Please read the following instructions for firmware updates carefully before proceeding.
To check the current firmware version:
From the main menu, navigate to System Settings->About X3 to see the current firmware version loaded on your X3.
Preparations / Precautions before firmware update:
•A micro SD card formatted in FAT32 is required for firmware updates. This may be obtained by formatting a card using the X3's built in formatting function (System settings ->Storage formatting).
CAUTION: all data and music on a card will be erased by formatting.
•A firmware update should not affect data on the micro SD card (other than any formatting required, see above). Nevertheless, please back up any important data on your card to protect against accidents.
•Make sure the X3 is adequately charged (preferably fully charged) for the update process to prevent power failure during the update;
•Do not operate other buttons and dials on the player during the update process.
•If the update process fails, hold the power button for 10 seconds for a forced shutdown and turn the player on in update mode again to resume the update.
Summary of procedure for upgrading firmware using micro SD card:

CAUTION: all data and music on a card will be erased by formatting.
There is no need to update each firmware, and please just load the latest firmware and upgrade the X3 directly.
F. Tips on usage
This section contains some useful tips for you to get the most out of your X3.
How to update the media library quickly?
A: It is recommended to set System Settings->Update Media Lib to Auto, so that the X3 will update the media library automatically each time after you connect it to the PC or insert/remove a micro
How to play your favorite songs quickly?
A: When in the Category sub-menus or when browsing files, hold the Shortcuts key to search by the first letter of the song/file to quickly jump to the song you want to hear. Go to the Favorites menu to add a batch of your favorite songs (or favorite individual songs as they are played in the Now
Playing screen) and then enter the favorites menu to enjoy all your favorite songs. The X3 supports addition and removal of songs defined in .cue files to favorites as well for your enjoyment of lossless rips of CDs/DVDs/etc.
How to cut over to the song you want to listen to and adjust volume quickly?
A: Turn the scroll wheel in the Now Playing screen to pop up a list of songs before and after the current playing song. Turn the scroll wheel to choose between songs, press OK to select and start playing the new song.
Hold the Play button and Volume adjustment dialogue pops up, then use the wheel to adjust volume.
4. If you have something to attend to while listening, how do you leave the X3 on while saving power, so that you can later continue listening where you left off?
A: If you are listening to music as you fall asleep at night, you can set a sleep timer so that the X3 automatically enters deep sleep after a certain amount of time of playing music and not being operated. (Note: The sleep timer is reset and turned off after being triggered once.)
If something suddenly comes up and you cannot listen to music, by default the Idle Standby option is turned on so that after a set amount of time, music playback stops, which saves battery power.
G. Frequently Asked Questions
1. About charging
Q: What power sources may be used to charge the X3?
A: The X3 may be charged by any USB charger with 5V output voltage like computer, power bank, and adapter. It's recommended to use the 5V/2A charger.
Q: What is the charging current of the X3 while charging?
A: Less than 500mA through a computer USB port or approximate 1.3A through a dedicated USB charger as recommended (DC 5V 2A).
Q: How long does it take to charge up the X3?
A: A full charge through a dedicated USB charger as recommended (DC 5V, 2A) takes about 3 hours.
Q: Can the X3 be charged by a power bank?
A: Yes, as long as the current is higher than 1A.
Q: Can the X3 play songs while charging?
A: Yes; no harm will come to the X3 if you use it while charging, in which case it is normal for the X3 to get warm. The reason we recommend turning the X3 off for charging is so that charging completes more quickly.
Q: What to do if the X3 gets a little hot when playing songs while charging?
A: It is normal for the X3 to get a bit hot in these conditions and this does not endanger the X3 or the listener in any way. If you are worried about this, it is better to take off any casing to expose the
X3 to air for cooling down. If you're still worried, turn down the volume on the X3 or turn off the player for charging.
Q: Can the X3 be connected to chargers via other micro USB cables?
A: Yes, but the micro USB cable that comes with the X3 is specially constructed with thick power line conductors to minimize power loss while charging. Using other micro USB cables may lead to slower charging; very poor quality USB cables may cause so much power loss through the cable as to fail to charge the X3 altogether.
Q: Why does the X3 charge so slowly or not at all through a front USB port on a desktop computer?
A: The front USB ports on a desktop computer are connected to the motherboard through long thin
cables, which cause too much voltage drop when connected to high current draw equipment like the X3.
Q: Why does the battery capacity indication not accurate?
Because X3 will judge the battery capacity by the voltage of the battery, so it's not very accurate.
Also the battery voltage might differ while playing music. Therefore, the battery capacity indication is for reference only.
Q: How to judge the X3's charging status?
A: On the bottom of the front panel, there is a charging indicator LED, which lights up red while charging and green when fully charged. The battery level of the onscreen battery gauge (on the upper right corner while the player is on, or taking up the whole screen if the player is off) moves to indicate battery charging.
Q: How to tell whether the X3 is fully charged or not?
A: When X3 gets fully charged, the status indicator LED on the power button lights up green and the onscreen battery gauge (on the upper right corner while the player is on, or taking up the whole screen if the player is off) stops moving and holds steady at full.
2. Transferring songs
Q: What operating systems does the X3 support (for transferring songs)?
A: It supports 32bit and 64bit Windows XP, Windows 7 and above, as well as Mac OS 9, X, and most versions of Linux and Unix.
Q: What USB ports are the X3 compatible with?
A: The X3 is compatible with USB 2.0 (and all later standards that are backwards compatible with
2.0, including 3.0 and 3.1).
Q: How quickly does the X3 transfer songs?
A: This is dependent on the size of files / songs transferred and the Class of the micro SD card; average read / write speeds are about 5MB/s.
Q: Why does it transfer so slowly through a front USB port on a desktop computer?
A: The front USB ports on a desktop computer are connected to the motherboard through long thin cables, which may degrade the signal quality and hence reduce the speed of transfers; it is recommended to connect to a rear USB port on a desktop computer to transfer data.
Q: Does the X3 support deleting or copying files by dragging through the computer's File Manager?
Q: Is a driver required for connecting the X3 to computer?
A: No driver is required for connecting the X3 to a computer for file transfers.
Q: Does the X3 support Linux?
A: Theoretically it is supported (as a generic mass storage device), but we cannot guarantee support through actual testing of all the various OSes out there.
3. Firmware upgrades
Q: How to know what firmware version is on my X3 and what is the newest version?
A: The current firmware version can be viewed via System Settings->About X3. All firmware versions for the X3 may be downloaded via http://www.fiio.net/en/supports/46

Q: How to update the X3 firmware?
A: Please refer to Section E. Firmware Update in this user manual.
Q: Is it possible to brick the X3 while upgrading the firmware? What to do if my X3 is bricked?
A: It should not be possible to brick the X3 in the normal course of upgrading its firmware. If you somehow manage to brick
Q: What cards does the X3 support?
A: The X3 supports TF cards (also known as micro SD cards), including SDHC and SDXC.
Q: Is the X3 picky about cards?
A: The X3 has been tested to support major brands such as Sandisk and Kingston very well. It is beyond our ability to test every other brand out there, but any genuine card from a reputable brand should work with the X3. To prevent slow card speeds causing the X3 to stall while playing or
be unable to play high bitrate lossless tracks (such as 192k/24bit APE files or DSD files), please use micro SD cards of Class 6 or above.
Q: What size of cards does the X3 support?
A: The X3 is currently tested to support micro SD cards up to 128GB. It is recommended to format the card in FAT32 format.
Q: How to format the micro SD card into FAT32 format?
1. Simply insert the card into the micro SD card slot in the X3, go to System Settings->Storage formatting, press OK to select and OK again to confirm formatting the card to FAT32 format. or
2. Insert the micro SD card to a card reader to connect to your computer, right-click on the micro SD card shown and choose "Format…" and follow the prompts to format the card to
FAT32 format.But please do not choose 64K under the Allocation unit size when formatting the micro SD card. Also, Micro SD cards in 64G or 128G sizes cannot be formatted into FAT32 by the windows system, please try to use third party tool (such as Guiformat or smdk_fat32) to format.
Warning: all data and existing songs on the card will be deleted, please make backups on your computer first as necessary.
Q: Nothing from the micro SD card shows on the X3?
1. Play by Category will not show any songs from a card unless and until a media library update has been performed. Go to System Settings->Update Media Lib, press OK and select "Manual" to perform a manual media library update.
Or use Browse Files to confirm that the files on your card are recognized by the X3.
2. If neither of the above works to show you the songs on your card: i. Go to System Settings->About X3 and check that the Available Capacity of the micro SD card you inserted is shown correctly (comparing it to the info shown on your computer); if not, try formatting the card using the X3 (this deletes all files on the card; please back up your data and music first) and putting your files back on the card; ii. If this does not help, you may try formatting the card into NTFS format using Windows; iii. If none of the above helps, it is recommended that you try another card with the X3.
Q: Some songs on the micro SD card don't show on the X3?
1. Have you performed a media library update after you last loaded songs onto the card? Go to
System Settings->Update Media Lib, press OK and select "Manual" to perform a manual media library update.
2. If songs are still missing in "Play by category" (while they all appear in Browse files), try to reset the media library (System settings->Reset media library) then update the X3 to the latest firmware.
3. After updating to the latest firmware, try updating the media library again.
Q: Why does my .wav files not play?
A: Please check using Foobar2000 or other capable software on the computer to see whether the wave file is actually DTS or Dolby encoded multichannel audio, or perhaps a wave file of bit depth over 32 bits (8bit below and 32Above bit files are not always supported).
Q: Why does my .ape files not play?
A: APE comes in 5 levels of compression, including Fast, Normal, High, Extra High and Insane.
Extra High and Insane encoded APEs are not supported while Normal and High encoded APEs are only supported at 96k/24bit or below.
Q: Does the X3 support cue sheets?
A: The X3 supports external cue sheets for identifying and playing a cue'd music file as separate tracks.
Q: Why is my cue sheet not supported?
A: Embedded cue sheets are not supported. Also please make sure that the .cue file is named the same as the music file that it cues and they are put under the same directory.
Q: Why does X3 not show the cue file in the micro SD card when browsing files?
A: Since it has been already been used by the X3 to split the cue'd file into multiple tracks (which are shown).
Q: How do you set it to shuffle play across different folders?
A: Set the “Play mode” to shuffle and “Play through folders” to ON. Then after updating the media library, enter the All Songs list in the Category menu and choose any song to start playing.
Q: Why do my lyrics not show?
A: The X3 only supports external .lrc files, named after the music file it lyricizes. And please confirm the Lyrics display setting is set to ON.
Q: Why am I seeing rubbish characters?
A: Only ANSI, Unicode and UTF-8 (with and without BOM) encodings are supported for ID3 tags and .lrc files to be read by the X3. If the ID3 tags and / or lyrics files are encoded in an unsupported format, rubbish characters will be shown.
Q: Why do my new songs not appear under any category?
A: The X3 can only sort your new songs into these categories after they have been added into the media library database. Please set the Update Media Library setting to automatic, or manually update the media library after adding your new songs.
Q: Why does the total number of files displayed by X3 differ from the actual number of files that I copied into the micro SD card?
A: The total number displayed by the X3 indicates the total number of files playable by the X3.
5. Other Operations
Q: How to get longer battery life for the X3?
A: 1. Turn on "Idle standby". When this is set to on, the player will enter standby after the set time when no music is playing and the user does not press any buttons on the player.
2. Lower the backlight brightness to reduce power consumption.
3. Set the "Screen timeout" timer, so that the player turns off the screen and locks the keys automatically after the set delay when no buttons have been pressed and the scroll wheel hasn't been turned.
Q: Why is the X3 sometimes sluggish in responding?
A: 1. High bitrate lossless tracks, particularly 192k/24bit APEs or DSD files, 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 first to make it easier on the player. The sound quality will be the same.
2. Placing too many songs on the X3 may also contribute to slowdowns. Please limit the number of songs on the X3's micro SD card where possible.
3. Placing non-music related files on X3's micro SD cards, such as videos and pictures, may cause the X3 to slow down while sifting through them looking for music files. It is recommended to dedicate the micro SD card on the X3 to music.
4. Playing high bitrate files or DSD files from slow micro SD card may cause stuttering. Class 6 or above genuine micro SD cards are recommended.
5. Unpredictable ordering of files, such as placing several .ape and .cue files in the same directory.
The following directory structure is recommended: create separate folders for albums by the same artist, and open subfolders within each artist folder to hold single albums in separate subfolders.
6. A mixture of music files of several different codecs and sample rates may also slow down the player. It is recommended to place files of different codecs and sample rates into separate folders and to play files of the same type in sequence from these folders, to prevent the X3 from having to switch between different decoders frequently.
Q: Why does the X3 get a bit hot in operation?
A:The X3 utilizes an SoC with high clock speed, a separate DAC, and (also separately) a high power headphone amplifier and independent analog volume control in the amplification stage, thus dissipating way more power than consumer DAPs typically performing computation, DAC and amplification all on the SoC. Apart from outputting more power to your headphones, a lot of this power is also dissipated as heat, thus causing the X3 to heat up slightly in operation; but this does not endanger the X3 or the listener in any way.
6. Connecting to other audio devices
Q: How do you connect the X3's line output (LO) to other audio devices?
A: The X3's LO is a standard line out that is designed to be connected to external headphone amplifiers, car audio systems, home theater systems, powered speakers, etc. The LO provides sound at a very high volume when either set to a fixed-level output or at the higher levels of the adjustable output option, which can damage your hearing if you listen to headphones in this output mode. Please set the output mode to Headphone output before listening to headphones with the
Q: How to utilize the X3’s coaxial digital output?
A: 1. Set the X3’s Select ouput to “Coax out” mode.
2. Use the provided 3.5mm coaxial adapter cable to obtain a standard RCA coaxial output port and connect to the coaxial input of your S/PDIF coaxial digital-compatible receiving device using a standard coaxial RCA cable.
Q: Could X3 be used with FiiO's docking station?
A: X3 could be used with FiiO's docking station DK1 and desktop amplifier K5 via Micro USB connection.
