64 Audio Volur 10 Driver Hybrid In Ear Monitor

The pulsating heart of Volür is made up of two new custom 9mm dynamic drivers in a True Isobaric configuration, delivering unprecedented sonic capabilities in the low-frequency (LF) band. While 64 Audio's direct radiating tia high-driver remains the criterion in high-frequency (HF) performance, 64 Audio's new tia waveguide optimizes its efficiency while offering greater tuning control. The six low-mid and single high-mid balanced armature drivers carry through to Volür. Their implementation was wholly re-engineered to maximize internal space while integrating 3D printed acoustic tuning features.

What is soon to be a new benchmark in acoustic delivery, Volür is capable of visceral bass while leaving room for the rest of the spectrum to shine. The saturated mids continue to evoke a similar analog warmth found in Nio, while the highs propel it into the territory of some of the most resolving audio products in the world.

The goal with the LF response was to increase quality, not just quantity, and the dual isobaric drivers deliver both beautifully. Due to its distinctive damping qualities, you hear more of the music and less smear, in a sense lowering the noise floor to a darker background between notes/beats and allowing details to shine. There’s a more palpable impact, with subtle sub-bass information revealing the artist’s true intentions. This head-filling bass also allows you to experience a full sound at extremely low volumes, especially with a more isolating module like m20.

The familiar Nio mids, known for their rich character, maintain that signature quality, delivering an almost tube-saturated presentation. Volür’s unique response curve enhances that experience with holographic center imaging that really shines with vocals, making them feel as if they are floating inside your head.

The tia waveguide plays the biggest role in improving HF response since 64 Audio's invention of the direct-radiating driver. The clarity presented by the HF band, and Volür’s unbelievably wide sound-stage, puts it in the same sonic resolution category as the flagship Fourté. This is a rare high-end audio product that bridges the gap between indulgent bass-loving and technical detail-oriented audiophiles.

64 Audio's cone-to-magnet isobaric driver configuration consists of two drivers connected by an acoustically inert coupling chamber. One diaphragm is fully sealed off, while only the other contributes sound pressure. This complex application results in better damping, lower distortion, twice the power handling (because there are two coils and two motor structures), and extended LF response.

Because this iso-group needed to be wired in series, we worked with 64 Audio suppliers to create a new 9mm dynamic driver with an upgraded n54 magnet and 25μm PU/115°C + 19μm Ti Cone to increase sensitivity. To further shape the sound, we used a high-precision textile mesh acoustic low-pass filter (originally developed for Fourté Blanc).
