The main characteristic of the Ceres 400 is that it is a smaller (and cheaper) option for a 2.0 headset inside the CM Storm line than the Sonuz. It keeps the “big ear cups” style without being so clunky and heavy. The end result is a very comfortable headset for users who like circumaural pads.
The microphone is bendable, but it usually reverts to its normal position and must be bent again.
The control unit has a sliding button to mute the microphone that makes a noticeable click, so the user cannot hit it accidentally. The volume scroll could be a little bigger.
