FiiO Portable FM Radio & Headphone Amplifier | Custom FlIO DDBAS100 Chip

Experience classic FM radio broadcasting and ultra-clean analog amplification with this compact dual-mode portable player. Designed for audiophiles on the move, it functions both as a sensitive multi-band FM receiver and a dedicated high-performance portable headphone amplifier.

Key Highlights

• Pure Analog & Radio Experience: Pure wired analog amplification paired with an advanced FM receiver for distortion-free, low-latency listening (no Bluetooth latency or compression).

• Dual-Band FM Tuner: Powered by the Si4831 reception chip, offering wide-frequency coverage across standard and extended bands (FM1: 87–108MHz / FM2: 76–90MHz).

• Custom Acoustic Tuning: Integrated with the custom FlIO DDBAS100 analog sound effect chip for dynamic audio output and warm sound signature.

• Dedicated High-Power Headphone Amp: Delivers up to 80mW + 80mW @ 32Ω with an ultra-low output impedance (<1Ω), perfect for driving everything from sensitive IEMs to full-sized gear (8–1000Ω).

• Long Battery Life: Outstanding efficiency delivering up to 18 hours of continuous play in Headphone Amplifier mode via Type-C fast charging.

• Dual Output Options: Seamlessly switch between private headphone sessions and shared listening via built-in stereo speakers.

Product Description

Pure Analog Sound & Zero-Compression Radio

Engineered for users who demand uncompromised analog clarity, this device acts as a dual-purpose audio Companion. In Headphone Amplifier Mode, it bypassing wireless compression to deliver a ultra-clean signal path with an SNR of >100dB, THD+N as low as <0.008%, and background noise floor under 10uV.

High Sensitivity FM Receiver

Equipped with the Si4831 receiver chip, tune into high-fidelity local broadcasts across both international and regional Japanese FM bands (76–108MHz combined range).

Pocket-Sized & Lightweight

Crafted into an ultra-compact body measuring just 43.4 x 85.6 x 16.4 mm and weighing approximately 76g, making it ideal for daily pocket carry or travel setups.

Sleek Aesthetic Finishes

Choose between four distinct metallic finishes—Black, Silver, Retro Gold, and Red.
