Shure SE846 Knowles Damper Modification
The Brown Knowles damper inside of cable insulation
Introduction
I would like to say a huge thank you to my friend
@csglinux for introducing me to the Knowles dampers by giving me some of the dampers at the last The Source AV Summer Series event. I have heard about the dampers, but didn't really think about them too much as I've been pretty busy with writing reviews and taking care of my baby daughter. I am really glad that
@csglinux talked about them to me and also glad that there is a difference to the sound of each pair of dampers that are much like the machined valve pairs of my Torque t096z IEM.

The acoustic impedances of the Knowles dampers are:

You'll need to use something like cable insulation for the dampers to insert into because the dampers are too small to fit in the SE846 nozzles. Also, once you do this, the cable insulated dampers can't fit into the SE846 nozzle inserts/filters, so you will need to insert only the damper into the nozzle and use each damper instead of the nozzle inserts/filters. I personally put the side of the damper that has the acoustic material the closest to the top inside the SE846 nozzle first.

Knowles damper sound impressions
Now, to the different color Knowles dampers, my listening results:
The Grey sounds a little muffled compared to the other dampers. You may hear it as bright, though.
White is slightly clearer in sound than the Grey.
Red is pretty vibrant and an enjoyable listen.
Green is a little warmer and enveloping. Also enjoyable.
Orange is more of a laid back sound...
...and Brown...Brown is magic. I love the Brown! A good second place is Red for me, but Brown is really, really good! Wow. Clear and vibrant, treble extends far to my ears, and is really enriching to my senses. Everything sounds so articulate and coherent. It's really cool how these different color dampers can change the sound so much - kind of like my Torque IEM with the 6 interchangeable valves. I even tried the Brown against my Black modded, which didn't sound as vibrant in comparison, and filterless (full After Burner), and that didn't have the same emotion and richness (but still highly detailed) sound of the Brown. The Brown is my favorite out of all of the Knowles dampers, nozzle inserts including modded, and filterless (full After Burner).
Add in a third party cable such as the Ted Allen Silver Litz, Sensaphonics Custom Sleeves - paired with your favorite source, and you have a combo that is simply amazing, to my ears.
To take out the Knowles damper: use a paper clip, making sure to angle the paper clip so you push only the cable insulated part of the damper, and not damage the actual damper or acoustic material in any way
Beautiful sound, in a small package
The SE846 has risen an even higher level now with regards to my enjoyment of the IEM.
Conclusion
For the price of the dampers, I would highly recommend them to every SE846 owner to help tailor the sound even more to your ears.
