Part from two details, the left side looks like the other. The cord departs from the left side and there is a hole in the middle of the earpad. This is where the microphone is connected to, if you want to chat in games or via Skype.
Here the microphone is connected to give an impression of how it is proportioned in comparison to the headset itself. As mentioned earlier, the microphone is very flexible and can be turned in any direction one might want to. The microphone cannot turn all the way round, as it has a stop block in both sides.
As ARENA has a very flexible headband, it is possible to twist the earpads all the way to one side and halfway the other. Again, it illustrates how large the earpads are in contrast to the headset itself. The cushions around the edges of the pads are incredibly soft and comfortable to have around the ears.
