The FiiO M17 combines portability with desktop-level features. Weighing in at just over 600 grams, it is not pocket-sized but remains easily portable. It boasts top-tier components and a variety of functions that will make any audiophile's heart race: two ES9038PRO DAC chips, two THXAAA-788+ amplifiers, a dual power supply, a built-in 9,200 mAh battery, Bluetooth 5.0, WiFi, and a sharp, color-accurate 5.99-inch Incell touchscreen display. Thus, the M17 delivers performance and sound quality typically expected only from stationary systems, all in a portable form.

The Android-based operating system allows for the installation of any apps, enabling the use of streaming services like Tidal, Qobuz, Apple Music, Spotify, and more. For those who wish to enjoy music playback in its purest form, there is an option to turn off the Android system and listen in Pure Music Mode for an entirely authentic sound experience. The M17 can also be used as a USB DAC with a PC, providing high-quality sound on Windows or Mac computers. The two ES9038PRO DAC chips generate a highly faithful sound. The two THXAAA-788+ amplifiers ensure that any type of headphone is effortlessly driven, with gain adjustable by up to 16 dB, which corresponds to impressive power even for stationary devices.

The FiiO M17 features four headphone outputs, allowing most headphones to connect directly. Additionally, there are coaxial input and output ports, as well as two USB-C ports. Volume can be adjusted in 120 steps either via the dial on the top or the buttons on the right side of the M17. Included in the package are a power supply and a stand with an integrated fan for good air circulation during stationary use of the player.
