Compact black DAC headphone amplifier with 3.5mm and 6.35mm outputs

BFKK

BFKK DX1 DAC headphone amplifier 280mW 32bit AK4493S 384kHz DSD256 Black

SKU CH-AGNY-THQR2

Portable USB DAC and headphone amplifier with AK4493S chip decoding 32-bit/384kHz PCM and DSD256, delivering 280mW into 32 ohms and 51mW into 300 ohms via 3.5mm and 6.35mm outputs.

  • AK4493S DAC delivers 120 dB dynamic range for transparent sound
  • 280 mW into 32 Ω and 51 mW into 300 Ω drives IEMs and full-size headphones
  • Discrete LNRD reduces DAC noise below 2.0 µV and amp noise below 1.0 µV for silent backgrounds
  • Fixed-level line output lets the DX1 serve as a pure DAC alongside external amplifiers
  • Plug-and-play on Windows 10, 11, macOS, Linux, iOS and Android without extra drivers

Portable headphone DAC amplifier

The BFKK DX1 is a compact USB DAC and headphone amplifier designed for listeners who want higher-quality audio from computers, phones or tablets. It suits owners of sensitive in-ear monitors and full-size headphones who need clean power without a large desktop unit.

Dual-gain 280 mW output headroom

Two gain stages and both 6.35 mm and 3.5 mm jacks let the DX1 drive loads from low-impedance IEMs up to 300 ohm headphones. At 32 ohms it delivers 280 mW per channel, falling to 51 mW per channel at 300 ohms, so very high-impedance models may not reach desired volume.

Fixed-level line out for system integration

A fixed-volume line output allows the DX1 to serve as a pure DAC feeding external headphone amplifiers or power amplifiers. Both headphone and line outputs are active simultaneously, and the line level cannot be adjusted, so users needing variable pre-out control must look elsewhere.

Questions about this item

Will the 3.5mm and 6.35mm outputs drive both my sensitive IEMs and 300 ohm headphones without noise?

The amplifier delivers 280mW at 32 ohms and 51mW at 300 ohms with selectable high/low gain. Discrete LNRD keeps DAC noise below 2.0 uV and amp noise below 1.0 uV.

How can I verify the AK4493S is decoding 32-bit 384kHz PCM and native DSD256 correctly?

The device is driver-free on Windows 10, 11, macOS, Linux, iOS and Android; your OS audio panel will show 32-bit 384kHz capability and DSD256 support when playing test files.

Does the box include both 3.5mm and 6.35mm cables or must I buy them separately?

The unit provides built-in 3.5mm and 6.35mm headphone jacks plus a fixed-level line-out; connect your existing headphones and RCA or 3.5mm interconnects — no extra cables are required for basic use.
