  • The X5II 2nd Generation from FiiO is a portable high-resolution audio player and USB DAC for audio enthusiasts. The unit features an audiophile-grade architecture and premium components capable of playing files up to 24-bit/192 kHz in a variety of formats including native DSD, WAV, WMA, ALAC, FLAC, APE, AIFF, and more.

    The X5II utilizes a Texas Instruments PCM1792A DAC coupled to an OPA1652 for great dynamic performance, while the FET inputs for I/V conversion offer extra-low distortion and noise. Additionally, two top-flight OPA1612 chips provide low pass filtering and voltage amplification for extra-low distortion and noise. The headphone output employs two BUF634U chips for current buffering, resulting in a sufficient drive current for a wide sound stage, high dynamics, and good bass power. Dual crystal oscillators ensure the lowest jitter and highest precision playback of music at any sample rate, eliminating conversion artifacts.

    The X5II offers a standard 1/8" / 3.5mm headphone output and a separate line out/digital (coaxial) out via 1/8" / 3.5mm. The X5II has no on-board memory, but uses two microSD card slots supporting up to 256GB total. The 3300mAh Li-polymer battery provides up to 10 hours of playback under normal conditions. The user interface offers five unique themes, while the classic scroll wheel and 2.4" HD IPS color display offers easy navigation. You can browse and play songs via folders, songs, albums, artists, genres, favorites, and playlists. The 10-band graphic EQ and the 120-step digital volume control allow for custom-tailored sound and levels.

    The X5II is 15% lighter and 12% smaller than the original X5. The chassis is made of aluminum alloy and features a high-reflectance, fine-grain faceplate. The X5II ships with a 3' / 1m high-current Micro-USB data/charging cable, an 1/8" / 3.5mm coaxial S/PDIF adapter, a black silicone case, three screen protectors (1 applied in-factory), an HDtracks coupon, and a set of three Bodywork stickers (USA flag, wood grain, and carbon fiber).
