CCZ CZ10 VS Astrotec GX100

The CCZ CZ10 (“TianGong”) is a budget hybrid IEM built around a 1DD+4BA array in a full zinc-alloy shell with 0.78 mm QDC 2-pin connectors. Street pricing hovers around $48–49, placing it squarely in the entry tier where build and configuration density are notable for the money. Specs and pricing are published by the retailer with sensitivity at 102 dB and 16 Ω impedance.

Tonally, the CZ10 presents a V-shaped balance with elevated sub-bass and some upper-treble lift relative to the mids, which can sound slightly recessed depending on tip and source. Frequency-response databases list the model and corroborate the bass/treble emphasis pattern typical of fun-tuned budget hybrids. Community impressions on Head-Fi characterize it as a generally balanced, easy-listening set with solid build for the price.

Technical performance is competent for this bracket: bass extension and punch are the clear strengths, while detail retrieval, imaging, and soundstage are serviceable rather than standout. Recent video coverage likewise frames the CZ10 as a value-oriented hybrid with engaging low end but only average staging and resolution—appropriate expectations at sub-$50.

The Astrotec GX100 is an entry-level hybrid IEM using a 10mm LCP dynamic driver plus a 10.6mm PZT piezo driver in a compact metal shell, targeting a Harman-inspired balance at an MSRP of around $49.90. It aims for a neutral-bright, clarity-focused presentation with relatively lean bass and elevated upper frequencies rather than a warm or bass-heavy profile, as reflected in multiple subjective impressions and store descriptions.

In practice, the GX100 offers good perceived detail and air for its price, with clear mids and crisp treble that benefit acoustic, vocal and lighter genres, supported by generally coherent integration of the PZT driver. However, the low-end is described as light in slam and sub-bass weight, and the energetic upper range can introduce fatigue or sharpness on brighter recordings, making tip selection and source pairing important to avoid overemphasis.

Technically, the GX100 delivers solid separation and micro-detail for a budget set, but its intimate stage, only moderate macrodynamics, and occasionally peaky treble position it as a niche choice rather than a class-leading all-rounder in the sub-$50 bracket. Considering the tuning compromises and strong competition at similar or lower prices, an overall evaluation should recognize its strengths in treble detail and hybrid implementation without overstating its value. This justifies a score that is competent for its segment but clearly below premium and upper-midrange benchmarks.
