The innovative dual magnetic circuit design enhances dynamic range and control, offering bold, responsive playback that redefines what a single-driver IEM can achieve—ideal for audiophiles who demand both clarity and excitement in every note.

DUAL-LAYERED TITANIUM DIAPHRAGM FOR PURE & FAST TRANSIENTS

The SPA-Hi End houses a Titanium Gold Ball Top diaphragm with silicone suspension for ultra-fast response and superior rigidity. This advanced material delivers crisp attack and minimizes unwanted resonances, ensuring every detail is reproduced with exceptional clarity. The double-sided composite structure enhances both durability and sonic accuracy, making it ideal for high-resolution listening.

TUNED FOR EVERYDAY ENJOYMENT

The SPA-Hi End features a mild V-shaped sound signature- expect a lively boost in both bass and treble, while the Mids remain present but slightly relaxed for a dynamic and engaging listen. This tuning delivers punchy low-end impact and crisp, airy highs, making every genre sound vibrant and detailed. Vocals and instruments retain clarity without being overshadowed, so you get a fun, energetic presentation that never feels fatiguing. Ideal for rock, pop, EDM, and anyone who loves a bit of extra excitement in their music

PREMIUM COPPER CABLE FOR CRISP & RELIABLE SOUND

The EarAcoustic SPA-Hi End comes with a premium detachable cable featuring 0.78mm dual-pin connectors for secure and easy replacement. Crafted from oxygen-free copper and silver-plated wire, this cable ensures optimal signal transmission with minimal loss and interference. Its durable yet flexible construction provides tangle resistance and long-lasting reliability, making it perfect for daily use. The 1.2-meter length offers freedom of movement while maintaining a neat setup, and the 3.5mm termination plug enhances both convenience and audio performance.

ELEGANT DESIGN WITH ROBUST BUILD

The SPA-Hi End showcases a striking faceplate and shell crafted using 3D resin printing, finished with a refined sub-bright silver spray for a sophisticated, contemporary look. The seamless integration of the faceplate with the shell not only enhances visual appeal but also contributes to the IEM’s robust construction. Every curve is engineered for durability and style, delivering a premium tactile experience that stands out in any collection.

COMFORT THAT KEEPS YOU LISTENING

The EarAcoustic SPA-Hi End is designed for extended listening sessions without fatigue, thanks to its ergonomic shell that fits snugly and securely in the ear. While the single 11.4mm dynamic driver results in a slightly bulkier build compared to typical resin IEMs, the thoughtful design ensures comfort even during long hours of use.
