Single Balanced Armature In-Ear Monitors - FA1

A transparent look into the extraordinary

The FA1’s arresting ripple texture faceplate is complemented by an equally stunning transparent body, allowing you to marvel at design and care that went into every detail of the in-ear monitor’s design.

The balanced armature drivers in the FA1, in conjunction with the specially designed micrometer sound tube, have been tuned to provide a natural yet smooth sounding frequency response, free from any dips or peaks. With the FA1, you will get robust yet quick bass, wonderfully rich mids, and treble dripping with detail and speed that only balanced armature drivers can provide.

Smooth, velvety yet precise balanced armature sound

The FA1 is created with advanced industrial-grade 3D printers utilizing DLP printing technology with resolution up to 25um. Compared to traditional molding or injection molding processes, 3D printing in conjunction with sophisticated digital modeling allows us to achieve more unit-to-unit consistency and better overall sound.

Unparalleled precision from cutting-edge 3D printing

Customized Knowles driver for mesmerizing sound, every time

Inside the FA1 is a specially-customized balanced armature driver co-developed by FiiO and Knowles that especially capitalizes on the strengths of BA drivers for excellent sound. And with its low 15-ohm impedance you can be sure the FA1 will sound good out of anything, even from your phone!

Choosing the perfect outer shell

The outer shell of the FA1 employs a skin-friendly resin material, specifically chosen for maximum wearing comfort and for its ability to durably retain its color and luster for years to come.

Included with the FA1 are a waterproof carrying case, a cleaning brush, ear tips optimized for bass (3 pairs), and ear tips optimized for a balanced sound signature (3 pairs) so that you are immediately ready to listen the way you want to.

The attention to detail starts with the accessories

Democratizing great sound for the common person

FiiO has never been about making greedy amounts of profit – rather, we aim to provide great sound that is actually affordable for the common person. With the FA1’s Knowles BA driver and state-of-the-art 3D printing process, we continue that tradition of producing excellent-sounding great value products.

The shape of the FA1 was designed from the input of tens of thousands human ear shapes, to ensure maximum comfort and that the sound flows unimpeded to your ears.

Honed by thousands of ears

Thanks to advanced 3D printing technology and the skin-friendly resin material of the shell, a single FA1 ear unit weighs in at a mere 4.5g for unparalleled wearing comfort.

Light as a feather

Detachable cables for unleashed sound

Not only does the included MMCX cable enhance the durability of the FA1 by making it easy to replace, it also enhances the sound you get. The included 3.5mm-terminated cable is made of oxygen-free copper-plated silver wire for supreme clarity and a vast soundstage.
