I only expect basically that the headset / headphones deliver reasonably bearable music.
I fortunately get much more!
For sound:
The music sounds consistently very good; perhaps not so finely tuned as my 'Medusa NX' or the 'Roccat Kave', but basically completely audible, even for the more demanding music lovers.
If you like loud bass, can rejoice: If desired, you get quite the rush will get an earful. I was very pleasantly surprised to get as much depth index for small money.
To technology and processing:
Personally, I find the basic appearance of the 'Sharkoon Rush' very rickety and at first glance little confidence. The earpieces schlackern but very on the bracket when you hold the set in hand.
Fortunately, this first impression will not last, because this circumstance is merely cosmetic. Sits the headset pointing to the head, nothing rattles.
Otherwise, only good things to report:
The microphone is, thanks partly flexible microphone boom, very accurately adjustable.
Also it can not fold down or slip unintentionally, since it is similar to a mouse wheel, with a (quite strong) 'screening' which allows precise adjustment.
The cable of the set is provided with stable and regular, knick bracing at the seams.
The earpieces are just right to my ears - they close my ears and do not press (despite glasses). The headset headband is easily adjustable to the size of the wearer.
For me it is also located after 2 hours still very comfortable and makes jerky head movements without having to slip.
The Rush also has a small cable remote control, via the on and off the microphone, and the volume can be controlled. Very handy thing that, if you for instance just talking in Skype and in the same room with 2 different people - easy micro silent and there is no confusion with the interlocutor.
I have not paid 14 euros including shipping and am (by now two weeks continuous use) with the necessary for this good value for more than satisfied. Therefore, there is of me for this moderately priced stereo headset unrestricted buy recommendation.
