I think its that I'm not used to having my ears touch the pads. It's been years since I've owned a pair of grados. I'll likely get used to them.
I tried the pleather pads, but they are fairly thin and my ears touch the felt of the driver. A slightly thicker pleather pad may do the trick, but I'm not sure they are available for HD662-EVO.

Pleather ramps the bass a bit.
Great pity if you find them irritating. The bass on these is quite profound in depth. They go incredibly low.
After seeing some posts on here today, I had a play with my coffee filter and that felt that was glued on originally. I think the felt is helping to control the highs. Hard to tell because it takes a while to swap around and memory isn't good enough.
The velour pads are very good and have a lighter bass touch than the pleather, but in actual fact, the bass still hits incredibly low and hard with them as well. The modding is incredibly easy to do and I'm pretty sure now that the covering of four vents on the baffle does something to the mids. They become more natural to me. Even just covering the vents and leaving out the paper or felt over the drivers sounds pretty good to me, so I think the felt is doing something. I put it back just to have a listen.
I just used electrical tape straight over the holes on the baffle and it literally took minutes to do. The simplicity of the mods is unbelievable and similar to the T50 mods.

I just finished the mods and agree - it creates and outstanding headphone!!! Stock, I found them a bit too bright actually. With the mod, they provide a much "smoother" (perhaps cohesive is the better word) presentation.
The issue with the pads is really that my ears are fairly small -- so they fit completely inside the ear pad. With relatively "thin" pads, my ears will touch the drivers.
Removing the felt glued to the drivers and replacing with toilet paper has reduced the irritation. I can live with these.
Thank you Frans!!

I think it is safe to say that those buying an HD662-EVO should remove the felt disc in front of the driver and apply 1, 2 or more plies of (the softer 3-4 ply) toilet paper, tape off 4 of the 6 'paper covered holes' using electrical tape and mount velours pads to make it sound 'better'.
All reversible mods... glueing back the felt (why would one want to) takes more effort to undo. The proto I got didn't have the felt disc.

I think the felt disc slightly altered the treble, but not as much as tissue. It's difficult, going from memory.
I wonder whether Superlux decided on that felt after seeing the tissue mod. It would also have been pretty easy to have only left two vents open on the headphone since it does as Tim says, makes the headphone more cohesive.
Glad you find it more comfortable, Tim.

I'll know in a week or so.
Ordered a production one. Would like to have a spare of those and could always sell it onwards.
My article isn't 'relevant' any more when they changed the final product so ... re-measure and re-write the article. ... dammit.
Can compare the modified prototype I have to a modified production one as well.

Can compare the modified prototype I have to a modified production one as well. As long as they're fairly consistent in the manufacture process! From your photos, nothing looks as though it's changed except for the glued on felt disc. The vents might not have been an easy thing for them to change perhaps? Their machinery might be geared up to make 6 holes and that's it!! I found the mod affected the mids really positively and brought the sound more into focus so that the bass became part of the main body of sound rather than a separate entity..... The embarrassing thing is that I think in many ways, these are outdoing way more expensive headphones.

Cohesive is the word I wish I had thought of When I listened to them stock it was as if about three different volumes of the music were arriving at the same headphones. I edged a bit of the new felt away and when I saw everything looked the same as Frans' phics off it went. I hope Frans' tests don't come to a different conclusion! Syd

That doesn't worry me Syd. Probably what you were hearing is exactly what Fran's graph suggests. Raised bass, raised mid, raised treble. I heard it the other way around. (Then again, I hear imaging backwards in any case) I heard two suckouts instead of three humps!!! Having said that, I found the mids slightly strange. I felt that they were actually recessed but it may have been some kind of tonal thing. I also felt a bit of Sony V6 thinness in the sound. After covering the vents, the mids seemed to become more natural sounding and the bass went a little more seamlessly with the rest. I still do find the bass quite big, but actually, I like that a lot. I don't think I'm exactly a basshead, since I don't like it bloated. I like a lot of bass, but right down in the gut so that it completely disappears with mens' voices, showing no bloom. (Mid bass stuff) So although I like a good healthy bass, I think it's the depth of it that I crave in many headphones. The Superlux really digs low but to me, it's also raised, but that's not a bad thing for me!! That's hopefully not a difference between the released model and Fran's review model ....... Measurements don't worry me at all. For me, it's the perceived sound on the head and the graph together that is more informative. I found it interesting that Frans saw three humps (if you like) and I was hearing two suckouts!! We'll soon see how the sold model differs, if at all. Time will tell.

Have been enjoying 'the Wall'. Not the Pink Floyd recording but from Roger Waters.
Very well recorded. Only some parts with very loud explosions are clipping.

Funnily enough, I got a copy of the same recording a couple of months ago, Frans. It is extremely good. I think I prefer it to the original which seems a bit too 'contained'.
I'm doing the same with the hd662 ..... Looking for recordings with deep bass. They really are quite amazing after mods. I'm back to velours again today. Bass is better that way. I presume you know 'Amused to Death' from Waters. That's quite a shock on the Superlux at certain points. If you have it, listen for the airplanes and then the missile that hits ......

Actually, I just listened to The Wall up to the 'We don't need no educashun' number and boy do these headphones light up. The bass is absolutely profound. Very speaker like and just brings that recording to life.
To me, they sound like a large floorstander and the impact that they give is just awesome.
Your mods make such a difference to them Frans. I can't stop listening on them.

I may have to pick that up. Looks like DVD or Blu-Ray only.
