Powerful, power-saving CPU with 4 x Cortex-A9
The FiiO X7 utilizes Rockchip's RK3188 SoC, with 4 Cortex-A9 cores (each 35%faster than an A7) running at 1.4GHz. It is also 30% and 40% faster than Tegra3 at CPU and GPU performance respectively. The RK3188 is also made in a new 28nm process, 55% faster and 60% more power efficient than the 45nm LPSoC process, ensuring long runtime with ultra-low leakage current.
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 ES9018S in portable audio. Its 8 output channels can be bridget 4-a-side for an astonishing 135dB S/N ratio and dynamic range, while THD is as low as -120dB. Compared to the ES9018K2M popularly used in portable devices, the original ES9018S features 6dB higher SNR and dynbamic 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 os 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.
Reasonably sized for one-handed operation
The X7 utilizes a full multi-touch screen for operation. Obviously, when it comes to music players, larger is not always better. After extensive comparison with other music players, FiiO settled on a width of 64mm, which is a comfortable middle size between 58.6mm (iPhone5) and 67mm (iPhone6) that is very suitable for one-handed operation.
Given the unavoidable thickness of the X7 from having a flagship class DAC, amp and a battery to match, making the X7 comfortably handholdable from a thickness point of view is also a significant challenge. The X7 is carefully bevelled at the edges and also has a stepped design at the back, which has proven to be a comfortable hold in user testing.
Symmetrical button design. Customizable mapping for left/right handed control
We each have our handedness preference for pressing buttons on the side of the player; the X7 carries 6 hard buttons, 3 on each side in symmetrical layout: volume+/-, prev/next track, power, play/pause; all of which may be mapped to either the left or the right side for your most comfortable control.
Precision machining tolerances for reliable connections.
To ensure that the headphone amp module is easily mounted and removed, with reliable connections, precision machining is essential; the chassis is CNCed in difficult side-on manner requiring precise assembly and each part is examined via magnified projection before being accepted for use. the expansion module is secured via stainless steel star screws, which may be unscrewed using the provided tool. Hardened bronze screw nuts are installed whithin the chassis for reliable multiple installation and reinstallation of modules without fear of loosening connections.
All-purpose player - Universal decoder
Not only does the X7 suppport 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 controls are available at your fingertips in a few screens.
Intuitive and Powerful
Designed for the advanced audiophile. Swipe from left edge of the screen to show the Now Playing playlist; slide up and down on the right side of the screen to adjust volume; the X7 also has other features such as custom playlist and batch addition of deletion of favorites songs.
More fun with accessories for X7
the X7 supports pairing with Bluetooth devices for effortless wireless music playback and remote control, 3rd party apps may be also used to connect to unlimited online music via WiFi. Through firmware updates, playback via LNA, NAS and cloud storage will also be supported by the FiiO Music app.
Docking expansion functionality
Coming home from a day enjoying Hi-Fi music from the X7 on the move, you may plug the FiiO X7 onto the FiiO-exclusive docking amplifier K5 for even higher-grade home listening! The K5 charges the X7 while providing extra functionality such as ≥1.5W output power, balanced line out, and aux line in, while the X7 may continue to be connected to the computer via the K5, for e.g. USB DAC function.
