Know before you buy
Effect Audio designed the Axiom with sustainability in mind, encouraging users to reuse existing high-quality cables they already own. This approach reduces waste and allows you to pair the monitors with a cable that perfectly matches your personal sonic preferences.
The MU system features interchangeable modules that allow you to swap between MMCX and CIEM 0.78mm 2-pin connectors. This ensures the Axiom remains compatible with your current cable collection without needing adapters.
The Axiom utilizes a 12mm magnesium dynamic driver for rich lows and mids, paired with dual Knowles balanced armatures for clear highs. This combination delivers a reference-class, non-fatiguing sound that remains balanced and engaging across a wide variety of musical genres.
Yes, the Axiom features an ergonomically shaped shell and nozzle designed to sit securely and comfortably in the ear. Combined with its lightweight 10.2g build, it is specifically optimized for extended use without causing ear fatigue.
With an impedance of 32Ω and a sensitivity of 112 dB/mW, the Axiom is relatively efficient and can be driven well by most modern smartphones, tablets, or portable digital audio players. While a dedicated amplifier can further refine the performance, it is not strictly necessary for a great listening experience.
The proprietary RC architecture manages the transition between the dynamic driver and the balanced armatures at 4,800 Hz. This ensures a seamless frequency response and prevents the harshness often found in poorly integrated hybrid designs.
