Query: I bought a second pair.

I've purchased a number of: headphones, behind-the-neck headphones, and earbuds. The earbuds become painful after a short period of wearing them, some of them fall out easily. Many of the headphones feel like vises. Other behind-the-neck headphones move around too much or become dislodged from my ears when I move my head.I picked this up for just under $5. The volume is louder than most of the others I've bought. The ear pieces stay in place! I can move my head around and the ear pieces don't move. I was so pleased with them I purchased a second pair.
