Grado BASSHEAD Mod.... - Page 18

Not sure if anyone addressed this already.  I just got the 225i's, and found this thread reading up on mods.  Sounded good to me, went off and got some electrical tape but then read that it leaves a crappy residue if you decided to take them off.  If you want to avoid that, like I did, try this.  I cut one length of tape that would fit all the way around with about a half inch to spare, and then a second piece that would just reach around with no extra.  Carefully place the two sticky sides facing each other, and then wrap the strip around the pad using the extra half inch to fasten.  For the most part the tacky stuff is only touching tape and not the foam.  

For my part I can say I hear a bit more punch with the bass.  Not a ton, but you get that slight impact a bit more.  I like it.  Great idea.

Has anyone tried gaffer tape?  It's basically a pliable duct tape with synthetic adhesive, so it holds strong, but doesn't leave any sticky residue.

heres something for you guys to think about...

drop down to your stationary store, pick up some clear or coloured plastic files (the very think kind of slotting in notes).

measure the diameter of your pad and cut a strip of plastic out of the file.

tape the strip of plastic around your pad, and voila~!

it works. i did it. no picks cos after 2 years i removed it, to see the difference in colour of my pads. i might do it again on some new pads though.. was a significant improvement on the bass.

Finally tried this mod on my Grado SR-225i headphones w/Mapletree EAR+ HD amp using plain black electrical tape one time around the circumference.

Pros: More bass impact. Especially noticeable with electronica, bass guitar, low piano notes, baritone voices, etc.

Cons: Loss of air/detail/clarity/spatial separation.

Overall interesting and worth giving a try, but I did not find the tradeoff to be worth it for this particular headphone. Grados are all about the top end sparkle.

I know this is an ancient thread with too much posts to back read. :) if this is a repeat post, please pardon me.

I read in one of the posts that the tape mod was not a worthy sacrifice and reverted to the inverted bowls mod despite it being uncomfortable.

I'm have an SR80i(came with comfies). i Did the reversed quarter mod on it, but was not very satisfied. I bought a pair of bowls and inverted them, very good sound but it was very itchy and unfortable. just an hour ago, i decided to ruin my comfies by fitting them around the inverted bowls. 

This is how they it looks now:

How it sounds?   A little more punchy bass than the inverted bowls plus the comfort of the comfies :)  

^^^^^ apologies to bump an OLLLLLDDDDD thread. 

but the mod posted above is pure win, it should get more credit. 

wow. has it been that long? hehe.

Its amazing how tinkering you can be when you only have a Grado.

Here's how the SR80i looks a year after:

Mods:

1. blu-tak[ed] driver

2. replace back grill

3. removed front cloth

4. felt lined back chamber[from furniture footing pads]

5. Comfies glued to the pleather pads for the purpose of attaching the pads to the driver assembly

6. Monoprice headphone pleather pads.

Result: Tight bass, tamed highs,less forward [aggressive mids] and soundstage like you can't believe its a Grado Prestige

I'm trying a slightly different approach to the tape mob, I purchased some rubber dip coating for tool handles, I used a small brush to apply it to the edges, it has been soaking in , so I will apply a few extra coats once it has dried and see how it sounds. This is a permanent mod to the pads, but I think this is close to what Tyll was talking about. After the 1st coat they looked pretty much normal, so it's a stealth mod if it works, and since it might take multiple coats, some tuning could be done my applying just the right amount until a pretty solid seal is formed.
 

great idea!

Been listening to the modded stock pads and one unexpected benefit has been revealed, my main complaint was the comfort, the phones would directly touch a small part of my ear, just outside of the ear canal, and after a few hours it would feel raw. The modded pads are a bit stiffer from the rubber in the edge, now they don't completely compress on my ear, just sitting slightly off my ears, so no rude pressure to cause a hot spot. The bass is improved, enough that recordings have a more balanced feel with more authority in the lower registers. I have also removed the SR325i buttons on the outside screens, it seems to give a bit smoother high end with a bit less of the Grado bite, a more relaxed top end, but only just perceivable to my ears. The rubber has contracted the outer diameter of the pads, giving the outside edge a bit of a concave shape. Ill include pics to illustrate.

I applied one more coat, you can see some unevenness, with some foam showing through the rubber, its drying as I type this. The product cures very quickly, so wait times between testing is less than an hour. Would be sort of funny, if I used them to soon and had permanent Grado ear muffs, talk about a good seal !
