Best way to pair headphone + subwoofer ?

thanks. it does tie up with what the audio store told me. they believe if we listen anything on the headset we would unlikely hear the paired subwoofer. Thus the subwoofer would only be felt as vibration, not sounds. ( would be nice if anyone who have such setup comment on it )

If that is true, then using something like kor fx vibrating vest could not only in theory achieve as well as a subwoofer, but it can even do it silently and with 3D perception as a bonus.

thanks again for the recommendation and feedback. i have placed my order and waiting for the vest now. will share my feedbacks once received it.
