Founded in 2007, FiiO is a manufacturer focusing on lossless music players, headphone power amplifiers, headphones and other audio products. Since FiiO mainly makes audiophile audio equipment, its players are on the large side in sports MP3, and the portability is slightly insufficient, which is suitable for users who have a high pursuit of sound quality.
 
With its excellent product design, FiiO has obtained a number of valid patents in the field of acoustics, and its products have won hundreds of well-known awards such as the IF Design Award, the Red Dot Product Design Award, the European Audio-Visual EISA Award, the Japanese VGP, and the Spring and Autumn Headphone Festival Awards.
 
In the field of sports MP3, FiiO's products are mainly portable HiFi players, and FiiO's product line is also relatively rich for different consumers. From the student market to the professional market, FiiO's products have always had good competitiveness at home and abroad. The product line is divided into X series and M series, the larger the number after X, the more high-end, it is worth mentioning that the X series has undergone many iterations, and it will be confusing to follow the name of the series, so for the sake of brand naming, future players will be named after M.
 
In the "Best MP3 Player" selection of the evaluation website Bestproducts, FiiO X1II ranked third, with a price of 600-700 yuan. It is the world's largest selling Chinese brand Hi-Res HD lossless player, smaller than most mobile phones, weighing about 100g, supporting Bluetooth, memory expansion, remote control and deep standby and other functions. The X1II's sound quality performance is an entry-level benchmark, with a trendy style and support for most mainstream music formats, but it also has the same drawbacks, such as the touch dial not as timely as the button feedback, and poor control in motion.
 
FiiO also has a more compact M3K option, it ranks fifth in the MP3 evaluation of the well-known evaluation website alaTest, priced at about 350 yuan, equipped with Ingenic X1000E main control, compared with the integrated main control at the same price, it has lower power consumption and higher performance, normal battery life can reach 24 hours, and supports 12 mainstream music formats, supports 2TB memory expansion, repeat and recording functions, but there is no Bluetooth. Overall it's good value for money, making it ideal for students on a budget.
