The X3 Mark III has been certified by the Japan Audio Society to be “Hi-Res Audio” capable. With this, you can be sure that the X3 Mark III will grant you a natural and realistic listening experience.


Wider Soundstage from Balanced Output
The X3 Mark III contains both a 3.5mm single-ended headphone output as well as a 2.5mm balanced output, allowing you to experience two kinds of high-quality sound. The balanced output, never before seen in the X3, is specially designed to give a broader soundstage and extract more details from the music than ever before.

The music never stops, with Bluetooth 4.1t
The X3 Mark III’s Bluetooth 4.1 solution comes from the F1C81 chipset, which enables low-latency transmission to ensure that you will never miss a beat in getting your high-quality music.
The X3 Mark III supports a wide variety of lossless audio formats such as WAV, APE, WMA, FLAC, ALAC, DSF and DFF at sampling rates and audio bit depths up to 192kHz/32 bit, ensuring that you don’t have to worry whether you can even listen to a certain track while on the go.


Dual DACs for great sound wherever
You deserve better sound. The X3 Mark III makes sure you get it with its dual high-performance PCM5242 DACs. In its balanced implementation, these DACs allow for effective noise rejection and a higher signal-to-noise ratio (SNR). All of this means that your music will come to you in its purest form, free from any unwanted artifacts.

Independent DAC, LPF and amplifier for greater noise reduction
The X3 Mark III utilizes a design in which the DAC, low-pass filter (LPF), and headphone amplifier are all separated – greatly reducing the potential that any outside interference has a significant negative impact on the sound.
The X3 Mark III immediately captures your attention with its use of durable tempered glass and smoothly-cut aluminum frame. Its unique “sandwich” structure (composed of the front, the aluminum frame, and the rear) and its harmonious combination of colors give the X3 Mark III a delicate and chic look.


Carry your entire personal jukebox
The X3 Mark III now supports up to 256GB micro-SD cards, allowing you to carry thousands of songs with you on the go. In fact, this grants you the ability to bring over 8000 FLAC files, each 30MB in size. Feel free to carry around your entire personal jukebox wherever with the X3 Mark III at your side.

Wake up from deep sleep in a second
The X3 Mark III features both a new power-saving standby and a new deep-sleep mode, both allowing the X33 Mark III to wake up in an instant when called for. These new power-saving modes allow the X3 Mark III to standby for an astonishing 19 days, so that good music is always at your beck and call!
The X3 Mark III can also be used as a USB DAC capable of decoding up to 192kHz/24 bit audio. Furthermore, the new X3 is implemented as an asynchronous USB DAC, which is unsurpassed in terms of quality of sound reproduction.
*The USB DAC function is not available on macOS now, and will be realized by future firmware u update.
