I expected a stronger vibration, so that it would be directly felt. Wrong. But it works well, the bass is very juicy. When 7.1 is on, it is hard to hear other people in the voice. When turned off, surround sound works worse. For a day or two I learned to understand what people say) But you can get the hang of it. I use it strictly without my own microphone, so I can’t comment on it.
