FiiO X7 Audiophile Digital Audio Player




Technical specifications

No-compromises DAC for the Ultimate Sound

Designed originally for hi-end home audio, the X7 is one of the first devices to utilize the original ESS E89018S in portable audio. Its 8 output channels can be bridged 4-a-side for an astonishing 135d8 S/N ratio and dynamic range, while THD is as low as ~120dB. Compared to the ES9018K2M popularly used in portable devices, the original E39018S features 6dB higher SNR and dynamic range at the cost of higher power consumption, a cost that the X7 is willing to pay with its robust power section.


Patented source + amp design for best of both worlds

Patent-pending dedicated source module + independent headphone
amp module design keeps the compact integrated profile of a single
portable music player while providing the sonic advantages of utilizing
a separate headphone amplifier. The resulting customizability allows
you to customize the resulting sound (warm, neutral, etc), output power
(for driving IEMs or full-size headphones) or output port (single-ended
or balanced, etc.) by choosing among different modules.


All-purpose player-universal decoder

Not only does the X7 support popular lossless / lossy music formats such as WAV, FLAC, APE, ALAC, AIFF, WMA, MP3, OGG, etc , higher formats such as DXD, DSD64/128 and PCM are supported at up to 384kHz/64bit | 5.6MHz (DSD).

X7's own customized music app

X7’s embedded music app (FiiO Music ) was researched and developed with almost as much effort as the hardware itself. Compared to usual Android music player apps, the X7 music app handles lossless music more proficiently and is more user-friendly. The UI is clear and concise, and all status indicators and control's are available at your fingertips in a few screens.
