You'll hear sparkle, something I call "treble percussion."  There's a cool energy to unfiltered HF.  The veil is lifted.  It's worth it.  The resulting sound is cleaner.


If you have medium-long hair I wouldn't recommend taking off the front cloth. If you do hairs get in and touch the driver = not good. I didn't notice an increase in clarity in the 2 days I had the cloth off (I broke them after 2 days). YMMV

 

Without the front cloth, your drivers are more exposed to hairs or just plain dust.  The remedy is simple: Blow lightly over them and they're as right as rain.

i need to post these in the grado mods section when i get some pictures tonight. I just bought a dk brown jmoney headband for my 325s. I never really like the goldies so I took the cups and soaked them in easy off oven cleaner to remove the anodizied gold layer off of them. I also removed the reference series ring from them. They look pretty post apocalyptic and I think since the anodizied layed is gone, they are going to oxidize and turn out nice when they do. Anywho, pictures would help and i dont have any at work. Ill post later.

FWIW- I only plan to remove that cloth coating, I still have my flat pads soild-no hole. I found it very uncomfortable cut out and find the flats very nice, plus, they keep my ears warm in a cold house all winter.

I ordered a pair of SR60i's yesterday and I haven't been this excited over an audio purchase EVER...I'm just so curious to see what they sound like after you start tinkering with them. My first pair of headphones were SR60 and I loved them to bits. I lost them in a house fire though....messed around with other brands like AKG and beyer but they never came close to the unique sound grado produced.  I guess that's another reason why I'm so excited, I'll be part of team grado again gs1000.gif

Epic.

^That's a really cute pic...I can imagine two benefits, baby's ears would stay nice n' toasty...and baby wouldn't roll out of bed at night :)

 

But about your question...on my 325i I noticed sweeter airier highs (especially cymbals) and more high freq detail.

I'd be interested to see what you come up with for a front grill. Will you also make that out of wood? I could imagine that the material and hole choice, etc could have noticeable sonic consequences.

 

- and boy oh boy do I ever need to learn how to quote two different people from two different post into one reply...I blame my Mac computer.

Protecting your baby's hearing is also an important and frequently overlooked precaution (though admittedly open AKGs won't do all that much in terms of isolation).

Currently, I use window screen.  There are several ways to do this.  Screen material can be cut to form a circle just bigger than the driver.  This allows the screen to be wrapped around the sides of the driver, forming a shim.  A less ambitious method is to simply cut the screen material just large enough to fit onto the wooden hat, then glue it on.  A sneakier method I've used was to insert the screen into the cushion, which avoids the need to secure it to the cups.  This works like a charm.

I've given some thought to the use of wood as a screen material.  I had some cups made by a woodworker, years ago, who made the grills out of wood.  They ended up looking like salt and pepper shakers but the wood quality was enhanced.  I don't remember whether it was too much of a good thing, but it doesn't take much to make a workable and effective grill.  The key is to protect the drivers from being wrinkled because the mylar is exceptionally flimsy.  

 

A single crossbeam, about the width of a toothpick, could go a long way toward protecting the driver without veiling the highs.  A pair of these, strategically placed, would be more than enough to get the job done.  Whatever resonance wood would generate, it would still be a vast improvement upon the plastic nightmare it replaced.  Having seen the inside of these plastic dungeons, undamped and sonically bankrupt, I think protecting the driver can be done any number of ways without sinking to the level of this horrible plastic grill.

^I was thinking of the toothpick idea too. But maybe a little larger diameter, like about 1/8 of an inch or 3/16ths, and maybe about 4 or 5 of them in parallel fashion. That would (might) keep little wondering fingers away from the diaphragm but might allow them to still be popped out for any cleaning, crease fixing, etc. 

 

But attaching the screen to the back of the pad is a neat and even more convenient idea...bravo.

The cans were never turned on while he had them on, too dangerous even at low volumes- projecting sound so close to the ears for a developing newborn. Not my baby either....

post #461 of 5003

Bilavideo,

Just wanted to say thank you for this amazing thread. I have had a pair of Grado S60's for about 11 years now. While I have always enjoyed them, I felt like they were missing a little bit of bass, more so after I replaced the comfy pads a few years ago with the bowl pads. After reading through this thread, I took the plunge and began the improvement process. I used a hair dryer to separate the cups. The folks at Grado must have used extra glue on mine because it took about 5-6 minutes of heat and quite a bit of pulling to get them apart. Once done, I used a dime to trace circles on the "felt feet" I got at Home Deport. A dime seems to be the perfect size. One thing I did not see you mention that I did was dip a q-tip in alcohol and clean the back of the driver and plastic grill to make sure the felt adhered well. I vented 4 holes at 4, 6, 8, and 10 o'clock positions. I could not use 9 and 3 as 3 was blocked by the solder connections. Once all done I put the phones back together, plugged them into my ipod and wow was I surprised. I don't have the audio vocabulary to explain the difference in sound but boy do they sound great! I definitely hear more bass. Not "boomy" but definitely more pronounced. Anyway, I just wanted to say thank you and to encourage any other folks that have thought about doing the mods but have been hesitant to try. Keep up the great work.

Without the front cloth, your drivers are more exposed to hairs or just plain dust.  The remedy is simple: Blow lightly over them and they're as right as rain.
 


I understand this, but the hair on my head physically touches the driver, causing it to wrinkle and rattle. Just a warning to the folks with long hair.

I've got a hair mod, if you like. ;-)

This is a quote from page 1, but I have both Dynamat and felt, so I decided to test it. I'm not very good at describing sound changes, but I'll do my best.

 

Yesterday, I took apart my new sr60is and noticed that the back of the driver looked different than my old sr80is. This concerned me, but they sound identical to me, so I went ahead and damped the back plate and surrounding plastic with felt. The result wasn't subtle. The High Frequencies (HF) seemed to be better balanced with the rest of the sound. They seemed to be better balanced than before. I didn't notice any other changes in the other frequency ranges.

 

Today, I took the felt off and put Dynamat on. The result surprised me. The HF decreased (slightly), and the mids seemed more forward. An even smoother sound overall. Less of the "needles on your ears." Bass was the same.

 

I haven't poked holes in the back yet, however I plan on poking maybe 2-3 holes to bring the bass up slightly.

 

I quite like the sound right now, and hopefully woodies live up to my expectations. gs1000.gif

I'm not cutting my hair for headphones. That's one line I don't plan on crossing.
