AriaEar Spark redefines high-frequency reproduction with Sonion electrostatic tweeters capable of vibrating up to 100,000 times per second. Coupled with precision Knowles balanced armature drivers for rich, tactile midrange and a fast low-frequency motor, Spark delivers an ultra-wide frequency response with total harmonic distortion (THD) under 0.08% at 1kHz. Experience effortless, distortion-free air and micro-details that transcend conventional dynamic and planar IEMs.
Engineered with 0.02mm-tolerance 3D internal acoustics, our proprietary Direct Sound Resonance System (DSRS) synchronizes acoustic phase waves from electrostatic and balanced armature drivers into a unified wavefront. Each Spark faceplate is uniquely hand-oxidized using natural patina chemistry inspired by historic European cathedrals, ensuring that no two pairs are visually identical.
Engineered over 7 years of relentless acoustic research, Spark delivers reference-grade transparency, effortless dynamic swings, and an expansive 3D stage where every instrument occupies its own three-dimensional space.

Spark incorporates custom miniaturized step-up transformers inside the earpiece. This converts standard audio line voltages into the electrostatic bias required to drive the EST membrane, giving you true electrostatic treble extension without bulky external energizers or specialized amplifiers.
Each Spark faceplate undergoes a proprietary multi-stage chemical oxidation process that creates distinct turquoise, emerald, and bronze patina mineral formations. Because the oxidation reaction forms naturally on the raw copper, every single pair of Spark IEMs is a one-of-a-kind art piece.
Spark comes standard with a bespoke 7N ultra-pure OCC (Ohno Continuous Cast) copper coaxial cable with gold-plated 0.78mm 2-pin connectors and low-loss dielectric shielding for immaculate signal purity and near-zero crosstalk.
