SNACK: 3-line summary
- AFUL has introduced MiracleOne, a wired in-ear monitor with compact transparent earpieces.
- Each ear uses one 6mm dynamic driver, with internal acoustic paths designed to shape treble and bass.
- The replaceable cable comes with a 3.5mm or 4.4mm plug; choose the version that matches your player or DAC.
AFUL’s new MiracleOne leaves its internal layout visible through small, transparent earpieces. This wired in-ear monitor houses one 6mm dynamic driver in each ear—the component that moves a diaphragm to produce sound.

Red I’d be turning those clear earpieces around just to trace the winding paths inside. I want a closer look at how it all fits.
Nea I’d like to revisit a favourite game soundtrack song with vocals and acoustic instruments. I’m curious how the voice and accompaniment would sound together on these.
Shaping the space around a single driver
MiracleOne uses a liquid silicone rubber (LSR) diaphragm. AFUL’s SEM design approach coordinates the driver’s characteristics, internal acoustic structures and electrical parameters.
According to AFUL, the front chamber’s stepped acoustic path and resonant microstructure are intended to shape treble response, while resonance tubes in the rear chamber tune bass. Driver count alone does not guarantee sound quality.
Match the cable plug to your player
The cable attaches to the earpieces through detachable 0.78mm 2-pin connectors, allowing it to be replaced. At the other end, HiFiGo offers 3.5mm single-ended or 4.4mm balanced plug options. Those sizes refer to the plug that connects to your player or DAC, not the connectors on the earpieces.
Choose the version that matches your device’s audio socket. To connect the 3.5mm version to a phone with only USB-C, you’ll need a separate compatible audio adapter or DAC.
HiFiGo currently lists MiracleOne at US$189.99, with a regular price of US$199.99. Shipping charges and taxes may apply.
