HZSOUND Crystal
The HZSOUND Crystal is a 1DD + 1BA hybrid in-ear monitor designed to deliver refined high-fidelity performance at an accessible level. Featuring a proprietary dynamic driver with a PU + LCP hybrid composite diaphragm, a custom balanced armature unit, dual physical and electronic crossover network, and a stainless steel faceplate with E.M.F. shielding, the Crystal offers two carefully tuned versions — Balanced and High-Res — to suit different listening preferences. Paired with a high-purity 100-core silver-plated OFC Litz cable and 0.78mm 2-pin connectors, it provides a clean, detailed, and highly scalable sound signature suitable for both portable and desktop sources.
Stainless Steel Faceplate with E.M.F. Shield
The Crystal adopts a stainless steel faceplate integrated with an E.M.F. shield design. This construction not only enhances structural rigidity and premium aesthetics but also helps reduce external electromagnetic interference, contributing to a cleaner signal path and more stable sonic performance.
Proprietary Dynamic Driver with Rigid Composite Diaphragm
At the core of the Crystal is a proprietary dynamic driver featuring a rigid PU + LCP hybrid composite diaphragm and an ultra-lightweight CCAW voice coil. This combination delivers fast transient response, controlled bass, and improved overall resolution while maintaining natural timbre and low distortion across the frequency range.
Dual Physical and Electronic Crossover Network
A precise dual physical and electronic crossover network ensures seamless transition between the dynamic driver and balanced armature unit. Critical frequencies are handed over with exceptional smoothness, minimizing phase discontinuities and the disjointed character sometimes found in hybrid designs, resulting in a continuous and natural overall presentation.
Two Meticulously Tuned Versions
The Crystal is available in two distinct tuning options. The Balanced version offers even, all-round tonal balance with controlled energy across the spectrum, making it versatile for pop, rock, electronic, hip-hop, R&B, and everyday mixed playlists. The High-Res version prioritizes detail retrieval, spatial air, and micro-dynamic nuance, excelling with acoustic, classical, jazz, chamber, and well-recorded vocal or instrumental tracks.
Resolving Timbre and Vocal Transparency
The custom balanced armature unit provides excellent resolution and clarity to vocals and instruments. Lip and breath details are rendered with precision, while harmonic overtones of strings and the natural attack of piano remain intact, producing a presentation that feels both analytical and musically involving.
High Sensitivity and Excellent Scalability
With high sensitivity (108 ± 3 dB) and moderate impedance (20 Ω ± 15%), the Crystal extracts strong performance from smartphones, dongles, laptops, and DAPs. It remains dynamic and engaging even on portable sources while scaling meaningfully when paired with higher-quality equipment.
High-Purity 100-Core Silver-Plated OFC Litz Cable
The Crystal comes with a high-purity 100-core silver-plated OFC Litz cable featuring enhanced geometry and reliable 0.78mm 2-pin connectors. The flexible sheathing reduces microphonics and resists tangling while preserving clean signal transmission and long-term durability.
