Considering the price of the microphone, my expectations were already set very low. Despite having low expectations already the microphone was very disappointing.
The box which toggles between mono and stereo mode made no difference (other than being a switch).
When plugged into my computer, simply plugging the microphone into the onboard sound card directly gave the same quality as running the microphone through the box and setting the switch to stereo mode.
In mono mode the microphone sounded absolutely atrocious. If you decided that you want to save a couple of euros and get this microphone don't bother with the switch box (which fortunately saves you some money on batteries).
The sound quality after plugging the microphone into my PC was not great. There was always background noise and it picked up too much ambient noise. The microphone is also extremely quiet. I applied the max amount of boost Windows allowed and my friends would still have to boost me even further through Teamspeak.
