Title: Small and useful
Review: I suspected that my old Plantronix switcher was the cause of static and hum people said was there when it was muted so bought this. It's smaller, has more features and in my early tests, had no hum so I'm happy! Now to see if it will last. Most of my Plantronix stuff lasts a year then self destructs. I use headsets every day so taking them on and off wears out those wires that are so small you can hardly see them.
Is the review positive or negative?
