Dual Knowles BA Earphone FH1s

Knowles 33518 Balanced Armature | Large 13.6mm dynamic driver | Balanced pressure relief technology

Friendly HiFi tuning for popular music | High purity monocrystalline Litz copper cable | Unique celluloid faceplate

On a never-ending quest for improvement

The FH1S is a newly developed earphone that takes as a base the original FiiO FH1, itself highly acclaimed by many in the audio community, and further improves the sound to greater heights. Compared to the FH1, the FH1S has a bigger and improved dynamic driver combined with a Knowles balanced armature driver for truly deep and revealing bass, astonishingly clear mids and highs, and truly moving lush vocals. 

Knowles 33518 balanced armature driver

For exceptional treble and sweet vocals

The FH1S’Knowles 33518 BA driver is located near the front (closer to the ear) of the body, which reduces high-frequency sound loss and thus improves treble extension. The Knowles BA drivers plays its high frequencies through a brass sound tube, which reduces unwanted resonances and gives the higher frequencies a sense of realism and tactility you can really feel.

Large 13.6mm dynamic driver

Excellent low-frequency transient response and low distortion

The FH1S’ dynamic driver is made of a bio-polymer diaphragm being driven by extremely robust N50 magnets, giving you powerful yet quick bass as well as crisp and clear drums for a striking overall sound.

· Brass vibration-damping ring · Bio-polymer diaphragm · Strong N50 magnets

·Acoustic suspension system· 5Hz-40KHz frequency response · Balanced pressure relief technology

Precisely tuned balanced pressure relief technology

While the large 13.6mm dynamic driver on its own provides high quality deep bass, when combined with our patented balanced pressure relief technology we unlock even more of that driver’s potential! The precisely tuned balanced pressure relief system equalizes the air pressure in the front and the back of the body, greatly enhancing the soundstage and reducing your ear’s fatigue when listening. 

Love at first sight

Celluloid has been widely used for making guitar picks and itself has innate musical properties. Layered celluloid is also the material of choice for the FH1S’ distinctive faceplate. Due to the randomness of the layered celluloid each FH1S faceplate has its own distinctive look, literally giving each FH1S its own unique personality. 

Not just beautiful on the outside

Custom-IEM grade ergonomics

Based on the feedback received for FiiO’s other IEMs, we have made the FH1S even more like a custom IEM for truly excellent comfort. After going through countless iterations of different designs, we settled on a shape that more closely follows the shape of the human ear, allowing anybody to put on the FH1S more easily and wear it more comfortable for longer periods of time.

Specially-tuned sound everybody will love

Rich bass, transparent treble, and beautiful vocals

The FH1S adopts a sound signature that both audio enthusiasts and mainstream listeners will love. With vivid bass, clear treble, and lush vocals, the FH1S’ relatively balanced sound signature will find fans of all kinds.

Easily driven even by your phone

Due to the high sensitivity of the balanced armature unit, even ordinary phones allow you to fully enjoy the FH1S’ warm, yet transparent nature. 

·Impedance 26Ω ·Sensitivity 106dB

120-core high purity monocrystalline copper cable

0.78mm 2-pin connectors

Included with the FH1S is a custom-made cable made of 120 braided individual high purity monocrystalline Litz wires. Each Litz wire is insulated from each other, ensuring better audio transmission performance under the naturally-occurring yet adverse skin effect. What this means for actual listening are improved bass and mids, as well as more coherency between all audio frequencies.

True wireless upgrade

Transform it into earphones perfect for workouts

With the UTWS1 true wireless Bluetooth module (0.78mm 2-pin edition), you can transform the FH1S to be a true wireless headset in seconds. With support for TWS+ technology and the high-definition aptX Bluetooth audio format, the UTWS1 is the perfect partner to the FH1S to give you the convenience of true wireless, without sacrificing sound quality.

    Buongiorno, le cuffie hanno un suono meraviglioso e sono comodissime, ma a soli 2 mesi dall\'acquisto il cavo a 2 pin 0.78 mm si sta già rovinando, l\'intreccio dei fili si sta aprendo. Volevo sapere se è possible acquistare separatamente il cavo originale, o se esiste un modello sostitutivo o di aggiornamento. Grazie.
