FiiO FT13: closed over-ear with audiophile fine dynamics

With the FT13, FiiO presents a closed over-ear headphone with high technical and sonic ambitions. At the heart of the headphones are large 60 mm drivers, whose PU/wool nano wood fiber membrane promises particularly precise impulse reproduction and natural damping. The tuning is based on a slightly V-shaped signature that emphasizes fine details in the high frequencies without compromising the tonal balance. The bass remains fast and controlled, while the spatiality is surprisingly generous for a closed system.

FiiO also shows attention to detail when it comes to the features: two different ear pads made of suede and velour allowfor customization of isolation and tonality. The modular premium cable set with 3.5 mm, 4.4 mm connection and XLR adapter offers unusually flexible connectivity right out of the box. Mechanically, the FT13 impresses with its robust construction, elegant finish and a feel that clearly positions it in the premium class.

The FiiO FT13 is available for 329 euros.

Key features of the FT13

  • 60 mm dynamic driver with PU/wool/nano wood fiber cone
  • Closed over-ear design with high insulation
  • Two pad options for sound and comfort tuning
  • Modular premium cable set including symmetrical options
  • High detail resolution and precise impulse reproduction
  • High-quality mechanics and extensive accessories

FiiO K13 R2R: true 24-bit R-2-R DAC in a compact desktop format

Alongside the new headphones, FiiO presents the K13 R2R, a fully balanced desktop DAC that makes the characterful sound aesthetics of discrete R-2-R architectures affordable. The 24-bit resistor array topology delivers extremely organic, analog playback with minimal digital coloration and a particularly quiet background – ideal for long, fatigue-free listening sessions.

The K13 R2R offers versatile connectivity options including USB, coaxial and optical inputs, balanced outputs for preamps or powered speakers and a powerful headphone output. Features such as NOS/OS operation, a 10-band PEQ, LDAC Bluetooth 5.4 and a dual power supply underline its claim to be a fully-fledged audiophile center for desktop setups.

This makes the K13 R2R equally suitable as a high-quality USB source for headphones, as a preamp for compact hi-fi systems or as a flexible switching point in the modern, digital listening room.

The FiiO K13 R2R is available for 319 euros in black or silver.

Key features of the K13 R2R

  • True fully balanced 24-bit R-2-R resistor array DAC
  • Switchable NOS/OS operating modes
  • Balanced line outs and powerful headphone amplifier
  • Bluetooth 5.4 with LDAC
  • 10-band PEQ and extensive DSP functions
  • Dual power supply and low-jitter design in a robust housing

Perfect duo for audiophile chains

For demanding users, the combination of FT13 and K13 R2R forms a compact, high-resolution yet musical desktop setup. While the FT13 impresses with controlled dynamics and precise fine detail, the K13 R2R ensures organic reproduction without digital harshness. Together, both products are aimed at listeners looking for audiophile sound quality without excessive complexity.

FiiO K13 R2R: Continuation of a success story

FiiO recently caused a worldwide sensation with the K11 R2R. The model brought professional R2R DAC technology to an affordable price segment for the first time, opening up access to the characterful sound world of discrete resistor arrays for many music lovers. The new K13 R2R now takes this concept further – with more power, more options and a further refined architecture.
