DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable.
While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.
Pair with Laptop via USB
A majority of people use a laptop as the primary source device to listen to music or watch movies. Since the laptop is an essential part of the audio chain there are headphones and devices designed to work a laptop or computer system flawlessly. With the availability of USB connectivity, it becomes easier to pair various devices like an Amp, DAC or even headphones without worrying about drivers or any additional piece of software.

EMBEDDED WITH ESS SABRE PRO DAC CHIP, MAKING THE FiiO KA1 AN ALL-ROUNDER
The FiiO KA1 is embedded with an ESS ES9281AC PRO DAC chip that combines the capabilities of a USB audio interface, DAC, and an amplifier into one device. When combined with the multi-layered HDI gold-plated PCB, the DAC results in lower distortions, higher efficiency, and lower power consumption, leading to a high-quality sound. The ES9281AC PRO DAC chip supports 32bit/384kHz PCM and DSD256 formats. You can access the DoP mode, which supports DSD 128, and the Native supports DSD256 playback. The FiiO allows you to hear even the minutest detail within your music and have an energetic listening experience.

The KA1 also has a premium audio amplification circuit that delivers ample power to the connected earphones to bring the best out of them. FiiO KA1 is also certified by MQA as it can render MQA files without any distortion. MQA rendering technology can connect to an MQA Core signal like TIDAL or FiiO Music App and complete the final stage of unfolding an MQA file. The FiiO offers you a highly engaging experience with a detailed and immersive sound.
ROBUST BUILD WITH AN ALL-METAL BUILD WITH RGB LIGHT INDICATOR MAKING IT AESTHETICALLY PLEASING

How to connect the FiiO KA1 to computers?
1. The FiiO KA1 can be used driver-free with computers of Windows 10 and above.
2. You can also install the FiiO USB driver. It supports ASIO output of up to DSD256.
FiiO USB DAC driver 5.30.0 version download link: Click here
3. If it is connected through the Type-C port, just use the Type-C edition of the KA1. If it is connected to a USB-A port, just use the USB-A to Type-C adapter to complete the connection.
4. Settings of the music app: choose the FiiO KA1/FiiO K series as the audio output device->put on headphones to enjoy music. For some computers, it is required to select the KA1 as the system audio output.
(Note: Since Microsoft has stopped driver authentication of systems below Windows10, the KA1 will not support Windows10 or below computers.)
【Mac】
1. The FiiO KA1 runs driver-free on macOS.
2. When connecting to the Type-C port on the computer, just use the Type-C edition of the KA1. If it is connected to a USB-A port, just use the USB-A to Type-C adapter to complete the connection.
3. Select the FiiO KA1 as the audio output device of the computer.
Does the FiiO KA1 support in-line control and answering phone calls?
2. Since different smartphones vary in USB phone call permissions, the in-line control and phone call functions of the KA1 are temporally unavailable.
3. An incoming call will be passed out through the speaker and microphone of the mobile phone. So you can pick up the phone to answer the call without unplugging the KA1.
DSD file support
2. To play DSD files on the computer, please use the software which supports DSD files (such as the Foobar 2000) and install the corresponding plug-in with correct settings.
3. Switch tracks of different sampling rates may cause obvious impulsing sound. This is a normal phenomenon. So it is recommended to classify music files.
