The name "FEI WAN" is a phonetic play on the nickname of the founder of AROMA Audio, symbolizing a new chapter and a significant step forward. More than just a new product, "FEI WAN" represents a newly established sub-brand under AROMA Audio.

"FEI WAN" is composed of 10 balanced armature drivers and 2 dual 9.2mm dynamic drivers. In addition to the commonly used 10 balanced armature drivers, this model incorporates a novel patented technology known as "Coaxial Strong Magnetic Phase Pair Double Dynamic Drivers Technology." The design enhances both sound density and dynamics through the combination of ten balanced armature drivers and the newly developed dual dynamic drivers.

The core of the Coaxial Strong Magnetic Phase Pair Double Dynamic Drivers Technology lies in the reverse magnetization of one of the dynamic driver units (with opposing magnetic poles) and the inversion of the coil's positive and negative terminals. This configuration allows the two dynamic driver units, when aligned coaxially and face-to-face, to avoid magnetic interference from each other, thereby improving the overall Q factor of the combined units.

The cabling features AROMA Audio’s “Sparkle” design, utilizing 0.78mm 2-pin connectors and 4.4mm termination. Made from high-purity, silver-plated, oxygen-free copper, the "Sparkle" name reflects our belief that this upgraded cable brings vibrant color to IEM products, enhancing the sonic performance with a glossy finish. It’s not only suitable for AROMA Audio’s IEMs but also showcases excellent performance across various models.

The housing is crafted using 3D printing technology, maintaining a near-CM design. After years of experience with ear shell designs, we have fine-tuned the shape and size to enhance stability and comfort when worn.

The overall sound orientation of "FEI WAN" features a distinct three-band balance. With years of experience in developing hybrid driver systems, the interaction of multiple balanced armature and dynamic drivers does not detract from each other's output. The resulting sound has high separation, excellent vocal extension, and precise sound staging, making it capable of handling both pop music and large orchestral compositions with ease.

"FEI WAN" marks a significant new step forward.
