Styled in black, the FiiO X3 Mark III is a high-resolution portable audio player with a host of ancillary functions and features. For instance, it can double as an asynchronous USB DAC capable of handling 192 kHz/24-bit PCM files. The player is also Bluetooth 4.1 enabled, though not at the expense of fidelity. Three separate PCBs have been utilised in the construction of this mobile player: one for the digital section, one for analogue amplification, and another for Bluetooth.

The X3 Mark III provides both 3.5mm and 2.5mm jacks. The 2.5mm jack is for use with balanced headphones and can offer you a more detailed listening experience with a wider soundstage. The 3.5mm output, on the other hand, is not just a headphone output. It's also a line output and a coaxial jack that outputs DOP and D2P files. This means you can play both DSD and PCM files without an encoder.

Key Features

Balanced Output for a Wider Soundstage
The X3 Mark III gives you the usual 3.5mm single-ended headphone output. However, there's also a balanced 2.5mm jack that allows you to achieve a more detailed listening experience with a broader soundstage.

Dual DAC Chips
The X3 Mark III provides two high-performance PCM5242 DAC chips. These DAC chips offer a high signal-to-noise ratio, as well as effective noise reduction.

Independent, Separated Chips for a Higher-Res Experience
In the X3 Mark III, the DAC, low-pass filter, and op-amplifier all utilise separate chips to reduce the potential for interference between processes. Such interference could result in an inferior listening experience, which is why FiiO opted for this construction. Three PCBs have been employed, one for digital processing, one for analogue amplification, and yet another for Bluetooth operation.

Single-Button Construction
The X3 Mark III gives you a multi-function button, which in one press allows you to access playback controls, change the equaliser settings, or switch between playlists.

Certified Hi-Res Sound
The X3 Mark III has been certified by the Japan Audio Society as a Hi-Res Audio product.

All the Codecs You Can Handle
WAV, APE, WMA, FLAC, ALAC, MP3, and more—they're all supported, lossless and lossy alike.

Bluetooth Enabled
Bluetooth 4.1 is provided thanks to the X3 Mark III's F1C81 chipset, which enables low-latency transmission.

Accepts up to 256GB microSD Cards
With support for microSD cards up to 256GB, you can carry thousands of songs with you on the move. For instance, you can carry up to 8,000 30MB FLAC files at one time.

Multifunction 3.5mm Output
The X3 Mark III's line output doubles as a coaxial output for digital sources and is capable of outputting both D2P and DOP, so you can play both DSD and PCM files without an encoder.
