I bought the headset to use it as a pure microphone together with my Beyerdynamic headphones to play and to talk via Skype. The sound quality I have therefore not been tested, but due to the relatively small ears, the sound is not good great. The microphone basically met its purpose, but offers little adjustment options and the voice quality was of my interlocutors with "sounds like an old phone" described.
For the price you can not expect miracles. The voice quality is not particularly good, but in the end does the product what it is. For those who do not need high-quality audio, but simply looking for an easy way to communicate the product is certainly a good thing, for me it is good, unfortunately, nothing.
