| Content | ”It makes a handsome difference to your on-the-go sound.” ’What Hi-Fi?’ 2019 award-winner.
Improve the sound of your smartphone
The Cyrus soundKey uses a top quality DAC (Digital to Analogue Convertor) built into an ultra-low power circuit that lets you hugely improve the sound of your smartphone or tablet without rapidly draining the battery. Using a much better DAC than the one built into most smartphones and tablets means music sounds more dynamic, detailed and true-to-life.
Compatible with Hi-Res music files
A further bonus with the soundKey is that it’s compatible with Hi-Res music files up to 24 bit/96kHz. This means that, as well as MP3 and AAC files, it will also replay your Hi-Res FLAC files. Hi-Res makes the music sound more natural, with subtle detail easier to detect.
Ultra-low power consumption
A key advantage with this DAC over others is the extremely low power consumption. With a battery drain of less than 50 milliamps – under half the maximum recommended by Apple for use with their iOS devices – the soundKey is kind to your phone’s battery. What this means is a much longer phone battery life than when using other mini-DACs. The device itself is also battery-free.
Works with Windows 10, Android 5+ and iOS9+
Compatible with Windows, Android and Apple devices the soundKey is suitable for just about any smartphone. Simply make sure you have the correct USB OTG (On The Go) connection (Apple Camera Kit connection for Apple iOS devices) and you’re good to go.
Compact, robust and light
Crafted using high quality brushed aluminium, the soundKey is both lightweight and strong. Its sleek design combined with its compact dimensions and mere 18g weight make it perfect for music on the move.

Record Box E: Pure vinyl listening pleasure plus recording functionality!
Record Box E is an high-quality phono preamplifier, that offers the possibility to convert your valuable vinyls into computer music data. Record Box E accepts both MM & MC cartridges and gives audiophile music experience at an entry level price. The integrated A/D converter operates with Windows and MAC operating systems and connects via USB to your computer. Therefore your valuable vinyl collection can be digitised, especially for use in portable music players. Advanced circuitry and SMD construction keep noise and distortion at a surprisingly low level. A built-in internal shielding and an outboard DC power supply leave no risk for external interference. Because of its small casing, Record Box E can be placed near the turntable. Input and output sockets are gold-plated for preservation of quality. Record Box E can be connected easily to a line-input (AUX etc) of your amplifier.
