Title: JUNK
Review: Sentry products are about as good as Coby products. Junk. Not only is there no highs, one channel of my earbuds stopped working after 3 weeks. There's no excuse for that. They were never misused. I will not buy another sentry product again. When I see the name, I'll keep looking like I do when I see Coby. They put out an inferior product. Burn me and that's it, you're done.
