FiiO RETRO BOX Desktop Bluetooth Speaker BLACK

The FiiO RETRO BOX is a cassette-inspired desktop Bluetooth speaker designed as a companion for FiiO JM21, M21 and M33 series music players. Its retro enclosure incorporates a removable mounting system that allows compatible FiiO players to sit directly inside the speaker, creating an integrated desktop listening setup. The music player is sold separately.

A dual-chamber acoustic design combines two 40 mm full-range drivers with two passive radiators. The drivers are positioned toward the sides of the enclosure to create a wider, more balanced sound field, while the dual-channel amplifier delivers 5.3 watts per channel.

Bluetooth 6.0 provides wireless playback with SBC and high-resolution LDAC codec support. The RETRO BOX can also connect directly to a desktop or laptop computer in USB DAC mode, with driverless UAC 1.0 operation supporting 44.1, 48 and 96 kHz sampling rates at up to 32-bit resolution.

Two internal 18500 batteries provide approximately 10.5 hours of playback under FiiO's stated test conditions. A built-in DSP offers HiFi, Retro, Pop and Warm sound presets, while the FiiO Control app provides custom EQ adjustment, Bluetooth codec selection and firmware updates.
