New Grado Pad Mod that sounds great!

post #1 of 43
Thread Starter 
Ever since Ive been back into Grados around 2004 from having them on and off for ten years, it was really the first time I paid attention to how each pad affected performance on them. I have been satisfied by sr80s before that came stock with flat pads in 1994 and sr60s which came with comfies already in the late 90s but never really thought about why I felt the 80s were so much better than the sr60s to me at the time.

Then headfi came into my life in 2004... sorry about my wallet. Since reading the endless posts about different pads having different sound characteristics Ive always been wondering how each pad would make the sr60s sound and whether the sr60s with preferred pads could sound better to me than even the higher grados using the wrong pads. Well, sure enough that was the case. I found that I prefer even the less refined sr60s using flats to 325s using bowls just because the bowls add an unnatural effect to the upper mids that I really detest. Flats have their flaws too. Flats make the grados fart cannons with their bloated bass that makes the headphones also sound dark as an effect of having more bass. The stock comfies are okay in that they give a decent balance from lows to highs but lack the slightly bigger soundstage and detail of the bowls... Hmmm Now I was wondering how I could get a good middle ground. I tried quarter modded comfies(added a hole in the comfies) to get more treble... ehh it didnt quite work. It added clarity but also gave a less damped and more raucous sound. So I flipped the comfies with a hole in the center backwards... This type making the hole larger so that it could be done... I ended up with a better soundstage wow... I guess this mod makes the comfies equivalent to the yellow senn pad mod for the grados but in the end still found that the grados had a plasticky tone that was enhanced with those pads. Ok so now I was thinking what is this reversed bowls they were talking about... I flipped over the bowls to get the flat side to touch the ears and the concave part fixed to the frame. Now were talking... back to a more balanced sound like the comfies but with more detail than comfies and no more annoying upper mids that the standard fitted bowls sound. Ok I was satisfied for a few days then got the itch for other cans. THE END

Nope hehehe Joke only. Not the end yet. After some time has passed and having better cans around, going back to sr60s with whatever pad configuration I knew was not a satisfying experience and would make me always return the cans in the closet within five minutes of listening. I just couldnt stand the colorations typical of grados anymore. Then I was thinking well, I need to hear Kens rs1 during the EB in Manila to see if I am really done with Grados or not. Then came the day the meet came... RS1 on my head... less than 20 seconds I take it off because I hear the sound of the bowls that I instantly recognize. So before even getting used to the signature and appreciating the rs1s for the headphone that they are, I instantly gave up because I knew the sound of the bowls would always bother me in the end. So now I'm really thinking... Either my ears just dont match with grado/bowl combination or Grado just hasnt really put much thought into always redesigning his pads. I am not a headphone designer and might not qualify to say that grado needs to do more research about the pads but I know coloration when I hear it. It doesnt matter what grado it is, put bowl pads you get bowl sound, period.

So last night, I was just reminiscing about the meet in Manila and was thinking hey what was that sock pad I saw on a grado woody?! It was the MSpro. I didnt even think to try it at the time but keep seeing it on the meet pics. So I made myself some sock pads like those and fit them on my sr60. oohh wow bass! tight and lots of it! maybe too much hehehe and the details are too smoothed out. Maybe different material socks will matter but maybe also it is just the density of a whole length of rolled socks that keep the bass in there. Ok then I moved on and thought oh yeah... Density of pads=more bass/dynamics with the grados from remembering that the flats(more dense material) were more bassy than modded comfies(softer material) even though they had the same hole in the middle. Then I also remember people in headfi saying taped bowls add more bass. I'm guessing the tape makes it leak less bass out making the pads act like its denser. I said to myself theres one more pad configuration I havent tried (except for beyer C-pads). What about bowls inside out? instead of flipped over??? I did just that. So now the inside part of the pads are what shows out and not the back which was the reversed bowls I used to call. I wasnt really sure what they meant by reversed bowls in headfi but was thinking it was that backwards bowl with the square side pointing out.

Anyway, now with the inside of the bowls out instead of backward bowls(sort of like comparing a tshirt with the inside seams showing out vs just using it backward where the print goes to your back instead of the front) The sound is magnifico!!!! hehehe a little hyperbole there but now my sr60s are actually quite the performer. I havent listened to music this long from them for a long time. They have the bowls detail without the upper mids/lower treble nuisance. They have the flats punch without the overly bloated bass and the balance is better than the comfies with a little better soundstage to boot WOW, I'm impressed!!!
I really feel that listening to them this way is a step towards the right direction. I only wonder what this pad configuration will do to the higher end grados!!! :P

here is my sr60 with the bowls inside out...

That looks really cool! I guess I should try it out too.

Tried it and yes, it really does balance out the sound. Not exactly fugly and muddy boomfest like flats. Still, bit too much bass for my tastes (then again, I was just listening SA5000 so my ears adjust) but upper midrange amount is about correct. Treble is pretty rolled off though. And to get tonal balance between left and right is bit difficult, its hard to make the pads completely round.


*edit* Flipped the pads back (still pretty disfigured) and treble roll off is gone. Upper midrange glare is back though. I miss the bass fullness of inversed bowls, but bass is tighter and punchier and I prefer it that way. Nice pad mod though, people should try it.

This is very interesting, because it would seem that your mod causes the driver grill (w/ the white cloth covering) to press right up against your outer ear, and it would seem to me that would reduce the bowl's "seal" around your ear, thus reducing some bass response and definitely emphasizing the mid & upper response. But I haven't tried that, so I can't say for sure what the result is to my ear.

I have a mod for my MS1 (see my sig line with MS-100 link for pics) that goes in the opposite direction. It was inspired by the MS-1000 threads. I have plastic extenders (covered with black tape) that fit right over the cup housing, and I put the bowls on the extenders. I found a plastic aerosol can top that was the right diameter to slip over the grill cup, and cut it to about 1.25" depth. The bowls now completely surround my ears, and the grills do not touch my ear, increasing the soundstage and evening out the sound dynamics, IMO. The bass doesn't seem as deep as when the comfy pads are on, but it is very clean bass -- not boomy as with the comfy pads.

Maybe the bass is too much for the 225s. Its only just a little prominent for the sr60. About the balance from left to right, you have to get them perfectly similar on both sides I guess.

I just tried this on my HF2's and I'm pleasantly surprised! I'll have to do more listening, but it seems to bring the mids up and give them more warmth, the highs aren't as in your face, but the detail seems to be there. Bass is not as detailed.

Very enveloping sound. But more listening of course, could just be my mood

hehehe I was definitely surprised. Good enough that it made me actually listen to music on my sr60s again

x2 sounds pretty good on the hf2. Yea it does share both signatures of bowls and flats. The position on the ears seems to make a difference. I like it when my ears are inside the cups as the edge is now wider then bowls and much more comfortable. The sound does have the closeness of flats but bowls details. I also got some new tubes that may have helped too.

great mod don!
SQ change without incurring additional expenses

I wonder hos this will work on the GS1000's? Perhaps make them listenable at louder volumes.

hahahaha I dont know about that. The gs1ks are already supposedly bass monsters when used with standard bowls instead of the stock donuts

real men like bass

I feel they didn't have as much bass as people say they have. Sure they have bass, but not skull busting, mind blowing, knock your socks off bass. It has a lot of impact to it and that was it..

I mainly want to know if this will help tame the treble.. cause the phones are birghter than I would like.

Give them a whirl I guess. I wouldnt know how to predict the outcome for the gs1k but the lower treble is tamed on the sr60
