The packaging is quite appealing. As you can see, it lets users see the headset and provides basic info.
We found a rubber plug inside the box and it's used to seal off the 3.5mm microphone connector, in case you take the mic off of course. There's also a small pad listing key features and although there's no mention of how to take the mic off, we're sure users won't have trouble figuring that out on their own. Of course, we'll show it anyways.
The in-line controller is visible through the plastic window on the package. The remote comes with volume control and microphone On/Off key.
The in-line controller is about 39cm away from the phones. Its placement is well thought out and once the headset is in use, the controller is more or less level with the keyboard, and it can be reached easily.
The cable is some 193cm, which is 7cm less than it says on the box. Still, it was long enough to reach our case, and we routed it behind the table. The cable looks well made and it splits in two at the end - one connector for the headphones and the other for the mic. The mic is omnidirectional and it's nice that it has a dedicated connector, which means you can use it independently in other programs as well.
We would've preferred if Cooler Master marked the connectors a bit clearer. A little rubber bump or symbol would've done the trick as well, because users could tell by touch. We advise you to mark them yourself and save yourself time later.
When using the Sonuz as headphones, on a cellphone for instance, a portion of the cable with the mic connector will hang in the air.
