FiiO's FT3 Headphones are designed to masterfully harness energy for great sound. The showpiece of these headphones is the large 60mm dynamic driver, which is unique in its class. The large driver allows the diaphragm to move more air and convert energy into sound more efficiently, resulting in a natural and robust sound with a spacious soundstage.

The FT3's large dynamic driver also offers other benefits, such as the ability to carry higher output powers, reducing distortion in high-powered signals. Also, the larger driver can produce deeper bass for an impressive bass response.

The diaphragm is a critical part of the dynamic driver, which is why the FT3 opted for a beryllium-plated gasket in combination with a DLC diaphragm. The use of beryllium results in a lighter and stiffer gasket, better controlling driver movement and minimizing distortion. The DLC diaphragm is rigid and lightweight, resulting in less breakage and distortion, as well as an extended frequency response and improved sound reproduction.

With an impedance of 350Ω, the FT3 is designed to deliver pure sound. Higher impedance headphones filter out noise more effectively, resulting in a purer sound with a higher signal-to-noise ratio.

The FT3 also features a quality cable with interchangeable audio plugs and features a lightweight and strong aluminum construction for comfort and durability. The open-back design with a 3-axis pivoting design ensures a spacious soundstage and a snug fit. The FT3 also features angled drivers to promote better sound reproduction.

In short, the FiiO FT3 Headphones offer excellent sound quality with a wide dynamic range and a spacious sound image, thanks to the innovative driver and material choices. It is a versatile and comfortable headphone, suitable for lovers of high-quality sound experiences.
