FiiO RR11 Portable FM Radio with USB DAC Mode

OverviewA phone can stream almost any station over the internet, but a dead zone, a dead battery, or just the simple pleasure of turning an actual dial can make a dedicated radio worth having again.The FiiO RR11 is a pocket-sized FM radio built around a Silicon Labs Si4831 tuner chip and a custom FiiO "DDB" analog amplifier chip, tuned by hand with an analog wheel rather than a digital menu. It covers three FM band ranges (87-108MHz, 76-90MHz, and 64-87MHz), which between them cover standard broadcast, Japan, and school-campus frequency ranges, with a built-in antenna backed up by the headphone cable itself acting as a secondary antenna.A USB-C port doubles as a digital audio input, so the RR11 can also work as a small USB DAC and headphone amplifier for a phone or computer, adapting automatically to headphones between 8 and 100 ohms. A 300mAh battery runs up to 8.5 hours in radio mode or up to 17.5 hours in amp-only mode, in an aluminum alloy body that weighs about 46 grams.Simcoe Audio Video InsightThe RR11 ships with FiiO's own JF11 earbuds, which double as the antenna when plugged in — leaving them unplugged or swapping to a cable without enough length can noticeably weaken FM reception in a marginal signal area, since the radio's built-in PCB antenna alone isn't the primary antenna path. The USB-C DAC mode is a nice bonus for anyone who wants a tiny dedicated amp for a phone or laptop when the radio side isn't in use.More InfoWhy the FiiO RR11 Stands Out Three-Band FM Tuning Covers 87-108MHz, 76-90MHz, and 64-87MHz, spanning standard broadcast, Japan, and school-campus FM ranges from a single tuner. Analog Tuning Wheel A physical tuning wheel gives tactile, manual station selection instead of a digital menu to scroll through. Dual-Mode Radio and USB DAC The same USB-C port that charges the RR11 also accepts a digital audio signal, letting it double as a small USB headphone amplifier for a phone or computer. Up to 17.5 Hours in Amp Mode Battery life stretches to 17.5 hours when used purely as a headphone amplifier, or 8.5 hours with the FM tuner running. BASS+3D Sound Effects Two selectable sound modes add bass boost, or bass boost plus 3D surround, on top of the base tuning. Buyer's GuideWho It's For The FM Radio Listener: wants a dedicated, pocket-sized radio with real manual tuning rather than a phone app. The Minimalist Commuter: wants one small device that covers both FM radio and basic USB headphone amplification. The Retro Design Fan: likes FiiO's aluminum, dial-driven Retro Products aesthetic in a genuinely functional everyday-carry radio. How It ComparesThe RR11 is the entry point into FiiO's retro radio lineup, sitting below the RR13, which adds a built-in speaker and a replaceable battery alongside its own FM tuner and headphone amp. The RR11 keeps things simpler and smaller, at 46 grams, without a built-in speaker, making it the more pocketable option for anyone who plans to always listen through headphones.
