FiiO K7 BT Bluetooth DAC & Headphone Amplifier
The FiiO K7 BT Bluetooth DAC & Headphone Amplifier holds some of the most powerful DAC & Amps, like the K9 Pro, K9 Pro ESS, and K7.
Building on its reputation FiiO takes great pleasure in introducing its all-new versatile Desktop DAC & Amp + Preamp – the K7. The FiiO K7 is a “truly” balanced headphone amplifier with THX AAA 788+ amp technology incorporated into its circuitry.

Features
Balanced amplification couldn’t sound better
Using the same THX AAA 788+ amplifiers as the K9 Pro, the FiiO K7 BT Bluetooth DAC & Headphone Amplifier is capable of outputting 560mW into a 300Ω load at 1% distortion, and 200mW into a 32Ω load at 1% distortion. This ensures both low and high impedance headphones are fully powered with optimal musicality.
Dual AK4493SEQ D/A chips
The left and right channels are each equipped with an efficient high-performance AK4493SEQ D/A chip. These 32-bit D/A chips support 768kHz PCM and DSD512, ideal for high-resolution audio source playback.
RGB indicator lights
The RGB indicator lights are capable of displaying single colors as well as mixed colors, with a unique light flow effect during power on/off or input switching.
Worry-free listening
Overheating, overload, and DC protection systems ensure that the K7 always operates at its best, so you can always enjoy a worry-free listening experience.
Multiple independent power stages
The K7 features a power design consisting of multiple independent stages, with the voltage of each stage regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply. All in all, the K7’s power design supplies plentiful, clean power for an extraordinary listening experience.
Smooth operator
The K7 features an all-aluminum alloy construction, carefully finished with CNC and other processes. Its elegant black color is perfectly complemented by the gold accents of the THX and Hi-Res Audio badges and the splashes of color from the RGB lights.
Precisely-tuned volume
Thanks to its ADC curve reconstruction, the volume potentiometer features 112 smooth steps of adjustable volume free of channel imbalances and noise.
Space-conscious design
The FiiO K7 BT Bluetooth DAC & Headphone Amplifier features a space-conscious design that only measures 2.1 inches thick and with a footprint smaller than ⅓ of an A4 sized sheet of paper–allowing it to fit snugly on even small desks.
