Jomo Audio Announces Global Debut of KOYO at CanJam Hong Kong 2026

April 16, 2026

Jomo Audio successfully participated in CanJam Hong Kong 2026 held last weekend, where the brand officially premiered its latest acoustic masterpiece — KOYO. The model made its first public demonstration and received widespread acclaim from audiophiles, industry professionals, and audio enthusiasts throughout the event.

Named to embody the refined beauty of natural foliage, KOYO is engineered as a premium tri‑brid in‑ear monitor that integrates advanced material science, precision acoustic design, and artisanal craftsmanship. It is built to deliver authentic, natural sound reproduction within an ergonomic, luxurious form factor.

The housing features a hand‑polished stabilized maple hardwood shell without glossy lacquer coating, preserving the wood’s natural porosity and acoustic resonance. This construction enhances organic reverberation within the cavity for warmer tonal balance and wider soundstage. The shell is paired with a brushed stainless steel frame and a CNC‑machined gold‑plated brass FlowMax open‑back grille, which optimizes airflow and sound dispersion for a spacious, non‑claustrophobic acoustic presentation.

At the core of KOYO is its sophisticated tri‑brid driver architecture:

10mm custom silk diaphragm dynamic driver for controlled, textured low‑end response
3 high‑precision balanced armature drivers for accurate midrange clarity and detail retrieval
6mm nano planar magnetic super tweeter for smooth, extended highs and excellent airiness

The system is supported by Jomo Audio’s proprietary AC2X Asymmetrical Co‑Axial Acoustic Chamber, constructed with graphene‑infused 3D‑printed resin for superior rigidity and damping. This structure effectively eliminates cross‑frequency interference between bass and ultra‑high frequencies, reduces internal resonance, and preserves sonic purity across the entire spectrum. A dedicated 4‑channel C.S.U. crossover circuit ensures seamless integration and smooth transition between drivers.

For signal transmission, KOYO comes equipped with a high‑end oil‑infused coaxial cable using OCC copper‑silver fusion conductors. The design minimizes signal loss, reduces capacitance and electromagnetic interference, and ensures faithful, low‑distortion audio delivery. The cable terminates in a high‑quality 4.4mm balanced connector, paired with a 0.78mm 2‑pin gold‑plated inner‑claw connector for stable connection.

With a frequency response of 20Hz–45kHz, impedance of 12.5Ω (@1kHz, 0.5Vrms), and sensitivity of 113.8dB (@1kHz, 0.5Vrms), KOYO offers effortless drivability and high‑fidelity performance for both portable and desktop use.

Throughout CanJam Hong Kong 2026, KOYO earned strong praise for its open soundstage, natural timbre reproduction, technical resolution, and long‑wearing comfort. Visitors highlighted its mature tuning, coherent tonal balance, and flagship‑grade construction as standout qualities.

Jomo Audio extends its sincere gratitude to distributor ECT for its support and to every visitor who experienced KOYO at the booth.

Following its successful premiere, KOYO will be officially launched globally in the near future. Stay tuned to Jomo Audio’s official channels for release dates, pricing, and full product availability.

Canpur CP752B Subjective Review: What a True Ultra-Flagship Should Be

November 24, 2025

Excerpt: Canpur CP752B – The Pinnacle of Ultra-Flagship Headphones

The Canpur CP752B, priced at $3,899.99, redefines what an ultra-flagship headphone should be—addressing the "compromise trap" plaguing many high-end models. Its unboxing experience exudes luxury: a ritualistic, museum-like interior with screw-on acrylic covers, paired with a premium ELETECH custom cable and soft leather case.

Beneath its polarizing "cement gray" medical-grade resin shell (optimized for comfort) lies a powerhouse driver setup: 7 BA, 4 electrostatic, 1 planar, and 2 bone conduction units, including Sonion’s groundbreaking G90 mid-high BA. Sonically, it delivers reference-grade performance—dense, immersive sound, a grand soundstage, and effortless resolution—yet is surprisingly easy to drive (7.6Ω, 102.7dB SPL).

Unlike its more mid-low focused predecessor, the CP622B, the CP752B balances robust bass with bright, extended mid-highs, feeling cohesive rather than disjointed. For audiophiles seeking a versatile, "endgame" choice, it’s a near-flawless option—just pair with warm front-ends like the Hiby RS8 for optimal musicality.

JOMO Audio Nautilus: Affordable High-Performance IEM

JOMO Audio Nautilus: Affordable High-Performance IEM

The JOMO Audio Nautilus, also known as "Nautilus," is a high-value in-ear monitor (IEM) that impresses with its steampunk-inspired design and powerful audio performance. Priced at $800, it shares the signature JOMO sound profile typically found in higher-end models like the GT600, but at a more accessible price point. The Nautilus uses an innovative driver configuration, featuring a 10mm DLC diaphragm dynamic driver for full-range sound, a 6mm planar driver for enhanced mid-high frequencies, and two bone conduction drivers to add texture and detail to the mids.

This IEM is especially suited for pop and live music genres, delivering a deep, immersive bass that creates a “stage-like” feel without overwhelming the mids and highs. The midrange is clear, detailed, and slightly forward, while the highs retain clarity and subtle resonance. Although the soundstage may not be as expansive for classical music due to the limited driver count, the Nautilus still offers excellent performance for its price. Overall, the JOMO Nautilus combines stylish design, innovative technology, and versatile tuning, making it a top choice for audiophiles looking for an affordable yet powerful IEM.
