Ultra-thin aluminium alloy design - Retro yet modern The RR11 features a super-slim body of 13mm thickness with dimensions of just 83.2mm x 39.4mm x 13mm, similar to a lighter. The knob is made of aluminium alloy, truly blending retro and modern. This affordable, pocket-sized radio is for those who resonate with sound waves. Analogue PVR tuning - Feel connected to the radio Relive the magic of the good old days with a scroll wheel designed to simulate PVR tuning. Lock onto every radio frequency with just a flick of your fingers. Being able to feel the act of physically tuning to the station you want comes with the tactile feedback that digital tuners simply can't match. *The number of available stations depends on the channels available and their signal quality, and may vary in different geographical locations. Speciality radio chip - Clear and stable reception The speciality Silicon Labs Si4831 FM radio chip allows for clearer and more stable reception, as well as being able to receive a wider range of stations. Whether it's the early morning news broadcast or the late night music program, the RR11 captures the pulse of the city's sounds. Built-in antenna The RR11 is not only able to utilise headphones as an antenna but also features a built-in high-performance PCB signal gain antenna, which significantly enhances its radio reception abilities. While the RR11 is compact, its clever antenna ensures signal reception is not compromised. Ultra-wide FM band coverage - Enjoy a variety of broadcasts The RR11 supports FM frequencies between 64-108MHz, allowing it to be capable of receiving FM signals broadcast anywhere in the world as well as FM broadcasts by colleges and universities. Enjoy mainstream music stations, news programs, campus speciality broadcasts, and more – whatever you want to listen to. Specially designed circuit - Truly HiFi radio Thanks to FIIO’s nearly 18 years of extensive audio research and development experience, the RR11 is equipped with a carefully designed HiFi-grade circuit for high-quality sound. BASS+3D sound effects Immersive listening Within the RR11 is a custom DDB analogue sound effect and amplification chip capable of reproducing a classic sound as well as 3D sound effects for even more immersive listening. Battery/power outlet dual power supply A 300mAh lithium battery allows the RR11 to continuously run for over 8.5 hours. It can also be used while charging. The dual power supply modes make your experience more flexible. Enjoy music and radio broadcasts anytime, anywhere - whether during commuting, outdoor activities, or when just relaxing. *In AMP mode, the battery life runs for over 17.5 hours. It’s a radio - But it’s also an amp Included are retro-style earbuds and a digital-to-analogue cable. When paired with the analogue headphone amplifier adapter cable, the RR11 instantly transforms into a dongle-style headphone amp system. Using it this way not only increases output power but also utilises the sound effects on the DDB analogue sound effect chip to listen to music or tune into online radio stations, allowing for a charming, unique sound. Clear indicators - Lighting up every listening session The thoughtfully designed orange-yellow retro lighting effects clearly indicate important information, such as whether in stereo, tuning, and battery status. Whether you're listening to the news in the morning or to music before bed, you can easily understand the radio’s current status.
