It completely eliminates any noise from the television in the next room. Son unas chanclas estupendas, de muy buen material y de marca. I definitely miss having them and will be buying them again when I got some money together to repurchase. I have used these several times since I got them. UPDATE ON REVIEW! Love this assortment for bracelets strung with occasional spacers. Love . Its beautifully made, fits well and has a nice unique design. The volume is definitely not as loud, which many people probably wont notice. Definitely recommend 10/10.
