Fiio FF3S Authorized Store Number Intraconcave Type Earphones Dynamic Driver Lightweight Single Balance FIO-IEM-FF3S-B [Domestic Product/serial

FF3S is the latest model based on FIIO's intraconcave earphone FF3, which has been well-received for its uncompromising sound quality design, and has been significantly reduced in weight by changing the housing material, and is even easier to use with the use of a detachable cable. By combining FIIO's earphone development technologies such as a 14.2mm large-diameter driver, a newly designed drum-shaped housing, and the adoption of a sound pipe structure to enhance low frequencies, we have achieved a sound that breaks the conventional impression of intraconcave type earphones by expressing deep, sharp bass and glossy mid-high frequencies.
