PRODUCT FEATURES

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 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 proprietary Nano-Membrane Dynamic Driver to create a high-performance hybrid in-ear monitor. 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. 

Legacy 4

The Legacy 4 was designed concurrently with the Legacy 5 to provide a unique twist to the lineup. With the beloved budget model, the Legacy 3, and the natural and smooth sound signature of the Legacy 5 in mind, we wanted the Legacy 4 to be a middle ground - both in terms of the tuning and price. Utilizing a completely new in-house 8mm poly-membrane dynamic driver for the low end, the Legacy 4 provides the impactful slam of the Legacy 3 and 5, but with a faster speed and enhanced texture. This new driver, matched with the tried and tested American Knowles ED29689 balanced armature (BA) and intuitive low-mid passive crossover design emphasizes a natural mid-frequency presentation. With a less aggressive crossover design than the Legacy 5, the mids of the Legacy 4 presents a more musical experience that ever so slightly adds a dash of warmth to the overall signature. With the partnership of Bellsing, we have developed a custom dual BA tweeter for the Legacy 4 that perfectly fits the mid BA driver. From the relaxed and smooth treble delivery of the Legacy 5, we have tuned the Legacy 4 to bring more upper treble presence, highlighting upper frequency overtones and details. This tuning and the extremely capable treble extension of our new tweeters brings an even greater level of airiness and shimmer to the mix, making the Legacy 4 an excellent IEM for both professional musicians and music enthusiasts alike. You can trust that the Legacy 4 will provide one of the most natural, accurate, and enjoyable musical experiences among any IEM’s of its class. 

Tuning Switch

The Legacy 4 crossover network is integrated into a 2-switch tuning system that allows the user to define the level of bass and mids. This tuning system means you can find the perfect sound signature no matter your musical preference!

A Completely Redesigned Look

Our team has worked hard to completely update our look! Paired with an OCC 4-core custom cable, you’ll find the Legacy 4 in an all new beautiful storage and travel case. 

Hand Crafted, Test for Quality Assurance

Each Legacy 4 unit is hand crafted, from the medical-grade German resin, to the internal circuitry, all the way to the painting of the faceplate. You can rest assured that your Legacy 4 is both a one of a kind in design and in line with all of our quality check protocols. Every pair is individually tested for left-right channel matching and inspected for defects prior to packaging and shipment. At Thieaudio, quality always comes first.

It's an upgrade, indeed (over the L3)

For my ears the overall sound signature of thieaudio Legacy 4 is balance with sub-bass boost, the bass has kick & rumble I need when listen to pop/rock music, yet it's never intrusive to the mid-range, the vocal still clear & a bit forward in some recordings, maybe a little bit lacks body for male vocal but it's fit my preference overall, the high region is brilliant too, the addition of 1 BA driver not only give a sparkly shimmer on high frequency but also give a better sense of space than the predecessor (thie L3), into technical aspect I think the most noticeable different of L4 over L3 is the soundstage, L4 have a better wide & tall soundstage that I've recognized when the first track playing, the resolution & detail retrieval is a bit better too, maybe it's not a huge upgrade from the L3 but what comes with L4 is a huge deal (the build & packaging), and for 200 bucks? it can never be a wrong choice.

Best Legacy IEM I have heard...period

What an excellent IEM. Seriously. I paired it with the Thieaudio EST cable and WOW!! is this IEM legit. I keep hearing people say it is a baby Clairvoyance and if it is, then what a great job for producing an IEM that gets close to the flagships for less than $200. Every time I pop them in and give them a listen with all sorts of music, the Legacy 4 handles everything with such sonic goodness, i am like....nice job Thieaudio...nice job. :)
