Besgoods USB 3.0 Cable Male to Male, 2-Pack Braided 6ft USB to USB Cable Type A Male Double End USB Cord Compatible Hard Drive Enclosures, DVD Player, Laptop Cooler - Black

I read that this cord replaces dual dvd playerusb cords. i have purchased similar cords and they make a buzzing sound. will this cord have clear audio or buzzing? if it has the buzzing sound may i return it?

will these cables charge ear buds or power other like devices?

I am trying to connect a 32" TV to a computer to use as a monitor. Will this do the trick?

Are these cables 2m long or 6ft long? The product description says both but those two measurements are not the same
