Fosi Audio Disc Nano Portable CD Player with DAC & Headphone Amplifier
The Fosi Audio Disc Nano-B brings real CD playback into a genuinely portable format. At just 102 x 102 x 29 mm and 210 g, it is designed for listening on the go, on a desk or as part of a compact home audio setup. The half-exposed disc design keeps the spinning CD visible, while the snap-lock mount holds the disc securely during playback.
Inside, the Disc Nano-B uses a Cirrus Logic CS43198 DAC chip for precise conversion and supports CDDA, CD-R and CD-RW discs, with SACD playback possible when a CD layer is present. With a signal-to-noise ratio of at least 100 dB, THD+N below 0.0009% and a noise floor of 3 µV or lower, it is a compact option for listeners who value clean playback from physical media and high-quality DAC converters.
For headphone listening, the player offers both a 3.5 mm headphone output and a 4.4 mm balanced output. Output power is at least 86 mW + 86 mW into 32 ohms, and the compatible headphone impedance range is 16 to 300 ohms. This makes the integrated headphone amplifier suitable for a wide range of portable and hi-fi headphones.
The Disc Nano-B also works beyond direct headphone use. Bluetooth lets you send CD playback wirelessly to compatible headphones or speakers, while the 3.5 mm optical combo output allows it to function as a compact CD transport for an external desktop DAC. Its MagSafe-compatible magnetic design with an N52 magnet ring supports convenient magnetic placement on a mount, fridge or desk stand, with charging handled separately via USB-C at 5 V / 1 A.
