”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.

Unlock the key to great sound from your smartphone, with the Cyrus soundKey.

Rated 4 out of 5 by from Good quality DAC Generally, this DAC will provide an improvement in sound quality to most of the mobile devices it's designed to work with. I've used it with a variety of headphones ( including Sennheiser HD598's, Koss Porta-Pro's, etc) and I'd say it gives very listenable results with all genres of music. For the cost ( I paid 49 quid) you can't go wrong.

Rated 5 out of 5 by from Soundkey I bought this product as a gift for my sin. Sound is more clear now from headphones and from our hi-fi system

Rated 5 out of 5 by from Great portable DAC/headphone amp I mostly listen to Spotify premium on my phone on the go, using wireless Bluetooth Sony Wh-1000mx2 headphones. I was looking for a sonic upgrade and a friendly member of RS staff recommended this little gadget as the best value for money. I could definitely hear the improvement of the sound quality with better dynamism and a wider soundstage. It doesn't drain too much of my phone's battery. Warmly recommended.

Rated 4 out of 5 by from Significant Improvement in Sound I got this for Christmas this year and I was really pleasantly surprised at the improvement in quality of the audio whilst using it. The volume is the most noticeable boost here, but there's a massive clarity difference when using it also. I'm on Android, so the setup was easy as the soundkey came with both a steel-braided USB-C and micro USB cable (my phone, the Huawei P20 Pro uses USB-C). When testing it with and without the soundkey, there's a noticeable improvement when using the key on bass heft and also a really nice treble boost without it being too strong. One caveat is that the ringtone/notification sounds get the same boost so that, when you're least expecting it, a text could literally make you jump off the couch! Turn those down if using headphones - trust me! Overall, it's a bargain at its current price and well worth it if you want a decent sound quality boost without breaking the bank.

Rated 5 out of 5 by from Simple, effective, hi-res solution If you want to get into hi-res streaming but are not ready for a big outlay then this is great. Gives options going forward if you spend some serious money I.e. improve your mobile audio.

Rated 5 out of 5 by from Excellent sound and simple to use I bought this to drive my new Schure 425s and the fidelity and clarity is wonderful. I'm enjoying some back catalogue tunes for the 'first' time for the second time :-)
