The portable stereo radio FiiO RR11 brings back the timeless magic of FM listening, combining it with top modern sound technology. Designed around the renowned radio chip Silicon Labs Si4831, it offers extremely stable tuning, clear signal reception, and authentic high-fidelity (Hi-Fi) sound. All of this is integrated into a beautiful, ultra-slim aluminum alloy body just 13 mm thick and weighing only 46 grams, making it the perfect pocket companion.

One of the standout features of the FiiO RR11 is its exceptionally wide FM band coverage from 64MHz to 108MHz, divided into three alternating bands: FM1 (87-108MHz), FM2 (76-90MHz), and FM3 (64-87MHz). This makes the device compatible with broadcasting standards worldwide (Europe, Japan, China). The analog tuning wheel of the PVR type restores the nostalgic, manual experience, complemented by retro indicators for the frequency, stereo signal, and battery level.

Despite its tiny size, the FiiO RR11 hides inside a HiFi quality earphone circuit. The included JF11 earphones operate double as FM antennas, while the internal design of the circuit board (PCB) enhances the signal for top reception in real-world conditions. For an even richer and more immersive sound, it incorporates the analog chip DDB AS100, offering sound effects BASS+3D and functions MAGIC BASS, which provide incredible depth and intensity to music broadcasts, news, and talk shows.

What elevates the FiiO RR11 beyond a typical radio is its ability to function as a compact Headphone Amplifier via the analog USB Type-C input. In this mode (AMP mode), it delivers power up to 40mW + 40mW at 32Ω, with extremely low distortion (THD+N < 0.04%) and a top-notch signal-to-noise ratio (SNR ≥ 100dB). With adaptive impedance support from 8 to 100Ω, it can comfortably and clearly drive a wide range of headphones, transforming your phone or DAP into a high-end audio source.

Equipped with a rechargeable 300mAh lithium battery, the RR11 offers up to 8.5 hours of FM playback or up to 17.5 hours in amplifier (AMP) mode on a single charge. It supports playback during charging via USB-C, which takes approximately 2 hours to complete. The layout of the physical controls (band switches, mode, sound effect, volume/power rotary switch, and tuning) provides that unique, sturdy feel that only premium physical buttons can deliver.
