OK, I just noticed that my left cup of my DT 770 seems to have a slight rattle problem. I am not sure if it's the driver or not. I haven't been listening any louder than usual. How can I take the cup apart? The velour pad seems to be glued to the cup. I also can't find any screw holes.

How do I fix this?

Perhaps it's the plastic not reacting well to the BOOM...

Either that, or it's your cans distorting slightly, causing rattling. Try turning it up louder and see if it starts buzzing. If so, that's it. Either listen quieter or lower the bass with an EQ.

You put a butter knife blade under where the black rubber is and twist the knife. You'll need a little pressure to put the pad back on because it truly "snaps" into place.

Chances are the driver is blown. When you remove the pad, look at the driver cover. It should not be broken, etc. I doubt that it is the wire(s) rattling inside.

Call up Beyer Dynamic in Long Island and see if they will repair under warranty.

OK so I got the pads off. What driver cover do you mean? The mesh cover? It's hard to tell if the driver is blown. How do I get the mesh cover off?

You don't get the mess cover off. Just make sure that there's no hair inside it.

The whole driver slips out and you can look inside the cup for debris or loose cotton, etc.

After you put it all back together also try the headphones on another amplifier - just in case. The other thing toi try is swapping the cables around. This should switch the channels - but you want to see if the "defect" follows it.

IMO, it isn't easy for a hair to get inside the driver, as it is fairly well protected, but if you're listening to the right stuff, you can distort these cans at normal listening volumes with a bass boost on. IMO, these cans never needed bass boost or loudness. Yes, you can blow drivers at reasonable listening levels.

Happens to me too. I sold them to someone who said he didn't care and wanted them without the repair. I'd send them in for repair so it gets fixed.

Cheers,
