Up Close

As boasted by CM, the drivers are an impressive 53mm and are shrouded by large, softly padded earphones that should fit snugly over anyone's ears without any hassle.

The headset is adjustable on both sides and the microphone is situated on the left earcup as standard, however this is removable and can be plugged into either earphone to suit the end user’s requirements.

The CM Sonuz comes with a very lengthy 2 Metre long cable. A little down the line from the headset is an in-line volume remote with a microphone mute switch.

The connectivity of the Sonuz is basic, with only a headphone and microphone connection. CM haven't labelled these connections, so you may need to pay some attention to the coloured stripe on the plug itself – something that is perhaps a small oversight on CM’s part, given that a lot of people may struggle to see the different colours when installing the plugs at the back of a PC.

When testing audio equipment, the end result is always going to be subjective, which makes it imperative not to judge a product too harshly or too fondly. That being said the CM Sonuz is a 'Good' headset that ticks most of the right boxes, but is let down a little from being a ‘Great’ headset by not ticking some of the more important ones.


The headset feels quite large and relatively lightweight, which can easily be interpreted as robust and well-built; however, I couldn't help but notice some of the plastics used in the construction felt a little ‘cheap’ – possibly a strategy used to keep some of the costs low, but quite noticeable nevertheless. With that being said, CM have made the effort to braid the cable very nicely and gold plate the connectors - which adds to the feeling that a good amount of thought and consideration has been put into its design and functionality.


The Sonuz is a pleasure to wear, as the ear cups feel breathable and comfortable, whilst the microphone is suitably positioned a few inches from the face - ideal for those who use in-game communication applications to speak to friends, or those who use VOIP applications, because the headset didn't pick up the turbulent air sounds from my desk fan or of me breathing.


Whilst testing the headset in a variety of games, I was pleased with the experience overall. Bass and mid-range sounds were deep and defined; however, I felt the sound at times, was a little ‘tinny’ and weak for my liking. Whilst watching movies, I was inclined to change some settings on the media player equalizer to enhance the sound a little more, particularly during busier moments, the sounds were felt to be a little flat.


The CM Sonuz is a good all-rounder, offering good sound for a competitive price. It’s basic connectivity is ultimately its biggest downfall. Though the large drivers sound impressive when listening to music, sadly during movies and games, the lack of 5.1 surround sound left a lot to be desired and with the Sonuz having gamers as a primary a target audience. I couldn't help but think those die-hard FPS fans would get frustrated at the lack of sound positioning provided by 5.1 & 7.1 connectivity . I also felt that it should be priced a little more competitively, as it can found for around the £60 mark at some e-tailers – a price only a few pounds away the likes of the Roccat Kave, that offers a much more impressive sound experience.

For those reasons, it has earned itself a Bronze award - If priced a little better, for example around the £40 mark - it may have earned itself a Silver award.
