The only minor bother is a very mild hum that can be heard when i pause what is playing on T.V.

I returned them once because of an annoying hum

Nothing, still loud humming.

Finally, there is a loud hum in the deadphones unless I set the headphone volume low and the TV volume quite high.

and then when finally plugged in, charged and working both sets had a steady hum in the ear piece.

The sound is clear, no hum or static

Very poor product that hums regardless of the source or the quality of the cables you purchase.

headphones had good range, but at whatever range, there was loud electronic hum, all the time

Always the loud hum

The hum was so loud I could not concentrate on the program.

If I turned up the volume enough the sound would drown out the annoying hum, but at that volume I couldn't listen very long

changing channels didn't ameliorate the hum.

Don't know why these RCA ones had the loud static/hum, thought it could be interference with other electronics, but the Sony ones are working perfectly, so I don't think that is it.

There is an annoying hum in the supplied set, which is not present in my old set

constant hum not worth what I payed

No matter what I did I couldn't eliminate an audible hum
