Headphone Amplifier FiiO Tiny B with DAC — 3.5mm and 4.4mm Outputs, Black

The FiiO Tiny B headphone amplifier with integrated DAC is a compact black device that enhances headphone audio from compatible digital sources. It combines a digital-to-analog converter and a headphone amplifier in a small enclosure, offering both 3.5 mm and 4.4 mm outputs to support a wide range of headphones and earphones. The unit is intended for desktop and mobile listening where clearer detail, improved dynamics, and lower noise are desired compared with direct source output.

Advantages

The Tiny B provides a dedicated DAC stage to remove reliance on a source's internal conversion and reduce digital noise, while the built-in amplifier delivers sufficient output for many sensitive and mid-impedance headphones. Dual outputs (3.5 mm and 4.4 mm) allow compatibility with standard single-ended headphones and balanced-capable models using a compatible cable. Its compact footprint and straightforward control layout make it suitable for easy placement on a desk or in a bag for portable use.

Suitable for

• Improving audio detail and clarity from smartphones, tablets, and computers with digital outputs
• Driving sensitive or moderately efficient headphones and earphones
• Portable desktop use where space is limited
• Listening sessions requiring both single-ended and balanced output options

Key specifications

• Integrated digital-to-analog converter for external audio source decoding
• Headphone outputs: 3.5 mm single-ended and 4.4 mm balanced-style output
• Compact, portable black enclosure suitable for desktop or mobile use
• Controls for volume and source selection designed for simple operation

How to use

Connect the Tiny B to a compatible digital source via the designated input, then attach headphones to either the 3.5 mm or 4.4 mm jack depending on your cable and headphone type. Power the unit as required by the source or its own power method, adjust the volume control to a safe listening level, and select the appropriate output. For initial setup, start at a low volume and increase gradually while playing familiar tracks to set a comfortable listening level and verify correct channel balance.

Usage recommendations

Use the 4.4 mm output with cables and headphones designed for balanced connections to take advantage of potential noise rejection and channel separation. For mobile use, store the amplifier in a protective pocket or case to avoid contact damage, and avoid pushing the output to maximum levels for prolonged periods to reduce the risk of headphone distortion or driver stress.
