The FiiO RR11 is a pocket-sized stereo radio designed for listeners who enjoy classic FM with modern flexibility. Its ultra-thin 13mm aluminium body feels solid yet light in your hand, slipping easily into a pocket for commuting or travelling. The analogue-style PVR tuning wheel lets you physically scroll through stations, giving you that tactile connection digital tuners often lack. Inside, the dedicated Si4831 FM chip and specially designed HiFi circuit work together to deliver clear, stable reception with a natural, balanced sound.
With support for an ultra-wide 64–108MHz FM band, you can tune into everything from local news to campus broadcasts around the world. A built-in PCB antenna strengthens reception, even in such a compact design. The 300mAh battery provides over 8.5 hours of playtime, and you can listen while charging for added convenience. Switch to amp mode with the included cable to power your headphones and unlock BASS and 3D sound effects, giving your music extra depth and energy when you want it.
