Replacing Ear Pads on Beyerdynamic Headphones

Beyerdynamic DT 531 / 801 / 811 / 831 / 901 / 911 / 931

This article explains how to replace the ear pads on the above listed Beyerdynamic headphones, and the surprise I had after replacing the ear pads on my old DT531s.

Originally I thought it would simply be a case of pulling the old ear pads off and putting the new ones on. However, although not difficult, it wasn’t quite as straight forward as this. As the instructions that came with the ear pads were not very clear, and an Internet search provided no further information, I produced the following guidelines.

Here are my aged DT531s, in dire need of new ear pads. The black foam that should be at the center of each ear pad perished long ago, so I had put some thin black foam there in its place, to extend the life of the ear pads a little longer, but removed it for this photograph.

Your ear pad replacement pack should look something like this. You will most likely have to order it from a source that supplies Beyer products, and expect to pay in the region of £30.

First, remove the ear cup from the clamp by gently pulling each side of the clamp at the point where it enters the cup. The ear cup easily detaches from the clamp.

Next, I chose to pull the old ear pad off. Here you can see the ear pad coming away from the cup. Again this is relatively easy, and requires little force.

Separating the clamping ring from the cup.

The instructions recommend using a dull knife, and not a screwdriver, to separate the clamping ring from the housing. However, my dull knives were too thick so I had to resort to a small screwdriver. Great care must be taken not to scratch the housing at this stage. Work the clamping ring loose with the screwdriver using the minimum amount of force so as not to break it. (The clamping ring is a snap fit).

If the transducer separates from the cup after the clamping ring has been removed, as shown in this photograph, simply return it into position. The clamping ring will hold it in place when everything is reassembled (using an adhesive would make further maintenance, such as transducer or cable replacement, difficult).

This photo shows the separated parts: the headband, terminating in the clamp that holds the cup in place, the transducer and housing (bottom left), and the clamping ring (top left).

Put the new pad on the clamping ring. The instructions recommend using a hairdryer to soften the plastic that has to flip over the clamping ring. I found it was possible to fold the plastic back, bring the ear pad into contact with the clamping ring, and then flip the plastic back onto the ring. This is easy to begin with, but requires a bit of strength and manual dexterity to get the final part over the ring. This photograph shows the rear of the ear pad with the black plastic around the edge not yet flipped back.

With the ear pad over the clamping ring, insert the black foam that goes in the middle of, but behind, the clamping ring. It is held in place by the clamping ring once the ring is mated with the cup.

Place the cup face down on a table and, using even force around the edge of the cup, snap the ring back in place.

With the cup reattached to the headband, having taken care not to twist the cable, the job is half complete. Repeat the procedure with the other cup.

With the new ear pads fitted I wanted to quickly check to see that the headphones were still working, and that I hadn’t inadvertently damaged anything. Of course, the headphones were more comfortable with their new pads but, much to my surprise, the sound was significantly better too, so much so that I spent the next two hours listening to tracks from my favourite CDs!
