| ”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.

| The DacMagic Plus has fantastic new features including wireless device connectivity and stunning audio performance from music of all formats. Thanks to twin DACs it instantly improves audio fidelity from all your favourite digital products allowing you to make your computer, TV, Blu-ray player and other devices a true part of your hi-fi system.
PURE PROCESS
The DacMagic Plus works by taking a direct digital audio signal from your computer, TV or other device - bypassing their built-in digital to analogue converters.
This signal is then carefully analysed and upgraded using our ATF2 upsampling system. Once this process is complete, the DacMagic Plus outputs your music as a much purer analogue signal straight to your amplifier.
Custom developed by our dedicated team in the heart of London, DacMagic Plus is totally flexible and supports digital music of all formats. It even allows you to upgrade 24-bit music files stored on your PC for better-than-CD performance from your digital music collection.
Watch the video opposite to find out why our proprietary ATF2 upsampling technology makes such a difference to the sound produced by our DACs.

Digital to Analogue Converter
Thanks to a Wolfson 24-bit DAC, a 24-bit/96kHz driverless USB Audio 1.0 input and S/PDIF and TosLink digital inputs, the DacMagic 100 takes the sound from your computer, iPod, TV and other digital devices and adds detail, depth and added clarity to give you a true audio experience.
Generally the digital to analogue converter found in typical digital devices is pretty poor and won’t extract the truest quality of audio from your sources. The DacMagic 100 works by taking a direct digital audio signal from your device to bypass its soundcard or DAC. It then digitally processes the audio signal using our custom designed technology, dramatically improving sound quality and reducing distortion. This results in greater detail, sparkling clarity and a deeper scale to all of your audio.

This Adapter Cable supports resolutions up to 1920 x 1080 (1080p Full HD) including 720p and 1600 x 1200 for HDTV monitors or projectors. The gold-plated HDMI connectors provide wear and corrosion resistance to ensure a long lifespan.
HDMI Male to VGA Female Video Converter Adapter Cable for PC Laptop HDTV Projectors and other HDMI Input Devices:
- Supports resolutions up to 1920 x 1080 (1080p Full HD) including 720p and 1600 x 1200 for HDTV monitors or projectors
- Gold-plated HDMI connectors provide wear and corrosion resistance to ensure a long lifespan
- With this version, we added a standby function to lower the energy consumption
- On the past design of HDMI to VGA converters, if HDMI port was connected to the device, VGA port will keep working, now, we added an environmental friendly standby function to make sure when there are no signal outputs from VGA, convertor will be at a low energy consumption, in the meanwhile to produce less heats
- Lower energy consumption, heat-reduced, extends the life of the product; after receiving customer’s feedback that the product will get overheated, we improved the operating current of the product to lower from 220mA to 120mA
- More stable performance and not easy to skip the screen, we improved the design of chips, mainboard and circuit to make it more stable when transmitting signal
