Exclusively designed dual feedback amplifier circuits create a warm tone of vacuum tubes, We pursue the warm and simple sound of vacuum tubes. Classical sketches sound very nostalgic, and vocals are more magnetic and emotional.
Three independent headphone amplifier circuits for maximum dynamics, lowest distortion and maximum drive. Whether your headphones have balanced TRRS 4.4mm plugs or TRS 6.3mm plugs, we've designed the amplifier circuit to drive your headphones with ease.
We use a volume controller made by ALPS in Japan to control the volume. Its extremely low noise characteristics can make the details of the music more perfect, and the volume control can be very smooth.
In order to protect the user's headphones, we have designed six groups of quick-response headphone protection circuits to detect the operation of the circuit at any time, Users don't need to worry about the headphones being damaged.
The three-stage variable gain adjustment can easily adapt from low-impedance and high-sensitivity IEMs to high-impedance earmuffs. Just connect the headphones and switch to the corresponding gain, and leave the rest to HAP-1.
