The X7 Portable High-Resolution Audio Player from FiiO is a titanium-colored, Android-based smart device that supports lossless and lossy audio files, including WAV, FLAC, APE, ALAC, WMA, MP3, and OGG. It also supports higher formats such as DXD, DSD (up to 5.6 MHz), and PCM files at up to 64-bit/384 kHz.
Beneath its aluminum chassis, the X7 houses an audiophile-grade architecture that includes the dynamic Rockchip RK3188, which helps ensure faster performance and long runtime with low current leakage. It's equipped with a ESS ES90185 DAC chip, which is designed to produce enhanced SNR and dynamic range. In addition to this architecture, the X7 is also highly customizable. It features a removable amp module that can be swapped for different input and audio characteristic options, enabling you to customize your sound experience.
The X7 is equipped with both Bluetooth and Wi-Fi technology and supports pairing with other compatible devices for hassle-free wireless playback. Additionally, the X7 offers a standard 3.5mm headphone/line-out port and a separate coaxial 3.5mm digital output port. It comes equipped with 32GB of internal storage (27GB available for music), 1GB of RAM, and features a microSD card slot that supports microSDXC cards up to 128GB for additional storage. The X7's internal 3500mAh li-polymer battery provides up to 9 hours of playback under normal conditions.
Fast, Powerful, and Efficient CPU
The X7 utilizes Rockchip's RK3188 system on chip, which incorporates a Cortex-A9 quad-core processor running at 1.4GHz, meaning you get fast, power-efficient performance with low-leakage current.
DAC for Enhanced Audio
The X7 is one of the first portable audio devices to utilize the original ESS ES9018S. Its 8 output channels can be bridged 4-a-side to produce a 135 dB S/N ratio and dynamic range, with THD as low as -210 dB.
Symmetrical Button Design with Customizable Mapping
The X7 is equipped with 6 hard buttons, 3 on each side in a symmetrical layout. The buttons can be mapped for either left- or right-handed dominance, whichever suits you best.
Intuitive and Powerful
Designed with the "advanced audiophile" in mind, the X7 is nonetheless intuitive and features a UX design anyone can grasp and enjoy. Swipe from the left edge of the screen to show the "Now Playing" playlist; slide up and down on the right side of the screen to adjust the volume; customized playlist, batch additions, and other user-friendly functions are also available.
Bluetooth and Wi-Fi Support
The X7 is equipped with Bluetooth technology for pairing with other Bluetooth-compatible devices and supports wireless playback and remote control. Built-in Wi-Fi enables you to play music from online sources using the FiiO Music app or other 3rd party applications.
Increase the X7's functionality by pairing it with the FiiO-exclusive K5 docking amplifier (sold separately). The K5 charges the X7 while it's docked and provides extra functionality, including a balanced line out, AUX line in, and more.
