64 Audio Volür Universal Hybrid In-Ear Monitors
The 64 Audio Volür is a revolutionary 10-driver hybrid IEM that introduces next-generation isobaric bass technology alongside flagship-grade tia™, apex™, and LID™ systems. Featuring two custom 9mm dynamic drivers in a True Isobaric configuration, Volür produces deep, distortion-free low frequencies with unmatched texture and control. Six low-mid and one high-mid balanced armature drivers provide tonal richness and warmth, while a newly engineered tia high-driver with a waveguide delivers exceptional clarity and spatial detail. Housed in a refined matte black aluminum shell with a stunning Paua abalone faceplate, Volür blends visceral low-end impact with top-tier resolution across the spectrum.

Q&A Section
Q: What makes Volür different from other 64 Audio IEMs?
A: Volür introduces a dual dynamic driver True Isobaric configuration, offering unprecedented bass depth and precision in a UIEM format, while maintaining the signature 64 Audio tuning balance.
Q: How does the new isobaric driver setup work?
A: It uses two 9mm dynamic drivers linked by an acoustically inert chamber—one fully sealed—resulting in improved damping, lower distortion, and extended low-frequency response.
Q: What role does the new tia waveguide play?
A: The waveguide enhances HF driver efficiency and stereo imaging by optimizing sound dispersion through front and side diffusion windows.
Q: What kind of sound signature does Volür offer?
A: Volür delivers rich sub-bass, analog-style mids, and refined highs with excellent stereo imaging—ideal for immersive, musical listening experiences.
Q: Are apex™ modules included, and what do they do?
A: Yes, Volür comes with mX, m15, m20, and limited-time m12 modules that adjust air pressure and isolation, helping customize soundstage and comfort.
Q: How does LID™ affect performance across devices?
A: LID™ (Linear Impedance Design) keeps Volür's sound consistent whether you're using a smartphone, DAC, or high-end amplifier.
Q: Is the faceplate made from real abalone shell?
A: Yes, it features genuine Paua abalone shell responsibly harvested from New Zealand, giving each unit a unique, iridescent look.
Q: What’s included with the Volür?
A: You’ll receive the IEMs, premium case, full tip set, four apex modules (including m12 gold), black premium cable, and a collectible iridescent sticker.
