⚙️ Technical Breakdown

Driver Configuration: 10mm dynamic driver with passive radiator system

The dynamic driver handles the full frequency range, delivering a coherent and natural sound.

The passive radiator reacts to internal air pressure, enhancing bass behaviour without adding distortion.

This results in improved bass texture, speed, and physicality compared to traditional single-driver designs.

The system behaves more like a speaker setup, giving the EA1000 a distinctive and realistic low-end presentation.

Impedance: 16 Ω

Sensitivity: 127 dB

Drive Difficulty: Easy to Moderate

Works well with dongle DACs but benefits from higher-quality sources.

🔧 Tuning Options (Nozzle System)

The EA1000 includes interchangeable tuning nozzles that allow you to meaningfully adjust the sound profile.

🎯 Balanced Impact Nozzle (Default – Silver with Red Ring)

Delivers the intended tuning with strong bass presence, smooth treble, and a balanced, musical presentation.

⚖️ Reference Clarity Nozzle (Silver with Black Ring)

Enhances midrange and treble clarity, providing a cleaner, more detailed and analytical presentation.

✨ Open Air Nozzle (Gold with White Ring)

Increases openness and air, delivering the most spacious and energetic sound profile.

These changes are clearly audible and allow the listener to tailor the experience without altering the core identity of the IEM.

🔌 Compatibility & Source Guide

Works with laptops, PCs, and devices with a headphone jack.

For phones without a jack, use a USB-C or Lightning DAC.

Easy Start — Dongle Tails: Compact DAC devices that plug directly into your phone.

Upgrade Path: More capable DAC/amps can improve clarity, bass control, and dynamics.

All options will work — the difference is how much performance you want to unlock.
