After getting these bad boys setup and running, the first song I went to was Kansas' Carry on Wayward Son. And right after that intro, when these things trigger on from the bass... WOW.It sounds weird, but it kinda turns your body into the speaker in a really tingly relaxing sort of way.It's hard to describe the feeling cause it's MORE than a haptic vibration, these things are in sync with the notes and music, the strength of the bass, drums, everything low tones and it sends the pulse up your leg through your body in this surreal way. I know it sounds corny, but I kept listening to songs and the longer I listened the more I just zoned out into the music. I've heard these songs 100's of time and it was like listening to them for the first time.Anyway, next thing I went to was the scene from Endgame when Cap picks up the hammer and deals some justice out to the mad titan. Everything was to be expected, another mind-blowing feeling, BUT when he hits him with lightning, only the right shoe vibrated cause it was on the right side of the screen IN SYNC WITH THE AUDIO. I don't know how they did it, but that was a nice touch.Plus these things make me like 3 inches taller with is great too. True to size. Good quality.I set my delay to 165ms and purchased the low-latency kit they offer too so I'm gonna try these out on Doom when the kit arrives. I'll edit when those show up.
