{"type":"firestarter.listing","listing":{"id":"lst_mTDJRWiC","product_name":"FiiO RR11 Stereo Radio","category":"Radios","description":"Wide-Band Analog Tuning Radio\nThe RR11 is a pocket-sized stereo FM radio designed for daily carry. Its ultra-thin aluminum body, wide-band FM tuning, dual power modes, retro lighting, and specialty audio circuitry make it a compact companion for listening at home, outdoors, or during commutes. It also doubles as a portable headphone amp with the included dongle, giving you more ways to enjoy music.\nUltra-thin aluminum body\nThe 13mm-thick aluminum housing slips easily into a pocket, keeping the RR11 ready whenever you want to tune in. Its compact dimensions — 3.27in x 1.55in x 0.51in (83.2mm x 39.4mm x 13mm) — give you a light, durable device you can take anywhere.\nAnalog PVR tuning\nThe analog tuning wheel lets you scroll across the dial with tactile precision. Each adjustment gives you controlled, hands-on tuning across multiple FM bands. It also brings back the physicality of radio listening, making it easy to lock onto the station you want.\nSpecialty FM radio chip\nThe Silicon Labs Si4831 chip is engineered for clean, stable FM reception. It picks up a wide range of stations with less noise, giving you reliable listening whether you're catching morning news, music programs, or community broadcasts.\nUltra-wide FM band coverage\nThe RR11 supports FM frequencies from 64MHz to 108MHz. This includes campus radio, Japanese FM, and global standard FM broadcasting. You can move between FM3 (64–87MHz), FM2 (76–90MHz), and FM1 (87–108MHz) using the slide switch.\nBASS+3D sound effects\nThe custom DDB analog sound-effect and amplification chip gives you two distinct voicings — a classic balanced tone or an expanded 3D mode for more immersion. These effects apply both to FM listening and when using the RR11 as a headphone amp.\nSpecially designed circuit\nFIIO’s audio engineering experience informs the HiFi-grade circuit inside the RR11. It reduces distortion and preserves signal clarity, whether you’re listening through the radio tuner or the amplifier mode.\nDual FM/AMP modes\nYou ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-silver-1209631497.jpg?v=1764634977","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-1217697353.jpg?v=1769019549","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-1220902916.jpg?v=1771014007","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-1220902915.jpg?v=1771013948","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-silver-1209631496.jpg?v=1771003882","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-silver-1209631499.jpg?v=1771003882","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-radios-fiio-rr11-stereo-radio-silver-1209631498.jpg?v=1771003882"],"price":47.99,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.804Z"},"share_url":"https://firestarter.network/l/lst_mTDJRWiC","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
