2018 Best DAC Under £150
“A handsome difference to your on-the-go sound.”

"The soundKey can turn your mobile listening into an authentically high-fidelity experience."

SoundKey is an award winning revolution in mobile music. Hi-Fi streaming services like TIDAL mean fantastic quality is available to subscribers, but phones lack the necessary hardware to get the best from this data.

SoundKey unlocks that data, using years of Cyrus expertise in high-resolution DAC and amplifier design. Cyrus quality audio is now available to everyone.

Connect to your android phone, iPhone, laptop or tablet to unlock amazing sound. The components in SoundKey replace the audio processing and amplification of your phone, those components are the weak link in any mobile device.

Design Philosophy

Music is stored on your phone in various types of digital files. The DAC (Digital-to-Analogue Converter) in most phones, laptops and tablets is designed to hit a cost, that means it’s never going to deliver the kind of audio quality that your music files or streaming services are actually capable of delivering. SoundKey unlocks your audio, by accessing the raw digital files on your device and processes them using our special hi-fi DAC and amplifier. The analogue music output from SoundKey delivers much more detail, more impact and greater precision.
