From my experience, pretty good, just not what I wanted. Oh yeah, shipping was fast and free! Almost daily something goes wrong with the software that will force me to stop what I am using and fix the piece of trash. I waited a few days before making a comment just to be sure, and sure enough, they are awful. Fortunately, the dye on my feet does wash off. Parts of the product was broken and its cheaply made also. Think of it this way, we all have friends that want to borrow our headphones/earbuds but now if you share your earbuds with friends they can have their own dedicated set to use. The yoke holding an earcup to the headband connects to the headband with very thin plastic connector. I literally opened and closed hook 3 times and it chipped out from around hook. Ever since I started using cellphones, I have tried a number of headsets to (hopefully) improve the speech quality/clarity during phone conversations.
