An artisanal jewel of picturesque sound

Single Balanced Armature In-Ear Monitors - FA1

DLP 3D Printed | Specially customised balanced armature driver | Detachable MMCX cable | Light and comfortable | Democratising affordable excellent sound

Unparalleled precision from cutting-edge 3D

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

Customised Knowles driver for mesmerising sound, every time

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

Smooth, velvety yet precise balanced armature sound

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. 

A transparent look into the extraordinary

The FA1's arresting ripple 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.

Honed by thousand of ears

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. 

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 ouster for years to come. 

Light as a feather

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.

Detachable cables for unleashed sound

Not only does the included MMCX cable enhance he durability of the FA1 by making it easy replaceable, 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. 

Democratising 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 attention to detail starts with the accessories

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

Fiio FA1 una piacevole sorpresa e di qualità

Dopo circa un mese di utilizzo insieme ad un altro autentico gioiello il fiio utws3 posso affermare che sono molto comode da indossare anche per sessioni lunghe. Suonano bene e anche l'utilizzo accoppiato al telefono per necessità non ludiche si è rivelato di grande qualità. Al prezzo a cui vengono proposte sono una grande occasione di acquisto. L'abbinamento con il modulo utws3 si è rivelata fantastica.
