriores. Se adopta el esquema del color azul mediterráneo y se utilizan paneles dibujados a mano. Cada pieza es única. Los elementos de diseño generales dan una sensación más joven y fresca.
Los auriculares están distribuidos aleatoriamente con 4 hebras de cable plateado OCC, las piezas del hardware son excelentes en mano de obra, el cuerpo del cable es suave y no es fácil de anudar. Es un cable con un excelente material y rendimiento de sonido en este rango de precios. Para los usuarios promedio, no hay necesidad de actualizar.

En términos de rendimiento de sonido, En primer lugar, el uso de Knowles BA Driver y un Beryllium Dynamic Driver como legacy 2 no requiere un gran empuje y es más fácil introducir una presión de sonido satisfactoria. Incluso si se usa un teléfono móvil, puede proporcionar un sonido relativamente bueno. Por supuesto, al cambiar la interfaz a un reproductor de música profesional, la mejora es relativamente obvia.

Como producto de nueva generación de Thieaudio, aunque el posicionamiento es de nivel de entrada, también podemos sentir la afinación cada vez más madura de Thieaudio. Legacy ha realizado un ajuste relativamente equilibrado de afinación y calidad. Mientras mantiene el análisis general de alta calidad, Legacy 2 puede crear un sonido musical extremadamente cálido y relajante. Especialmente para algunas de las grabaciones musicales modernas, legacy ha funcionado bastante bien.

En términos de baja frecuencia, legacy 2 tiene la cantidad adecuada de volumen y es muy rápido. La parte de baja frecuencia del análisis también es más clara y puede brindar una atmósfera muy esponjosa, cómoda y suave. Hablano alta frecuencia, la sensación general de legacy2 es ligeramente moderada, suave y de baja saturación. Al tiempo que garantiza la calidad analítica requerida, tiene una perfecta sensación de frizz.

En términos de frecuencia media, la afinación del legacy 2 es relativamente neutra y no reduce deliberadamente el grosor del rango medio para crear un campo de sonido amplio. Aunque todavía hay una cierta brecha con la afinación de voz de Legacy 5, Legacy 2 puede satisfacer a algunas personas la necesidad de brillo de sonido, pero no enfatiza demasiado el rendimiento de la textura de la voz humana, no tendrá ningún sentimiento estimulante, la posición de la voz humana es moderada y puede ser competente para la demostración de muchos tipos de música.

El campo de sonido no es demasiado grande y toda la forma está cerca de un campo de sonido circular, que se considera excelente entre los productos al mismo precio. Las grabaciones modernas como la música pop y la música electrónica tendrán mejores resultados. Durante la prueba, descubrí que al usar Cayin N3Pro con legacy2, se puede tener un rendimiento de sonido muy cómodo y sin cansarse después de escucharlo durante mucho tiempo.

Como nuevo producto básico de Thieaudio, legacy2 es liviano, compacto, cómodo de usar y tiene una apariencia refrescante. No requiere altos requisitos de interfaz. Es una tendencia de tuning popular. No te cansaras de escucharlo durante mucho tiempo. El precio es razonable. Los amigos que quieran probar estos productos de audio pueden empezar con este legacy 2.
