Phone headset buzz

What causes a buzz/hum on my land line phone? Interference?

Details: I got like four dozen fifty cent 2.5mm mono universal headsets a decade ago. (all my phones have a plug for them, except the new smarphones) On some occassions I get a buzzzing background sound, maybe mor elike a hum. On those occassions, using a fancier headphone eliminates the sound. Could the phone voltage be dropping because of the weather? One other suspect is a rechargeable DVD player nearby. Heater? Neigbor's equipment? Is it possible the magnets on the headsets are fading?

Any ideas?

The worst thing is "a ground on the line", ie. the insulation has a pinhole in it, and when the ground is wet, it makes a connection from one of the phone line wires to the earth. You can get crackling, buzzing, whistles and pops, as well as a completely dead line.

It can be at your property where the line is buried to the house, or in buried cables some miles away, between you and the central office.

Another problem can be corrosion on the wire junctions or in the lightning protector at your service entry.
