Plugfones are the only truly wireless patented Bluetooth hearing protection. This is not electronic noise cancelation, this is literally an ANSI rated earplug to block harmful noise. Did we mention how comfortable these are? We have to use earplug grade foam or silicone to give you hearing protection, but this translates into the most comfortable earbud experience there is. No hard plastic stuck in your ear that starts to hurt after a while. Plugfones also stay put because the earplug creates a seal in your ear. No more earbuds falling out! Premium audio with out the price tag! Plugfones are half the cost of other premium brands and with the Sovereign Duo they are even less than that per set. But just because they are less money doesn't mean we don't dial in our tuned speakers to give you a premium sound experience.
