After releasing the stereo headset Sonuz (tested here), CM Storm put on the shelves another 2.0 model, the Ceres 400. The biggest differences between the two peripherals are the size of the drivers (53 mm for the Sonuz versus 40 mm for the Ceres) and the lightweight design of the newer model. Both the Sonuz and the Ceres 400 are budget-conscious choices for those who don’t care about 5.1 surround sound models that are usually more expensive. We’ll first describe the Ceres, and then put it through the test.
