I was a bit unsure whether I should buy the adapter or not, have been missing since any reviews. So I definitely want to briefly talk about my experiences: The price is for the performance totally fine. I use the adapter with my external HD Creative Sound Blaster card and can not notice any problems. Both microphone and headphone adapter performs the problems his ministry. I can not recognize differences in sound quality (Sennheiser headphones, Modmic microphone). Processing convinced me.
