and adequate for most home power tools, there's always one at hand. Be gentle with them, as the ear pieces are loosely bedded in rubber parts, plus, the headband can be broken. 
I repaired one with steel banding—wrapped with string, and epoxied—but could have replaced it with much less effort. 
Same story: there's one at hand, everywhere there's a project. Select for the best final-finish, as QC isn't what it could be. 
One loosened up, but got tightened with a steel punch strike to the center pin. 
While Harbor Freight says they are "on sale" I think this price can be beaten elsewhere. Notice HF is comparing prices with a brand not sold anywhere else—but HF!

I'm happy with my second $99 oil-lubed HF air compressor, but that model could use some noise suppression. (Hurricane Irma destroyed the first, identical, compressor).
BUT they started stocking those little Chinese Vise-Grips. Copied from the original design, they're a decent quality (for $1) and handy, even without the occasional need to grind the jaws to clamp something special or awkward. (Two in the left of the photo).
