Acoustic Architectures
Tribrid Configuration
An advanced In-Ear Monitor (IEM) design that utilizes three distinct types of driver technologies simultaneously to cover the frequency spectrum. Typically combines Dynamic Drivers (for bass physical impact), Balanced Armatures (for mid-range clarity), and Electrostatic Drivers (for ultra-high frequency air).
Featured in: The Jewel (13-Driver Tribrid).
Coaxial Strong Magnetic Phase Pair
A proprietary Aroma Audio technology (Patent Pending) designed to eliminate the "muddy" resonance often found in dual-dynamic setups. By aligning two dynamic drivers on a single axis and reversing the magnetic polarity of one unit, we cancel out magnetic interference. This drastically increases the transient speed ("Q" value) of the bass response, allowing for thunderous impact with zero bleed.

Electrostatic Driver (EST)
A driver technology that uses static electricity to move an ultra-lightweight diaphragm. Because the diaphragm has almost zero mass, it can start and stop instantly, reproducing treble frequencies up to 80kHz with no distortion. Unlike traditional tweeters, EST drivers produce "Air" and "Holography" rather than just "Treble."
Materials & Metallurgy
6061-T6 Aerospace Aluminum
A precipitation-hardened aluminum alloy containing magnesium and silicon. We use the T6 temper (solution heat-treated and artificially aged) for our amplifier chassis. This material acts as a Faraday Cage, blocking Radio Frequency Interference (RFI) from smartphones, creating a "pitch black" background for audio signals.

Square-Core Conductor
A cable geometry where the internal wire strands are square rather than round. Square strands pack together tightly with no air gaps (unlike round wires), significantly increasing the conductive cross-section area. This reduces Skin Effect resistance at high frequencies, preserving treble detail and "Sparkle."
Featured in: Sparkle Cable.
Performance Metrics
Signal-to-Noise Ratio (SNR)
Measured in decibels (dB), this ratio compares the level of the music signal to the level of background noise (hiss). A higher number is better. At 129dB, the noise floor is effectively non-existent to the human ear, resulting in what audiophiles describe as a "Black Background."
