FiiO Tiny B Black Hi-Fi DAC & ADC Interface

Portable USB DAC Headphone Amplifier with Hi-Res Audio

The FiiO SNOWSKY Tiny B Black is a pocket-sized USB DAC and headphone amplifier designed to replace the weak built-in audio output of phones, laptops, and gaming consoles. Inside its CNC-machined all-metal T-shaped body sits a SpaceTouch SPV4040 DAC chip with an integrated audiophile-grade DSP engine, decoding PCM up to 32-bit/384 kHz and DSD256. At just 10 g and 35 × 24 × 10.8 mm, this dongle disappears in a pocket yet delivers a clean, detailed signal that surpasses typical onboard audio. Officially Hi-Res Audio certified, the Tiny B Black gives listeners a tangible upgrade over stock headphone outputs at an entry-level price.

What Sets the Tiny B Apart

Two features make this dongle stand out in the entry-level USB DAC category. The simultaneous dual-output design lets a 3.5 mm single-ended jack and a 4.4 mm headphone jack play the same audio at the same time, so two listeners can share one source with their own preferred headphones or IEMs. The 10-band parametric PEQ goes well beyond the simple bass/treble sliders found on most dongles — users dial in frequency, gain, and Q-value for each band through the FiiO Control App or web interface, then save and share presets via the cloud server.

Technical Specifications — Decoding, Power, and Compatibility

Decoding capability and output power define how well a portable DAC drives real-world headphones. The Tiny B Black supports high-resolution audio up to PCM 32-bit/384 kHz and DSD256, while the 3.5 mm output delivers 68 mW at 16 Ω with an output impedance below 1 Ω for clean signal transfer. An RGB LED indicator changes color with the active sampling rate — light blue for PCM ≤48 kHz, yellow for PCM >48 kHz, and green for DSD — giving instant visual confirmation of source quality.

Who the Tiny B Black Is For

This dongle is the right choice for listeners who want Hi-Res audio from a phone, tablet, laptop, or gaming console without carrying a full-size DAC/amp. Casual music fans will appreciate the simultaneous dual-output for sharing movies or music with a partner, each using their own headphones. Mobile gamers on Nintendo Switch or PS5 benefit from UAC1.0 mode, which delivers cleaner game audio and supports inline headset microphones for voice chat. Audiophiles on a budget get a 10-band parametric EQ to fine-tune their signature, while commuters and travelers value the 10 g all-metal body that slips into any pocket or bag.
