Q7: The Portable Desktop-Class Headphone Amplifier
Audiophiles and audio enthusiasts looking for a portable amplifier with the power of a desktop unit should look no further than the FiiO Q7 Portable Desktop-Class Headphone Amplifier, a true fusion of quality desktop components packed into a portable enclosure. The Q7 redefines what a portable amp can be and sets a new benchmark not only for FiiO portable products, but for all portable products.
Powerful Features
The Q7 features a switchable power system which provides 3000mW of power for its enhanced over-ear headphone mode, while the portable mode outputs 1500mW. Originally designed for desktop usage, the THX AAA 788+ amplifier features a 4-way true balanced amplifier circuit with five levels of mixed gain, which effortlessly powers all kinds of headphones for a pure listening experience. The Q7 ships with a leatherette case, cooling stand, USB power cable, power adapter, AC power cord, USB adapter, two USB-C to USB-C data cables (long/short), and a lightening cable.
Desktop-Level Connectivity
The Q7 is equipped to handle any situation with USB, optical, and coaxial inputs, and has two single-ended headphone outputs (1/4"/3.5mm) and two balanced headphone outputs (4.4/2.5mm), plus a line output too.
Desktop-Caliber Power Supply
  • The Q7 can be operated in either DC or battery-powered modes. Under the battery-powered mode, the 9200mAH battery is up to the task of powering the Q7 output up to 1500mW of power. Under DC-power-supply mode, the battery is bypassed to protect the battery's life, while the custom 24W low-noise power supply effortlessly drives a wide variety of headphones with aplomb.
  • The five-stage audio circuit features 20 LDOs and a 470mF high-capacity, ultralow ESR supercapacitor in order to provide endless reserves of power in order to maintain stable high-quality audio at all times.
Desktop-Grade Decoding
  • 16-Core XMOS XU316: Dual audio clocks, ultralow latency, 768 kHz, DSD512, and MQA full decoding
  • High-end DAC ES9038PRO: Four channels connected in parallel for one differential output provides excellent resolution
  • Qualcomm QCC5124: Bluetooth receiver with support for hi-res Bluetooth formats like LDAC, and APTX Adaptive, aptX LL, and aptx HD
FiiO Digital Control Core
FiiO upgraded their self-developed digital control core center, which utilizes a control chip powered by an ARM Cortex M4 processor that efficiently handles tasks such as clock management, USB decoding, and optical decoding, to optimize sound quality. To further enhance sound quality, the digital and analog sections are physically separated on different boards with shield covers to achieve an extremely pure sound, for a superb listening experience.
LED Indicators
The Q7 continues FiiO's modern design language, featuring a bold next-generation mech design complemented by tasteful color lights for a thoroughly technologically modern appearance.

  • Blue: ≤48 kHz, Yellow: >48 kHz, Green: DSD, Pink: MQA
Full-Color High-Definition Display
