FiiO JF11

Product information "FiiO JF11"
Wired earbuds 

  • Comfortable earphones, the earbuds are not inserted into the ear canal, but lie in the auricle, also suitable for side sleepers 
  • 14.2 mm dynamic driver for deep, dynamic bass 
  • U-shaped acoustic tubes, specially developed for bass reinforcement 
  • Membrane made of polyester fiber polymer composite for harmonious sound reproduction 

The FiiO JF11 is a wired earphone that impresses with its technical features and elegant design. 
Equipped with a 14.2 mm long-stroke driver, it delivers particularly deep and dynamic bass. 
This characteristic is supported by an innovative polyester fiber-polymer composite membrane that is lightweight yet extremely stable. 
Thanks to this choice of material and the precise tuning by FiiO's engineers, the earphones produce a crystal clear and harmonious sound reproduction with velvety, full voices that convey a touch of vintage charm. 
A special highlight of the FiiO JF11 are the U-shaped acoustic tubes, which have been specially developed for bass reinforcement. 
Inspired by the classic earbuds from Japan, this design combines acoustic sophistication with aesthetic elegance. By optimizing the diameter, length and angle of the tubes, the viscosity of the airflow is increased, lowering the resonance frequency of the sound chamber and improving bass quality. 
With a weight of only 14.5 g and an ergonomic design that is also suitable for side sleepers, the JF11 offers maximum wearing comfort. 
The compact design ensures that the earphones do not protrude from the ear and can be worn comfortably for long periods of time. 

14.2 mm dynamic driver 
Inside the FiiO JF11 is a large 14.2 mm dynamic driver with a long-throw design. 
This driver allows for a lower resonant frequency, resulting in deeper and more dynamic bass. It provides a solid acoustic foundation for high sound quality and low distortion, wrapped in a large soundstage. 

Polyester fiber polymer composite diaphragm 
The FiiO JF11 uses a polyester fiber polymer composite diaphragm for its dynamic driver. 
This diaphragm is not only lightweight, very stiff and low distortion, but also moderately damped and robust. 
Thanks to this diaphragm and careful tuning by the engineers, the JF11 offers a clear and smooth sound. 
Experience full voices with a charming vintage flair. 

U-shaped acoustic tubes for extended bass 
In the long history of earphones, the “U-shaped acoustic tubes for extended bass” are a notable design feature both in terms of sound quality and their distinctive aesthetics. 
Such a design was originally used in the AIWA HP-V14 earphones from Japan, which became popular worldwide and were highly appreciated by audiophiles. 

14.5 g weight 
The JF11 is a fully integrated design that does not require you to replace the cable. 
This makes it not only easy to store, but also convenient to take anywhere. With a weight of only 14.5 g, the JF11 is an absolute lightweight. 

Design that lets you fall asleep 
The JF11 has a design that lets you wear it lying on its side. 
The engineers at FIIO have reduced the size of the earphones as much as possible while ensuring excellent sound quality so that they do not protrude from the ear when worn. 

Naturally stylish 
black and gold - so that the FiiO JF11 perfectly matches your style.
