Ushering in a new era of technological innovation, Volür is a 10-driver hybrid UIEM, building on the heritage of Nio. The pulsating heart of Volür is made up of two new custom 9mm dynamic drivers in a True Isobaric configuration, delivering unprecedented low-frequency capability. While our tia™ high-driver remains the criterion in high-frequency performance, our new tia waveguide optimises 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 re-engineered to maximise space while integrating 3D printed acoustic tuning features.



The isobaric low-drivers’ damping decreases low-frequency smear, lowering the noise floor to a darker background between notes and beats, allowing details to shine. This creates more palpable impact, with subtle sub-bass information revealing the artist’s true intentions, and a full sound at low volumes. Mids maintain that signature rich quality; an almost tube-saturated presentation. Upper-mids enhance holographic center imaging that really shines with vocals. Our tia waveguide plays the biggest role in improving HF response since our invention of the direct-radiating driver; increasing clarity and stereo imaging.


The outer shell remains the same size, while all significant structural changes occur internally. The faceplate now features a sleeker chamfer, seamlessly blending with the matte black-finished aluminium shell. The final cosmetic touch comes in the form of an homage to Nio: a dreamy purple abalone chip made from responsibly harvested New Zealand Paua shell. 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 analogue warmth found in Nio, while the highs propel it into the territory of some of the most resolving audio products in the world.


Featured Technology


True Isobaric

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.

With the iso-group 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).


Tia® waveguide

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.


Patented Technology



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.



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. While it looks similar to many of our UIEMs, the internal construction of the Apex system is redesigned to maximise space for the LF bore incorporated into the mid-driver housing.



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.
