Plays just about every lossless music format.
Flawless sound on the go.

Lossless playback for

Searching for the lost sound

As time marched on,
methods of sound recording have progressed from wax cylinders to open-reel tape,
LP records and eventually CDs and DVDs in the digital era.
Today, lossy audio as exemplified by mp3s have become the mainstream.

But as our methods of storing recordings become more portable and convenient,
the sound goes through more and more lossy transformations
from the recording studio, through compression and format and bitrate conversions.
The final sound that reaches our ear is no longer true to the melodious live sound.

After years of research and development, today FiiO is pleased to announce
a hi-definition portable player that supports all five major lossless audio codecs
at up to 192k/24b master tape quality, allowing those who love music and love it
in high fidelity to find the sound they have been missing at long last.

Five main
Lossless music formats

The X3 supports all 5 major lossless music formats:
Added support for HE-AAC, MP3 CUE and
32bit/64bit/floating point music tracks.
This makes its format compatibility the most complete
among hi-end portable music players.
With the X3, music lovers worldwide need not worry
about music format compatibility or format
conversions anymore.
Even Apple’s proprietary ALAC lossless codec
is decoded flawlessly on the X3.

Supports 192K/24B
Asynchronous USB DAC function

With update to firmware 2.05 and up, X3 can be used as an outboard USB DAC,
Supporting up to 192kHz/24bit input.

HD music at
master tape quality

As digital audio technology advances,
more and more audiophiles are buying and storing music in lossless format.
And to get the clearest original sound,
music lovers spare no effort in hunting for digital master tapes
at 192kHz/24bit. Thanks to our R&D efforts,
X3 supports master tape quality at 192kHz/24bit to bring you
unprecedented hi-res music enjoyment.

Light-weight portable player
with high sound quality

The X3’s dimensions are 55x109x16mm and only weighs 122g. Compared with other audiophile music players, its small size and light weight make enjoying music whenever and wherever possible.

10 hours playback time
& standard USB smart charging

The 3000mA built-in lithium polymer battery guarantees
extra long playback time of 10 hours. Whether you’re
taking a train or plane trip or mountain hiking,a fully-
charged battery can provide a full day’s music enjoyment.
What’s more, with standard USB port used for charging,
you need not mess with looking for a particular adapter.
At home, on the go or at the office,
it’s easy to get it recharged via PC USB ports,
USB power adapters or mobile power chargers.
No need to bulk your bag up with a dedicated adapter
for your slim player when going out.

Note: 10 hours was the result obtained with
          beta firmware.In the future, we can prolong
          its playing time via firmware optimization.

Dedicated professional
High Quality DAC chip

Unlike other consumer music players and smartphones,
the X3 does not use the DAC function of its
main controller SoC; instead, for the best sound effect,
it adopts the professional WM8740 DAC chip,
designed by Wolfson Microelectronics plc
of England. This is the same DAC used in
the Rega Saturn (top-end CD player),
the Sony PHA-1 (amp & DAC) and
the iRiver AK100 (HiFi player).
Apart from excellent objective performance,
its subjective sound quality is also widely approved
by industry reviewers and consumers alike.

High dynamic and current
output amplifier

Just like its DAC chip, rather than using
the integrated amplifier of its main controller SoC,
the X3 adopts the AD8397 as its separate amplifier chip
This is a high current op-amp
capable of outputting 300mA into 16Ω headphones.
Moreover, thanks to its high bias current,
the AD8397’s output sound quality closely-resembles
Class-A amplifiers, with warm timbre and
dynamic bass.

Hardware bass
and treble adjustment circuit

Many other players provide sound equalization or bass
and trebleadjustment function using DSP technology.
Though DSP EQ can target narrow frequency bands,
this comes at the cost of noticeable phase distortion.

After processing by the EQ software,
the sound is no longer natural.
The X3 implements bass and treble
controlsusing dedicated analogue hardware
circuits.The result is natural and effortless
tone adjustments that do not sound “processed”.

Dedicated to
music appreciation

Though the main controller SoC in the X3 is powerful enough
to operate a whole Android system,
the X3 was custom built for music appreciation.
Therefore, no UI clutter was wasted on playing videos,
games and whatnot. Instead, apart from
common player functions like playing by genre or album,
album art and lyrics display, the X3 also provides
gapless playback, and settings on power-up volume and
maximum volume limit to provide better, safer and
more convenient music enjoyment.

Multiple ports for
more entertainment

The X3 is well furnished with multiple output ports
including headphone out, line out and coaxial digital output.
Not only can it be used as a full-featured standalone HD music player,
it can also serve as a an analog source component to outboard amplifiers such our
own Mont Blanc (E12) to drive power hungry headphones .
Moreover, it can also serve as a digital source component and invites a more powerful
DAC to further improve the sound experience by connecting to the X3
through its coaxial digital output.
