DIY Privacy Headphones

I found a treasure pile in the hallway! There was a box labeled DONATE filled with old headphones.  You know the ones that plug into a junction box for a listening center - from, like, 15 years ago. You know the ones with the enormous jacks and the thick curly cords that are constantly tangled? You know the ones with sturdy plastic and comfy, padded ear covers?
I plucked them from the box, clipped the cords and voila, privacy headphones! No explanation needed. Kids love them and use them regularly. My only wish? I had one for each kid...
During Read to Self.
During a test.
During writing.
To get away from a classmate.
Saved from the landfill, and totally free,  privacy headphones are now a fixture in my room!
