Headphone Amplifier FiiO Tiny B with DAC — Gold — 3.5 mm and 4.4 mm outputs

FiiO Tiny B is a compact headphone amplifier with an integrated digital-to-analog converter (DAC) finished in gold. It combines a portable form factor with both an unbalanced 3.5 mm and a balanced 4.4 mm output, allowing connection of a wide range of headphones. The unit is designed to improve audio clarity and provide controlled headphone amplification for desktop or mobile digital sources, suitable for critical listening and everyday use.

Advantages

The Tiny B integrates a DAC and amplifier in a small enclosure to reduce signal chain complexity while delivering cleaner sound and improved dynamic control compared with typical headphone jacks. Dual outputs allow compatibility with both standard single-ended and modern balanced headphone connections, and the gold finish offers a durable, corrosion-resistant surface. Its compact size and low-profile design make it easy to place on a desk or carry with portable audio setups.

Suitable for

• Desktop and laptop users seeking improved headphone sound
• Portable audio setups where a small DAC/amplifier is required
• Users with both single-ended 3.5 mm and balanced 4.4 mm headphones
• Critical listening sessions that require cleaner signal and better control

Key specifications

• Integrated digital-to-analog converter and headphone amplifier
• Unbalanced 3.5 mm output and balanced 4.4 mm output
• Compact, low-profile metal enclosure with gold finish
• Designed for use with digital audio sources (USB/streaming devices when paired appropriately)
• Suitable for a wide range of headphone impedances and sensitivities

How to use

Connect the Tiny B to a compatible digital source following the source’s output method (for example via USB audio interface or a digital streamer using the appropriate connecting cable or adapter). Plug headphones into either the 3.5 mm unbalanced or the 4.4 mm balanced output depending on the headphone connector. Adjust the host device output level and the Tiny B’s volume control, if present, to reach a comfortable listening level without distortion. For desktop setups, position the unit on a stable surface to avoid cable strain.

Usage recommendations

Use the balanced 4.4 mm output when available for improved channel separation and lower crosstalk with compatible headphones. Start with moderate volume levels and increase gradually to protect hearing and to allow the amplifier and headphones to settle. Keep the unit in a well-ventilated area and avoid exposure to liquids or extreme temperatures.
