Redefining the meaning of "full-range sound" in portable high-end audio, expertly covers the entire sonic spectrum with a single planar driver. The final note in our legendary tia™ line of UIEMs has been years in the making. Staying true to the tech-disruptive legacy of Fourté, Trio, and Duo, we looked to the past for innovative solutions to the modern challenge of tuning a single driver. In addition to a traditional electronic filter that subtly shifts the tonal balance, we have introduced the world's first Helmholtz resonator in an IEM.

The almost decade-long global success is being commemorated with a special edition.

Elevated through the use of an equally renowned element, titanium, for the shells, faceplates, and exclusive m20 apex modules. The strength, resilience, and bio-harmony of titanium, combined with the legendary sound, create the ultimate icon of timeless style and performance.

Planar Driver Technology

The 14.2mm planar driver's acoustic chamber integrates two Helmholtz resonators, meticulously tuned to acoustically sculpt its frequency response. This chamber is also engineered to include our apex core design, expertly relieving pneumatic pressure and enhancing the sense of physical space to a degree never before experienced in a single-driver IEM.

Combined with our patented LID technology, all of these innovations are housed in our most striking design update since the introduction of Fourté in 2016. These elements unite to deliver a sound that is quintessentially combining the exceptionally detailed transient response of planar technology with an unexpectedly robust low-frequency presence.

Sound Characteristics

Delivers immersive sound and impeccable spatial imaging. Its articulate highs extend beautifully with a warm and engaging low-end response - just like its custom counterpart. Offering reference-level detail, this has become one of the most highly regarded and sought after audiophile UIEMs.

Each ergonomic shell is machined out of a solid piece of titanium in a matte natural color finish.
