Hi all.
In this thread I want to share the mod that provide more stable and reliable driver support against the back of the headphones housing.
This mod will likely solve the bass rattling issue for this HP model.
I came to this solution after my first bad experience with these HPs (they rattled and I returned them).
Then, awaiting another pair, I did some research about bass rattling problem and learned internal construction of these HPs.
So then the second pair arrived I already had idea of this mod.
And though the new HPs were not rattling I did this mod anyway because I don't like the default housing construction.
Ok now about the mod.
The idea I came with is to change the way how the back of the driver's frame is supported against the housing.
By default this is done by the small rubber o-ring bumper glued onto the back of the driver's frame.
When HPs assembled this rubber bumper pushes against 3 plastic pins from the housing.
The problems with such design are:
Some flat wooden or plastic tools and q-tips with alcohol will help here.
Next, you need to provide some alternative bumpers.
IMO the best solution in this case is to use 3 silicone cylindrical bumpers.
These bumpers are cut from the silicone hose and have the following dimensions:
Next, take these bumpers and put them onto the housing pins.
Because these cylindrical bumpers a bit taller than the housing pins this gap will provide reliable and springy support for the driver's frame.
Next, carefully reassemble the HPs.
You will notice much more tension when trying to snap the driver's frame into the housing.
Now let's see how this mod solves the problems stated above:

The problems with such design are:
- The bumper is too narrow and can be easily misaligned against the housing pins.
- The bumper's material has some memory effect and provide little overall tension between the driver's frame and the housing pins.
- There is glue.

Next, you need to provide some alternative bumpers.
IMO the best solution in this case is to use 3 silicone cylindrical bumpers.
These bumpers are cut from the silicone hose and have the following dimensions:
internal diameter = 3mm
outer diameter = 9mm
wall thickness = 3mm
height = 10mm
Next, take these bumpers and put them onto the housing pins.
Because these cylindrical bumpers a bit taller than the housing pins this gap will provide reliable and springy support for the driver's frame.
Next, carefully reassemble the HPs.
You will notice much more tension when trying to snap the driver's frame into the housing.
Now let's see how this mod solves the problems stated above:
- The overall contact surface of the bumpers is greater and the pressure distributed more evenly. The bumpers will always align correctly with the driver's frame.
- The silicone material is very consistent and reliable and will not degrade over time. It will provide constant reliable tension. You can vary the tension strength by changing bumper's height and/or wall thickness.
- There is no any glue.
