64 Audio Volur, In-Ear Monitors: 10 Driver Hybrid Universal Earphones IEM (Volur)

64 Audio's newest UIEM, Volür is a 10-driver hybrid design. This 4-way system is broken out into 2 x 9mm DD (low), 6 BA (mid), 1 BA (hi-mid), 1 tia™ BA (high).

This release, originally inspired by Nio, is the culmination of research and development spanning many years. At the heart of Volür are the two new custom 9mm dynamic drivers in a True Isobaric configuration. This cone-to-magnet design is responsible for improving damping, lowering distortion, increasing power-handling, and extending the LF response. Bottom line, we were looking for quality over quantity and we ended up improving both.

Another goal with improving our high-driver count hybrid platform was elevating high-frequency response. Our new tia waveguide increases amplitude while remaining, not only listenable, but extremely resolving. The detail retrieval and soundstage provided by this component elevates the sound of Volür to the summit of high-end audio products.

While it maintains the signature rich character of Nio's mids, to maintain the ergonomic outer shell dimensions almost all of the internals had to be reimagined. From the internal wall thickness of the shell, 3d printed driver manifolds, LF bore, to the mounting mechanism connecting the mid-driver housing to the highs; this technological powerhouse is nothing short of an engineering marvel, if only for the amount of components and technology that it contains within it. Most visibly of all the changes is the sharper faceplate, which replaces our traditional rounded edges with a chamfered edge.
