ThieAudio
Chinese IEM brand with solid measured performance via hybrid/tribrid designs. However, when compared strictly on measured performance alone, cheaper alternatives undercut it, and QC/support consistency remains a concern.
Overview
Founded in 2019 under Linsoul Audio, ThieAudio focuses on in-ear monitors across Voyager (multi-BA), Legacy (hybrid), and flagship tribrids combining DD + BA + EST. Notable models include Oracle MKIII (USD 589) and Hype 10 (USD 899). While they target high performance at accessible prices, consistency in QC and after-sales support warrants attention.
Scientific Validity
\[\Large \text{0.7}\]Independent measurements indicate broadly competent performance. Hype 10 shows avg. impedance 14.64Ω and sensitivity 133.9 dB/V SPL on RAA, with documented frequency-response shifts versus source output impedance (e.g., ~±2.8 dB at 40 Hz). Public THD datasets remain limited; available evidence suggests performance within practical limits, so we set this at 0.7.
Technology Level
\[\Large \text{0.8}\]High-end models employ IMPACT² (dual-isobaric bass) and reputable BA suppliers, with four-way crossovers and carefully tuned acoustic bores. Execution is competitive for the segment. Core transducer tech is sourced rather than developed in-house.
Cost-Performance
\[\Large \text{0.1}\]Ignoring driver topology and price class, we compare strictly on functionality (e.g., 0.78 mm 2-pin) and measured performance to the cheapest product that matches or exceeds those metrics. Among products with independently verified target compliance and low THD, the cheapest is TRUTHEAR x Crinacle ZERO: RED (USD 64.99) with Rtings-measured THD 0.04% @94 dB / 0.19% @104 dB and 115.7 dB SPL @1V sensitivity.
- Oracle MKIII (USD 589) → ratio 64.99 ÷ 589 ≈ 0.11
- Hype 10 (USD 899) → ratio 64.99 ÷ 899 ≈ 0.07
Average ≈ 0.09, so this criterion is 0.1 under strict measured-performance comparison.
Reliability & Support
\[\Large \text{0.4}\]Linsoul advertises a 1-year warranty, but user reports cite slow handling and challenging communication in some cases, alongside sporadic early defects. Prefer retailers with robust return windows and clear domestic support.
Rationality of Design Philosophy
\[\Large \text{0.8}\]Assigning DD/BA/EST to LF/mids/treble roles is a rational, measurement-driven partition. Crossover and acoustic path choices align with objective goals, though complexity can increase manufacturing tolerance and reliability risks.
Advice
If you want target-aligned tuning and modern multi-driver tech, ThieAudio can deliver. That said, a strict measurements-only comparison finds cheaper options (e.g., ZERO: RED) that meet or exceed key metrics. Mitigate support risk via strong-return retailers and confirm fit/kit requirements in advance.
