Philips SHP9500 Cup Caps

thingiverse

These are cups specially designed for the Philips SHP9500 headphones to turn them from open to closed headphones whenever you want! While the sound signature does change a bit, and the soundstage will shrink [as you would expect if they suddenly became closed] - they still sound good - and isolation is much better. The process I used to dampen my cups was... coat / paint the inside of the cup with plasti-dip put a layer of sound-deadoning [or melamine] foam in the bottom. cover the foam with a thin layer of cotton [aprox 1 cotton ball pulled apart]. cut out and glue a layer of felt around the outside. place a small (5-10mm^2) piece of electrical tape as a treble reflector on the inside middle of the felt before gluing (or on the outside if you want to experiment). Adhere the retention rings to the outer rings of the headphone cups by the method of your choosing. I am not responsible for any damage you do to your headphones while attempting to apply or use this mod. Print Settings Rafts: Doesn't Matter Supports: Yes Resolution: .2-.3 Infill: 10-30% Notes: Suggestions: print the retention rings with support material, while support material is optional for the cups. making the cups taller / larger will give you more room for dampening, but also increase the size (duh) and make them less aesthetically pleasing. These could be modified to also work on other open headphones. the retention ring could be made taller and then use larger clips on the cups - this makes it easier to install and remove the cups and makes them more durable - but also makes the retention ring much more noticeable in daily use. Post-Printing After you finish printing these [a pair of each]... Finish the cups by damping them to your preference [see intro] adhere the retention ring to the headphones as desired. insert cups and twist clockwise to lock into place.
