Probably a bit late for the original poster, but just in case anyone else comes across this....
I also have the Sony MDR-RF4000K wireless headphones and the problem with the sound cutting out has got steadily worse over time, to the point where I felt like throwing them away. I replaced the batteries (use normal rechargeable AAs with a bit of card to trip the little switch that would normally be tripped by the Sony battery pack), however that had no effect on the problem.
After a little research I have established that the power on the headphones themselves is triggered by a pull switch in the right ear cup. When you put the headphones on, the padded headband is stretched and pulls the switch up, turning the headphones on. The headphones have always been a little big on me, and I can imagine that the headband has stretched permanently in the last few years, probably leading to the switch on being more marginal.
At any rate, although I don't have a fix, I now know that if the sound cuts out, I don't need to take the headphones off - just pull the headband up slightly on the right-hand side, or push the headphones as a whole down a bit, again on the right-hand side.

Okay, cut and strip the cord. There should be two copper wires and (on Sony headphones, at least) a red and a green strand. On a new 1/8" jack, there should be three connections. The middle one is left, and is where the green one goes. The short one on the side is right, and is where the red one goes. The long bit is the common, and is where the copper one goes. Before you solder, however, remember which strand is which, because you have to sand or burn off the colored enamel. (Use a fine grain paper, or use a standard lighter or stick match- anything else might damage or melt the wire)

You can go to Radio Shack and find some that fit. Although Sony does not sell them as they woudl ofcourse want you to purchase new ones you can buy third party cushions that fit.

Hello to all who have exhausted all avenues seeking instructions on how to remove and replace Ear Pads on Sony MDR-V6 Headphones.... All that is required is a little patience maybe some fingernails... The Pads simply slip on and off by pinching ends of cuff that is nearest the plastic backing of The Headphones by pulling them from their seat/flange .. i found it easiest to just roll the cuff off using my thumb w/rolling motion away from the plastic backing/housing of the headphones.. no tools required.. they are installed exactally like one would place a tire on a rim.. exact same motion is required as when removing a tire.. i can give no better illustruction than comparrison to tire removal and replacement. Be careful to make sure one end in completely set deeply into one side before attempting to pull opposing side over its side/flange..start on top and work way around to bottom or vise versa.. To get an idea of what you are attempting to do take a close look at new headphone pad rear and you will see the small flap of leather on rear .. there is a small overlap that fits perfectly over the flange.. dont try to force it as you may tear them...

You could try to use a player with a stereo balance and adjust that, but in reality you need new headphones. Sonys have very comfortable and flexible cabling but the downside is that they wear out easily.
