Product information

Description

The FiiO K7 BT is a compact desktop audio DAC-amplifier designed to drive headphones and provide a clean line‑level output for near‑desk and home audio setups. It combines a digital-to-analog converter with an integrated headphone amplifier and Bluetooth connectivity to accept sources wirelessly or via wired inputs. Key measured performance parameters include very low total harmonic distortion (THD 0.0003%) and a high signal-to-noise ratio (SNR 116 dB), and the unit provides a 6.35 mm headphone/speaker output. The device is powered by a 12 V DC supply and has a solid, portable desktop footprint weighing 610 g in a black finish.

Advantages

The FiiO K7 BT offers precise audio reproduction with extremely low distortion and a high SNR, ensuring detail and low noise for critical listening. Integrated Bluetooth allows flexible wireless source connection while wired inputs provide stable, high-quality signal paths. A standard 6.35 mm output supports a wide range of headphones and active speakers. The compact, lightweight design is convenient for desktop placement without occupying much space.

Suitable for

  • Near‑desk headphone listening and desktop audio systems
  • Connecting digital sources via Bluetooth for casual or focused listening
  • Providing line‑level output to amplifiers or active speakers
  • Use in small home studios for monitoring or reference listening

Key specifications

  • Total harmonic distortion (THD): 0.0003%
  • Signal‑to‑noise ratio (SNR): 116 dB
  • Output: 6.35 mm headphone/speaker jack
  • Power supply: 12 V DC (maximum current up to 2 A)
  • Weight: 610 g
  • Colour: Black

How to use

Connect the FiiO K7 BT to a compatible 12 V DC power adapter and place it on a stable surface near your listening position. Pair a Bluetooth source following the device's pairing procedure, or connect a wired digital or analog source to the appropriate input. Plug headphones or connect active speakers to the 6.35 mm output. Adjust volume and source selection using the front‑panel controls or input selectors. Allow a short warm‑up time for the circuitry after powering on for optimal performance.

Usage recommendations

For lowest noise and best signal integrity, use high-quality interconnects for wired connections and keep the power adapter and audio cables separated from other mains or data cables. When using sensitive headphones, start with low volume settings and increase gradually. Place the unit on a non-resonant surface and ensure adequate ventilation around the chassis to avoid heat buildup.

Technical details

Bluetooth: Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
