TRUE-TO-LIFE
SOUND EXPERIENCE
Equipped with ultra-sensitive microphone capsules on each side, the BIEM (Binaural In-Ear Microphones) captures immersive 360° soundscapes that mirror how human ears perceive the environment. Unlike traditional stereo recordings, this approach places listeners in the center of the soundstage, delivering a lifelike spatial audio experience
UNOBTRUSIVE
PRECISION AUDIO MONITORING ANYWHERE
No need for separate mics and monitors. Seamlessly record immersive 360° sound while hearing it in real-time. The in-ear monitor system features a hybrid driver setup, a single dynamic driver with improved quality and less driver flex problem, and a single-precision Balanced Armature Driver per channel with true crossover circuitry, delivering rich, detailed sound reproduction, all in a comfortable, ergonomic open vent shells design that fits naturally in the ears.
CUSTOM-CRAFTED
AUDIO CABLE DESIGN
Made for uncompromising clarity and immersion namely Magni C4. Its 4-braid Litz coaxial architecture uses ultra-pure OFC copper with a 28.7 AWG core and a 26.1 AWG shield for superior signal integrity and noise rejection. Outfitted with Verus bespoke components—including precision soldering, a custom Y-split, IEM connectors, and dual 3.5mm gold-plated brass plugs—Magni C4 blends technical refinement with flexible durability for the ultimate listening experience.
NEW DIMENSION
OF SOUND
Binaural recording with a binaural microphones captures audio the way we naturally hear it—spatial, directional, and immersive. Unlike standard stereo, it creates a true 3D sound experience through headphones. BIEM empowers creators to record the world with stunning realism and creative freedom in a compact, wearable form. Ideal for recording live music concerts, podcasts, vlogs, ASMR, Foley effects, field recordings, video conferencing, and more—transporting listeners directly into the captured environment.
