Yeah I’m young…..71 yrs young….That'll be my neighbor across the street, who gave me a generous permission to dig as much as I want in her backyard… which needs a goddamn pickaxe even after weeks of rain
The built in speaker is muffled, that's a side effect of being waterproof and padded to withstand water pressure. What you're hearing through headphones is a true voice of your machine. You want it muffled too? Buy a set of sweat guards such as this one, it will smooth things out. I keep these on all my muffs, especially in the summer.
You must be young… Remember that setting where you adjust the actual tone frequency? Set it all the way up to 30.
I guess everyone hears things differently…I can hear higher pitches better
