Optimized HiFi audio architecture | Independent flagship DAC
32Bit/768kHz DSD512 robust capacity | 3.5+4.4 dual headphone outputs
With most phones now foregoing a headphone jack, we felt compelled to create a headphone jack to truly bring back great sound.
Within the KA3's petite frame lies exceptional hardware.
Experience uncompromised audio quality with a carefully engineered multi-chip audio circuit.
Potently robust Dual headphone outputs
Comes equipped with 2 headphone outputs, both powerful to easily drive a variety of headphones.
32BIT/768KHZ | DSD512
Featuring abundant power with high signal-to-noise ratio, low distortion, and almost 0 noise - this is true high-fidelity sound.
>122DB SNR
<0.0008% THD+N
<1.7UV Noise
Satisfy multiple use cases with both a 3.5mm single-ended and a 4.4mm balanced output.
Compatible with various OSes like Android/iOS/Windows/Mac
Compatible with many devices like phones/tablets/computers/ audio players
Use in various scenarios like listening when commuting, in the home or office, or even gaming
*Due to the large output power of the KA3 and limited external power supply of iPhones, stutter and muteness may happen to the maximum volume.
* For Windows systems, please install the driver first.
The all-metal body sports a handsomely rugged design with distinct edges and a luxurious gold and black finish.
Besides exuding elegance, the RGB light indicator usefully indicates the current sampling rate.
blue - 48kHz and below sampling rate
yellow - 48kHz and above sampling rate
green - DSD
Unleash the KA3's potential with more interactivity in a control app including controls for 7 kinds of filters, high and low gain, and channel balance adjustment.
