Ultra-compact FM stereo radio with analog tuning dial, specialty Si4831 FM chip, dual power modes, Magic Bass + 3D sound effects, built-in antenna, retro lighting, headphone amp mode and included earbuds & USB-C cable — a modern nod to classic radio style with versatile audio functions.

The FiiO RR11 is a stylish portable FM stereo radio that blends nostalgic analog radio experience with modern audio versatility. Housed in an ultra-thin aluminum alloy body that’s just about the size of a lighter, the RR11 brings back the tactile feel of classic radios with a physical PVR-style tuning wheel that lets you scroll through FM frequencies with satisfying mechanical feedback. Its specialty Silicon Labs Si4831 FM radio chip provides clear, stable reception across a wide FM range from 64–108 MHz, letting you enjoy mainstream broadcasts, campus stations and local programming anywhere FM is available.

Beyond traditional radio, the RR11 includes a high-performance built-in PCB antenna that enhances reception while still allowing headphone cables to serve as an auxiliary antenna. Its Hi-Fi-tuned analog circuit delivers warm sound, and the dedicated Magic Bass + 3D sound effect chip lets you boost low frequencies or add a spatial effect for more immersive listening.

The RR11 is powered by a rechargeable 300 mAh battery offering hours of reception and playback, plus dual power modes that let you use it while charging. In addition to radio, the included retro-style earbuds and Type-C to analog cable let the RR11 function as a portable headphone amplifier when connected to smartphones or portable players, unlocking richer output and a unique analog sound signature.

Retro lighting indicators make tuning, stereo mode and battery status easy to read, while the slim form factor and multiple colour options make the RR11 both a functional receiver and a stylish everyday companion.
