Overview

The final E1000 is a 6.4 mm single dynamic IEM rated 16 Ω / 102 dB/mW with a lightweight ABS shell and swing-fit ergonomics. It targets a neutral presentation and runs easily from phone or laptop outputs［1］. Japan release: Nov 30, 2018［5］.

Scientific Validity

\(\Large \text{0.5}\) Independent frequency-response data exist on an IEC60318-4 coupler (In-Ear Fidelity)［2,3］. Public lab-grade data beyond FR (e.g., THD, isolation) are limited, so the evidence base is moderate rather than comprehensive.

Technology Level

\(\Large \text{0.4}\) A small 1DD + ABS build with a fixed OFC cable prioritizes comfort and practicality. In 2025, this is competent but unremarkable, lacking novel diaphragm materials or advanced acoustic structures［1］.

Cost-Performance

\(\Large \text{0.8}\) US/global street: E1000 about 29.99 USD (retail example). A widely available alternative with equal-or-better measured tonality, 7Hz Salnotes Zero, is 22.99 USD; ratio ≈ 1.30—indicating the E1000 is price-pressured globally［4,9–11］.

Reliability & Support

\(\Large \text{0.6}\) Final provides a 1-year warranty via authorized dealers and clear after-sales information. No aggregate failure-rate statistics are published; coverage is industry-standard［1,4］.

Rationality of Design Philosophy

\(\Large \text{0.6}\) A neutral, fuss-free tuning and easy fit reflect sound engineering priorities［1］. The approach remains sensible, though differentiation is thinner as newer sub-30 USD IEMs better track targets.

Advice

• Pick E1000 for lightweight comfort and restrained tonality, especially if buying in Japan.
• Prefer 7Hz Salnotes Zero (22.99 USD) for closer-to-target FR at lower global pricing［9–11］.
• Consider Moondrop CHU II (≈¥4,950 JP) if you want Moondrop’s house tuning and 2-pin recabling［8,12］.
• Want a more V-shaped fun sound? CCA CRA remains popular, but its tonality deviates more from neutral［13］.
