I now have:

In black
I tried nitrous that usually does nothing for me and I felt tingling and a very strange feeling kinda like my brain was flexing (like if you shake sheet metal)
and my eyes kept trying to open.
They have a range of 7Hz-22kHz... so I can hear all the "higher then human hearing" tones.
are these good ones??
