COuld be a grounding issue. Place a ground plug on your computer where it plugs into the wall outlet. You can get these at almost any store for about a $1.
Otherwise, you might try using a battery backup system.

There is a white noise hiss after every sound that comes through the headphones.The sound decays over approx 1.5 seconds. Have tried moving the base around the room, spent $$$ on high quality connection...

Maybe changing channels will do the trick. The noise your hearing is like a distortion of frequency from a nearby device that is using the same frequency the headphones uses.

How to disassemble sony mdr 7506 headphones to replace the earpads

I find that most headphones have to be opened up by going in through the part that fits to your ear. You might have use force to remove the foam covering, with that gone you should see a few screws.

My sony mdr-7506 headphones stopped working, anyway to fix them, i love them

As long as there is no inbuilt amp or something special to this make, then the problem will be most likely the cable or the Jack plug at the end. There will have a clean break (internal) cutting off all sound. If you are good with a soldering iron then you should be able to get a new cable with plug, or you can try cutting the old jack and fitting a new plug. If you need to go inside to fit the cable then the access screws will be under the foam and ear pads.

Sony 7506 Headphone Replacement Drivers

One of the channels on my MDR-7506 gets a little fuzzy in the bass intermittently, too. It's got a sound like there's just some hair or something in there; it doesn't sound like an electrical noise. This is not a very professional solution, but I found the problem goes away if I give it a good tap with my finger, right on the driver (the part that faces your ear). No need to remove the covers or anything. The delicate parts of the driver are well protected from something as blunt as your finger. As long as you're not pounding on it or jamming things into it, there's no danger of doing more damage. In mine the symptom is a minor inconvenience, so I'm not inclined to buy new ones yet. I heard that special ordering each driver from Sony costs almost as much as a whole new unit, so repair isn't cost-effective if the driver really needs to be replaced.

As for replacement, well, for durable, multi-purpose headphones with great range at a reasonable price, the MDR-7506 can't be beat. Some people say they think the high end is too bright on these, and the low as well, but if you've got normal patterns of hearing loss, you probably need the slight boosts, IMHO. Just don't switch to anything else without testing them out with your own music first; if you go shopping for something different, go to a store that lets you test the phones and bring some CDs and/or a portable player with music you're familiar with.

How to Rewire Sony MDR-7506 headphones

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)

On my MDR-7506, there are 4 screws, not one. Slip the ear pads off (they should pull off intact; don't worry) and the screws should be visible on the face of the driver housing. Remove the screws and you'll gain access to the wiring behind the drivers. You'll see the right side driver's 2 wires attached to the back of the left driver. I believe the ground wire is gold and the signal wire is red. In my case, my right driver is the one that's gone silent on me, and the culprit appears to be a frayed ground wire over on the left side. It's frayed right where the 'bare' (micro-insulated) wire leading from the left driver enters the protective black tubing that leads to the right. There might be just enough slack to cut and resolder it, but there's no margin for error. Does anybody have tips for working with these very fine wires?

A service "manual" (really more of a parts list / exploded view) is here (for now).
