FiiO X7 Mark II High-Resolution Lossless Portable Music Player

Designed for audio enthusiasts, the FiiO X7 Mark-II is a portable high-resolution audio player which seeks to take fundamental concepts put forth in the original X7 and expound upon them. The player features premium components capable of playing files up to 32-bit / 384 kHz in a variety of formats including native DSD, DXD, WAV, WMA, ALAC, FLAC, APE, AIFF, and more, utilizing a redesigned internal architecture to offer more protection against electromagnetic interference than its predecessor. This is especially important, considering the unit’s extensive support of Wi-Fi (in both 2.4 and 5 GHz bands) and Bluetooth (with 4.1 and aptX offered).


The X7 Mark-II utilizes an 8-channel ESS ES9028PRO DAC coupled with three crystal oscillators and topped with an included amplifier module sporting custom-designed op-amps; all of this means a significant improvement in jitter-reduction, soundstage preservation, and other aspects of conversion over its predecessor, the X7—a unit that was nothing to sneeze at in the first place.

The device provides a 3.5mm headphone output and a separate 3.5mm connector that can output analog (line-out) or digital signals (coaxial and optical). The FiiO also has a 2.5mm balanced TRRS headphone output.

2GB of RAM is on-hand for handling multiple tasks at once, while 64GB of internal storage can be augmented with micro-SD cards to give you up to 576GB of storage. For a more extensive list of this item’s capabilities, please peruse the features section.
