I believe it was purchased at Radio Shack, was given to me as a gift by relative.
And made by 'Hoffco'
There was a time when I was in favor of the big operator wrap around head type of headsets, but not anymore, cause previous two models I owned both just stopped working, stopped communicating with Android or Iphone or whatever.
Now I own smaller headset, which I prefer.
I'll share the brand later, as well as other wrap around headset that just suddenly stopped working that's popular with truckers and others who work in loud industrial areas.
