FiiO RR11 Black - Portable Hi-Fi stereo radio

Built into a 13 mm aluminium frame weighing just 46 g, this radio features a Hi-Fi circuit that pairs analogue PVR tuning with a Silicon Labs Si4831 chip, delivering clear reception over the 64-108 MHz range. Thanks to the BASS/3D selector, analogue filters boost low frequencies and widen the soundstage, while the 300 mAh battery provides as much as 8.5 h in FM or 17.5 h in amplifier mode.

Retro styling and metal build

The machined alloy housing reduces vibrations, features vintage LED indicators and shields the integrated antenna; the front wheel delivers accurate tactile response when turning the dial.

Ultra-wide Hi-Fi Tuner

The Si4831 spans global bands and, alongside the PCB antenna booster and the ability to use the headphone cable as an extension, keeps S/N >45 dB and distortion 100 dB and zout of 1 Ω, able to drive most IEMs without noise. The digital-to-analogue cable is supplied in the box together with the vintage JF11 headphones.

BASS and 3D + battery modes

The side switch provides two profiles: Magic Bass 1 adds punch; Magic Bass 2 introduces a 3D effect without sacrificing clarity. The battery can be used while charging and reaches full charge in roughly 2 hours via 5V/1A.

Comparison

The FiiO RR11 restores the joy of the analogue dial with benefits its direct rivals lack. Next to the Sony SRF-18 and Sangean SR-35, it offers DAC/AMP mode, BASS+3D effects and a longer-lasting rechargeable battery, all within a slimmer, lighter body. It has no built-in speaker or AM band, yet its power-balanced output and its ability to work as a USB dongle make it excellent value for anyone after a portable Hi-Res radio that also drives their headphones. The FiiO RR11 therefore shows that a classic format can meet modern audio demands without inflating the price.
