The bass is deep without spill-over into the mids. The midrange is so smooth, clear and balanced with the bass and treble - neither too forward nor recessed. The treble range is extended further than my previous efforts without the least bit of harshness. I can hear chimes, bells, high hats, and brushes on snares/cymbals very easily for the first time out out of modded T50's. There is a greater sense of space between notes and more airiness in female vocals, as well as the treble range, than my previous mods. This modded set's level of detail and clarity is impressive and performs effortlessly. It's easy to tune the bass ports and the ear pads for the amount of bass I want; same for the high end. And it's all reversible.
I hope this is helpful....
Cotton balls pulled length-wise, silicone (?) bumpers, Paxmate, Dynamat, Claytoon plasticine. The package of plasticine on the right is unopened, the middle package shows how much was used in one previous set, and the white package is what's left after the current mods.
1. Stock driver felt and bass port felt remain in place.
2. Two strips of Dynamat in cup bottoms, only; pressed down firmly and dimpled with flat head screwdriver. I don't know if this has any effect but I had it laying around.
3. Plasticine applied all the way from the driver perimeter to baffle outer ring. I pressed this in very firmly and tapered outward. I believe the extra mass loading is in large measure responsible for the remarkable improvements I'm hearing as I type this post. They are not heavy - I split 1.33 oz. between the two baffles but this is 4 or 5 times the amount if you only apply plasticine flush within the baffle compartments.
4. Baffle equalization vents remain open: 1 open through-and-through the baffle and 3 semi-open/covered by the dust cover on the ear side of the baffles.
5. Paxmate cut to fit entire cup interior except the bass ports which remain open --> I did not remove the stock bass port felt.
6. I added Paxmate to the central cup compartment to tune to my preferences.
7. Furniture bumper added to increase treble extension. This worked great.
8. Not shown: I pulled apart 4 cotton balls, each forming cotton log. I placed 2 of these under the back half of each stock ear pad and the difference is striking. Reducing or adding more padding changes the external chamber volume with favorable SQ mods to suit your preferences.
EDIT: Armaegis suggested using cotton gauze instead of cotton balls. I rolled up some and pushed them under the stock ear pads. The sound improvement from top to bottom is similar to pulled cotton balls without the messiness of cotton fibers everywhere.
I'm diggin' it.
That's all I have...no secrets...nothing held back.
