TriPad Microphone Stand Isolator
Isolates the microphone stand from studio floor - No real description on what "isolation" means and how it's done
Eliminates disruptive resonance from entering the mic - How does it eliminate?
Cleans up signal for less noise when recording - How do such puffs clean up the signal?
Improves clarity to deliver more natural sound - No comment, eh?
