Legacy 4

Designed alongside the Legacy 5, the Legacy 4 offers a unique twist to the lineup. Considering the much-loved budget model Legacy 3 and the naturally smooth sound signature of the Legacy 5, we wanted the Legacy 4 to sit between these two models in both tuning and price. The Legacy 4 uses a brand new internal 8mm multilayered dynamic driver for the low end, offering the punchiness of the Legacy 3 and 5 but with faster speed and enhanced texture. This new driver is paired with the proven American Knowles ED29689 balanced armature (BA) and an intuitive mid-low passive crossover design, emphasizing natural midrange presentation. Compared to the Legacy 5, the Legacy 4 features a less aggressive crossover design, resulting in a more musical midrange experience with a slight warmth added to the overall signature. In collaboration with Bellsing, we developed a custom dual BA tweeter for the Legacy 4 that perfectly complements the mid-BA driver. While maintaining the smooth treble delivery of the Legacy 5, we adjusted the Legacy 4 to bring more treble presence, highlighting high-frequency overtones and details. This tuning and the super-high treble extension of our new tweeter bring a higher level of clarity and shimmer to the mix, making the Legacy 4 an excellent IEM for professional musicians and music enthusiasts. You can trust that the Legacy 4 will deliver one of the most natural, accurate, and enjoyable musical experiences among any similar IEM.

Tuning Switches

The Legacy 4’s crossover network is integrated with a 2-switch tuning system, allowing users to define the levels of bass and mids. This tuning system means you can find the perfect sound signature regardless of your music preference!

Our team has been working hard to completely update our appearance! Paired with an OCC 4-core custom cable, you will find the Legacy 4 housed in a brand-new elegant storage and travel case.
