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.
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!
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.
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.
