■Overwhelming high sound quality with AKM flagship DAC system
・Equipped with AKM's latest flagship separate DAC system "AK4191EQ + AK4499EX". By separating digital processing and analog processing at the chip level, the S/N ratio is dramatically improved, realizing a new generation of sound that is not only numerically improved but also has a focus on the texture of the sound.

■Desktop-class power in "Desktop mode"
・The newly installed "Desktop mode" and an independent Type-C port for power supply bypass the built-in battery when connected to a USB PD power adapter and run on an external power source. In balanced output + headphone mode, it delivers an incredible power of 1600mW, and can play a variety of IEMs to full-size headphones with the power of a desktop amplifier.

■High versatility to support all inputs
・Supports a wide range of decoding modes such as USB DAC, Bluetooth, and coaxial.

■Meticulous design and abundant functions
・Precisely designed 5-stage audio circuit and 5-stage gain control provide optimized sound quality from IEMs to full-size headphones. High accuracy and stability are achieved with 15 digital and analog power supplies and 21 low-noise linear regulators. Seven EQ presets and three customizable PEQ presets allow you to fine-tune the sound to your liking. It also features a "phone mode" that reduces smartphone battery consumption during calls, enhancing convenience.

■ Sophisticated design and comfortable use
- The design follows the top model Q7, and the back panel is the first to feature anti-glare glass that suppresses light reflections. The matte texture fits comfortably in the hand and prevents scratches and dirt. The golden ratio size of 18:9 provides a comfortable feel even when combined with other portable devices.
