I removed the fabric from both sides the second I got them. aswell as putting blu-tak over the front center hole in the magnet as a reverse reflex dot / horn plug. and then bitumen as a bass ring around front and rear of the driver.

And I noticed this with the 32ohms drivers as well. I swapped contacts and suddenly there was bass and clearer pronounced highs.

the fact that it suddenly brought my 120ohms to life proves that despite whether it "should" or "shouldn't", it does.

Not very detailed cans, I got bored of the relaxed presentation and moved on from them. I would still like to hear the EP one at some point though, most accounts have found them more fun sounding I believe.
I thought they were not detailed, MP was a bit grating, not flat (LP came somewhat close). I only see the EP as being worse even though I haven't heard it since all reports point to it being a bass monster, making it even more colored and probably less detailed than the MP. I honestly don't understand how the EP or MP could be considered to be used as studio headphones, even in the 70s or whenever they were made.

I am assuming by grating you felt they had a bump in the high frequencies? That would be consistent for me in a way, I don't really mind the treble in the 325i's at all. Perhaps I need to give an actual neutral phone a listen for a while... when I have money that is.

No, I don't. The treble was rolled off in the MP, less so in the LP but it still had some. Something in the midrange was grating and something in the bass was bloated and not good.

Sorry, I'm not trying to hate on the Sextetts, they just didn't do it for me at all.

Edit: You can always try getting an ortho for cheap and modding it to at least what you think is flat.

Hey, sounds good, and of course we need photos, etc.

Just keep in mind that what works for heavy ortho diaphragms is most likely going to be too much for a lightweight stat diaphragm, even if it's a fat old electret diaphragm.

Did I ever show anyone my K240 pads? or did they make it to HF when Tyre owned them?

Preezecktly.

It sounded to me like many middle-line headphones from the Seventies sounded. Not much bass, peaky treble, swayback midrange with lots of honky. But we also know that AKG production variation is rather (ahem) large, so my LP Sextett may not be yours. All I can tell you is I thought mine pooted. I got them for a good price sound unheard, so I'm glad I bought them, but I never listen to them.

Don't forget to check out the Ludo Search Engine and the Faustian Wikiphonia to help the S/N ratio. Did we ever persuade you to get hold of an ortho? No?

Yes, one of the nicest things about the orthos, most of 'em, is their tweakability. You can flatten 'em or you can honk 'em. You can bassmonstercize 'em or etherealize 'em.

As for the T20v2, I too thought my damping suggestion had too much bass bloat. When I get back to it, I'll remove the dot, try some denser materials, now that we know what they are and where to find them, and try again. Remember, a damping layer doesn't have to be thick, but it does need to be dense.

Any suggestions to bring the mid range out on the Pro 30?

The T20v2 I sent smeggy had well worn-in pads that didn't seal well and killed enough bass to almost make it sound flat stock. I'm not sure if that's a good thing, but I think it sounded pretty good, enough that I just left it that way when I listened.

Have you done the driver and vent damping? If so, consider the shallow "snoot" made of weatherstripping foam that Smeggy tried on some of his creations. This will have an effect similar to the one created by the foam rings on the Fostex T40v1.

Ah. My pads were in original smothery condition. They engulfed my ears, and just as 4lane said, even after some strenuous damping (for the time, anyway), there was still a bump up in the bass that made and still makes the 'phone sound half finished. With different pads, even slightly different pads, as we now know, we can wipe out the bass or make it overbearing. Pads don't change the character of the bass, though, and by that I mean transient response. With good diaphragm control, even too much bass sounds very nice. With bad control, too much is simply grotesque.

sorry to harp on this but this is the best description I have heard to describe why I think the YH1000 sounds the way it does. I will mention it no more ..dB

I got the EM6721 open. It was just held in by 3 screws underneath the glued earpads.

The electret is huge and the transformer is tiny. It's pretty much a closed-vented design, with three fairly large holes being the only places for air to move freely. There is already some sort of fabric between the three holes and the outside mesh. I think it's the same fabric that is used to keep the electret from touching the ears.

Yeah I did, added a reflex dot to the driver, I am going to play around with moving that around (behind a layer of felt) this week. I will look into the "snoot," thanks. What is considered the most neutral ortho (modded)?

Edit: No results for "snoot," I will head-fi stalk smeggy's posts in this thread and look around.

I have been working on that lately (Realistic Pro 30). Got some cheapo forsner bits, a vintage headphone, and some SFIs to play around with in a couple weeks as well.

Sorry, my original term for it was "snorkel", but somewhere I must've thought that would give people the wrong impression, so it became "snoot" today. Try here. and here. In fact, do a search for <weatherstrip*> and <smeggy>.

Received my YH-100 from HeadphoneAddict



Thanks to some regulars in this thread who have already offered modding suggestions. I think I am going to start with the Tomek mod illustrated in Faust3d's wiki. Wish me luck

Yaaay, YH-100! Don't forget to acquaint yourself with its stock sound before diving in. Report impressions of puzzlement and disgust back here, of course.

Will you be using another headphone as a kind of milepost during the mod?

I think I do have a good handle on how they sound stock. I see a lot of potential since there is plenty of bass quantity and the treble isn't completely hidden. The headband doesn't have as much clamping force as either of my HP-1s (and the YH-100 ear cups are larger distributing the pressure over a larger area), so that is really nice with long term listening.

I only have my stock Yamy HP-1 right now, so I'm not going to start the mods until I have my modded HP-1 back in my possession.

I love the modded HP-1, but the one thing I craved is more bass.
