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. Then 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.
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 any outside interference has a significant negative impact on the sound. Specifically, the X3 Mark III uses three different PCBs one for the digital processing, one for analog amplification, and yet one more for Bluetooth. This guarantees an outstanding experience regardless of if you go wireless or wired.
