  • What's Included
  • The PC is one of the most common ways to enjoy music these days, but the quality of the built-in audio is simply too noisy and poor in quality. The Firestone Audio BlackKey USB DAC is designed to fix that problem. Designed for both portable and home use, this USB DAC is the smallest option to increase the sound quality from your PC or laptop and is extremely cost effective too. Simply plug a USB cable into your PC or laptop and plug the other end of the USB cable into the BlackKey. Then plug in your headphones or computer speakers into the 3.5mm output on the other side of the USB DAC and enjoy. The unit will make your music sound cleaner with less jitter.

    There are two other Firestone Audio Keys in the series and each does something different. The GreenKey is a USB isolator and is designed to fix electrical noise issues coming through your USB connection. The RedKey is Firestone Audio's most compact 24Bit USB to S/PDIF Converter.


    A Digital to Analog Converter, also known as a DAC, is a device that converts a digital code to an analog signal. Most modern audio signals are stored in digital form (for example MP3s and CDs) and in order to be heard through speakers they must be converted into an analog signal. Most digital music players, such as a Smartphone or iPod, and PC sound cards come with internal DACs, although, they are very basic and do not deliver music in high resolution. Firestone Audio delivers a high quality DAC system with internal amplifier that allows you to play your music in high definition at the volume level that you desire. This system is the ideal peripheral for the music lover that stores their music library on their PC or Mac.
