KZ AM16 VS Astrotec GX100

The KZ AM16 is an all-BA in-ear monitor using 8 BA drivers per side (16 total) and offered in two editions—Balanced and Bass-Enhanced. Independent listings and user reviews confirm the per-side driver count, while KZ’s product page quotes a 5–45 kHz response and a standard 0.75 mm 2-pin cable; street pricing typically sits around $57.

Sonically, multiple reviews characterize the AM16 (Balanced) as a V-shaped tuning with a clear sub-bass lift and lively upper-treble, while keeping vocals reasonably intact. This yields engaging punch and sparkle, alongside detail retrieval and imaging that are competitive for the price.

Trade-offs are typical of all-BA bass: texture and slam are clean but less visceral than dynamic-driver peers, and dynamics can feel restrained on dense tracks. Sensitivity/impedance figures (≈104 dB, 22 Ω) make it easy to drive from portable sources; listeners wanting more low-end can opt for the Bass-Enhanced edition. Given its sub-$60 price and technical poise, it’s a strong budget pick, though its score should reflect its class rather than challenge higher-tier models.

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.
