Limited to 600 pieces worldwide.


Product highlights


Within its compact design, Mjölnir achieves a 132dB signal-to-noise ratio, noise level below 0.8μV rms, and 134dB dynamic range on the foundation of 2.5W output power (per channel). Mjölnir features a fully separated multi-layer PCB circuit design, a multi-processor architecture, independent power supply and an independent 3mm thick locked-in shield. It fully unleashes the AK4499EQ’s ultimate performance.


It exhibits effortless control for high-sensitivity earphones and high-impedance headphones. It offers 3.5mm unbalanced, 4.4mm balanced, 6.35mm unbalanced, and 4-pin XLR balanced ports to cater to a wide range of audio devices and ensure compatibility with various headphone options.


It also supports Wi-Fi streaming for Roon (currently undergoing certification), bidirectional Bluetooth connection, digital input for desktop devices, USB connection for computers and phones, digital output for AV amplifiers, digital output to DACs, balanced/unbalanced analogue output for active speakers, and output to amplifiers.


The three-axis toggle switch provides a better tactile feel and user experience, reducing errors in blind operation. The precise positioning knob ensures clear selection of output channels with distinct feedback. The volume control knob offers effortless operation and improved control capability.


The 97Wh energy from six “21700” cells provides a continuous and stable abundant power supply of 20V 3A internally. Playback time ranges from 8 to 15 hours (depending on gain, screen operation, headphone impedance, and other specific conditions).



A beautiful custom tailored leather carrying bag is accompanied by the purchase of the Mjölnir, providing convenience for transportation and protection during storage.
