Frequently Asked Questions - X7MKII FiiO

What is the battery life of the FiiO X7 Mark II?

The X7 Mark II uses a 3800mAh Li-poly battery and provides approximately 10 hours of playback under normal conditions. Actual battery life may vary depending on usage and settings.

How long does it take to fully charge the X7?

With a Quick Charge adapter (DC 9V/1.5A or 12V/2A), it takes about 2 hours. Using a standard DC 5V/2A adapter, it takes about 4 hours.

Can the X7 be used while charging?

Yes, the X7 is designed to be used while charging without performance degradation or safety issues. However, the battery will charge more slowly and the device may become warm, which is normal.

How do I update the firmware on the FiiO X7?

Firmware can be updated over-the-air (WiFi required) or locally by copying the update zip file to the internal storage or SD card and selecting 'Firmware Update' in the 'Technical Support' app. Ensure the battery is fully charged before updating.

Why can't my APE files play on the X7?

The X7 supports APE files with compression levels Fast, Normal, High up to 384kHz/24bit, and Extra High/Insane up to 192kHz/24bit. If your APE file is beyond these specifications, it may not play. Consider converting to FLAC or WAV.

Does the X7 support CUE sheets?

Yes, the X7 supports external CUE sheets. The .cue file must be named exactly the same as the corresponding music file and placed in the same folder. Embedded CUE sheets are not supported.

How can I connect the X7 to other audio equipment?

Use the 3.5mm multifunctional output set to Line Out (for analog) or Coaxial/Optical (for digital). For line out, connect to a line input on an amplifier or powered speakers. For digital, use the included S/PDIF adapter cable.

What is the maximum supported micro SD card capacity?

The X7 supports micro SD cards up to 256GB per slot, for a total of 512GB when using both slots. High-speed Class 10 or above cards are recommended for high-bitrate files.

How do I transfer music to the X7?

Connect the X7 to your computer via USB, then tap 'Turn on USB storage' on the X7 screen. The internal storage and SD cards will appear as removable drives. Simply drag and drop music files or folders. No driver installation is required.

Why is the X7 slow or unresponsive at times?

Slowness may occur when playing very high-bitrate files (e.g., 384kHz/24bit APE or DSD), or if the micro SD card is slow or contains many non-music files. Organizing files into folders and using Class 10 cards can improve performance.

Then connect the LINE/COAX/OPT OUT port on top of the X7 to the line in / aux in port of your equipment via an appropriate interconnect. The Line Out is a standard high level line output and is for connecng to line inputs such as that on headphone amplifiers, AV receivers, loudspeaker preamps, powered speakers, etc. The default line output level is high (2V) and can damage headphones. In any case,

headphones are not meant to be connected to a line output and will perform poorly.

Could X7 be used with FiiO's docking staon?

A: X7 could be used with FiiO's docking staon DK1 and desktop amplifier K5 via Micro USB conncon.

The X7 does not get detected by my computer for le transfers?

How to connect the X7's Coaxial/Opcal digital output to other equipment? What to connect it to?

A: First, make sure that the Mulfunconal Output is set to Coaxial or Opcal digital out. Then connect the LINE/COAX/OPT OUT port on top of the X7 to the provided S/PDIF adapter cable. Then connect the other end of the adapter cable to your equipment's Coaxial or Opcal input with an appropriate RCA coaxial cable or Opcal cable.

Note: Dierent manufacturers may have dierent pin-out denion of the coaxial cable plug. Please use the coaxial cable supplied with the X7 to avoid the no output problem resulting from incompatibility.

Why does my HT receiver never play the rst ten seconds of music from my X7?

A: If the HT receiver is not explicitly set to receive audio from the coaxial port, it takes approximately ten seconds to detect that audio is not coming in through the HDMI port and switch to the coaxial port. In this case, please set the HT receiver's audio input to Coaxial.

7. Other operaons

How to get longer baery life for the X7?

A: a) Set the display to sleep aer a certain period of inactivity (system Sengs->Display->Sleep), and lock the screen before pung the X7 in your pocket, so that the touchscreen does

not connue accepng input in your pocket and keep your X7 acve.

b) Turning down the backlight brightness and turning o the pulsar light can also save baery.
c) Go to X7's system sengs -> Powermer -> Idle powero to set the Idle powero mer; And aer the set me of inacvity, X7 will power o automacally to save power.

Why is the X7 a bit sluggish in responding at mes?

A: a) High bitrate lossless tracks, particularly 384k/24bit APEs or DSD les, take more hardware resources to decode, possibly causing slowdowns in the player UI. You may convert such APEs to FLACs or uncompressed WAVs using programs such as foobar2000 on the computer rst to make it easier on the player. The sound quality will be the same.

b) Massive songs stored in the micro SD card might also result in operaon delay.
c) Massive les of non-music formats like photos, videos stored in the Micro SD card might cost extra me on idencaon.

d) Playing high bitrate les or DSD les from slow micro SD card might cause stuering. Class 10 or above genuine micro SD cards are recommended.

e) Disordered les (such as various APE albums and CUE les all put into one folder) might slow down the loading speed. It's recommended to create folders in this method: rst create folder of dierent arsts then create subfolders of dierent albums under the arst folder.

f) Dierent formats or bit rate les stored together might increase processing me. It's recommended to create dierent folders to store dierent format les and choose playback by folders to avoid X7 switching decoder frequently.

Why does the X7 get a lile hot in operaon?

A: The X7 ulizes an SoC with high clock speed, a separate DAC, and (also separately) a high power headphone amplifier and independent analog volume control in the amplicaon stage, thus dissipang way more power than consumer DAPs typically performing computaon, DAC and amplicaon all on the SoC. Apart from outpung more power to your headphones, a lot of this power is also dissipated as heat, thus causing the X7 to heat up slightly in operaon; but this does not endanger the X7 or the listener in any way.

Why can't I go to the homescreen by pressing the home buon?

A: Please check the X7 operaon mode you are currently in by pulling down the sengs menu from the upper right of the touchscreen. If you're in Pure Music mode, tap on the mode icon to switch to Android mode, aer that you will be able to access the Android homescreen.

Note: You can pull down from the upper right of the screen twice to enable the Quick sengs menu and view the current system mode.

Why can't I see the Quick sengs menu when I pull down from the top of the touchscreen?

A: There are two levels of pull-down menus. Aer the rst pulling down, you will see the nocao panel and aer the second pulling down you will see the Quick sengs menu.

Does the X7 support 256GB micro SD cards?

A: Yes.

Does the X7 coaxial digital output support DoP? At what rate?

A: Yes. The DoP output can be supported at up to 2.8MHz/1bit (DSD64).

Why can my X7 not receive OTA updates / why is the OTA update so slow?

A: The update download may be slow owing to network constraints, at the FiiO server's end, in the intermediary network, at your Internet ISP, your WiFi router, or owing to poor WiFi reception by the X7 (move closer to the router / hotspot). In any case, you may press the Home buon to dismiss the update download progress bar and connue using the X7 normally while the update downloads. You may even switch the X7 o and on and the update download will connue.

Why somemes it shows "0 new songs added to media library" aer updang?

A: X7 has adopted the incremental update method. If the songs had already been added to library, then they wouldn't be added in the next scanning. Therefore it would show "0 song added to media library" aer the uupdate. And this is not an update failure. Because of the incremental update scheme, the player is able to support the "Newly added" funcon and also save the scanning me.
