post #1 of 3
Thread Starter 

This is a ear pad mods, which will improve bass like a subwoofer :L3000:

 

You can try this "subwoofer" before actual do this mod by pull out both cups so the ear pads just over your ears (recommend song test: Why not me of Enrique Iglesias), you will noticed an extended sweet rumble bass :eek:

 

I did this mods with:

 

- Thick foam

- Double side adhesive tap

- Small scissors

- Knife

 

Step 1:

 

Took out the mounting ring and glue it to the foam with adhesive tap. Use the knife cut the foam with the ring shape (outer circle)

Step 2:

 

Apply the adhesive tap to the other side of the foam, cut inner circle ring.

 

 

Step 3:

 

Attach the ear pad to foam, use the scissors cut some holes on the foam (i did 16 holes) so that you can have a clean rumble bass

 

Foam attach to the pad mount ring

 

 

Step 4:

 

Plug it back and enjoy :beerchug:

This or anything similar to this causes a 100 Hz hump, and rapid roll-off below 100 Hz, just so you know.

Thanks Jerg for pointing that out.

 

But after using this ear pads mods couple days, I'm so addicted to the new bass :wink_face: 

 

However, it has been falling apart because the adhesive tap can not do it job :angry_face: so I've been experimented on other mods:

 

- Thick HifiMan Pleather earpads: add some soft cotton between foam ring and fabric ==> improve comfortable vs stock pleather & same sound

 

- Combine Velour and Pleather ==> super comfortable & beautiful sound (bass enhanced) :ksc75smile:

 

Step 1: remove the foam ring (easy to deform) and cut fabric of the Pleather pads

 

Remove inner foam ring and fabric

 

 

Step 2: Sew Pleather on top of Velour

 

ear pads mods

Note: I did not sew complete circle so it will not get hot/humid for long use period
