      Cyrus soundKey improves your portable music vastly. If you are under the impression that plugging expensive headphones into your smartphone, tablet or laptop will produce adequate sound quality, you need to audition the Cyrus soundKey USB digital-to-analogue convertor.

      Affordable, compact and high performance

      What Hi-Fi?

      Music is stored on standard devices in various types of digital files. The DAC in most phones, laptops and tablets is designed to minimise cost That means it will never 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. With the analogue music output from soundKey that delivers much more detail, more impact and greater precision you will be able to hear sound quality you and your headphones deserve.

      Unbelievable sound quality.

      Perfect Portable Design
      Cyrus soundKey weighs around 16 grams, so it’s no extra burden on your pocket or bag. From a design perspective, smooth rounded edges enable it to feel more like an integral part of the cable without catching or snagging on anything.

      Extremely Low Power Demand
      Cyrus have not put a separate battery inside the Cyrus soundKey to keep it small, light and prevent you from having yet another thing you need to charge. It relies on the battery in the phone to provide it with power. Other DACs typically drain 100mA - Cyrus soundKey has been designed to draw only 50mA.
