FiiO CP13 Portable Cassette Tape Player for Earphones

The CP13 is a portable stereo cassette player, currently the thinnest and most stable cassette player in production. It supports playing Type I to IV tapes. To ensure a stable movement, a customized large pure copper balance wheel with a diameter of 30.4mm and a thickness of 4mm has been selected, along with a high-voltage drive motor powered by 4.2V to maintain an extremely low oscillation rate, resulting in a more stable sound output.

Meticulous screening processes have been implemented to ensure stringent control over the entire production of CP13 magnetic heads, with the aim of minimizing the disparity between the left and right channels, surpassing the current standards of mass-produced models available in the market. Additionally, a balanced differential circuit design has been adopted for the acquisition of magnetic head signals, resulting in more stable signal transmission, higher signal-to-noise ratio, and lower distortion.

The CP13 is meticulously crafted with a dual-tone aluminum alloy shell, featuring a seamless design with no visible screws on the body. The buttons are treated with a hardened oxidation process, ensuring durability and resistance to wear and corrosion. The volume knob of the aluminum alloy is designed with a large-volume analog volume potentiometer, which is more stable and reliable in quality compared to the flat potentiometers used in ordinary cassette players, providing a better tactile feel for adjustment.

Featuring the renowned JRC5532 operational amplifier, the CP13 is powered by an 1800mAh lithium cobalt oxide battery, providing over 13 hours of continuous playback for extended listening sessions.
