Volür
Ushering in a new era of technological innovation, Volür is a 10-driver hybrid universal in ear monitor (UIEM), building on the heritage of our first high-driver count hybrid, Nio (released in 2020). The successful recipe of this hybrid platform propelled our appetite for discovery, resulting in one of the most challenging and rewarding developments in our history of pioneering industry-shaping high-end audio. Joining the ranks of our other technological powerhouses, like U18s and Fourté, this small package is filled with an almost impossible amount of proven and novel acoustic science. 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 our direct radiating tiaTM high-driver remains the criterion in high-frequency (HF) performance, our 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.
Tia®
The direct-radiating tia high-driver is fitted with our new tia waveguide to increase the efficiency and general amplitude of the HF band. In order to refine this HF response, special diffusion windows were integrated to the front and side of the waveguide. The tia waveguide also serves as a mounting mechanism, mating to the mid-driver housing, offering exact driver positioning during manufacturing. Tubeless In-Ear Audio is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system consists of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. Volür features two major elements of the tia system: the tia driver and the tia single-bore design. LID® Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 10 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
Apex®
While it looks similar to many of our UIEMs, the internal construction of the Apex
system is redesigned to maximize space for the LF bore incorporated into the
mid-driver housing. Air Pressure Exchange is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation, enabling musicians and
music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in four module variations for Volür: mX, m12, m15 and m20.
True IsobaricTM Configuration
Our 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 our 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).
