Are these physically the same as the 662 EVO's? Because I can't wear those for more than an hour or so, then my ears hurt too much. The pads are a bit too thin, and my ears hit the foam covering the driver pretty hard.

Yes, same enclosure, same pads. Slightly different looks in the final version

They are here, received them a few hours ago from Thomann. The pleather pads are different - there is no longer a 2mm foam disc in front of the driver, now there's a very thin cloth sown into the pad. Also the velour pads are no longer included. Opened an ear-cup - there is no padding / wool behind the driver, so no changes made there. Also, compared to the prototype, out of the 6 port holes, only 5 are now covered by the paper like material.
Only had a few minutes for a quick listen - everything seems good, vocals are amazing. I think the 6-7k peak is still there, will test at home with some toilet paper. Now for the weird part - i changed the pleather pads and their thin cloth with the HD662 velour pads with their 2mm foam disc and the bass/subbass has increased considerably, it's now more pronounced than on HD662 (maybe due to the foam disc?). With the pleather pads, the bass is lower than on modified HD662. Could be that i'm wrong, it was just a first impression, will check at home.
Can't wait for Frans to measure and modify the retail model, i'm curious why they left a port opened (i guess it lowers the bass). @ Frans - thank you for everything, much appreciated.

If there is too much pressure, try this: Unfortunately, the pressure is fine, but there's just not enough room for my flappers Are there other brand pads that fit, and are thicker, without changing the sound (since the ear would be further removed from the driver)?

I think that solderdude may have measure it with pleather Evo's pads, different than the one mounted here. With velour and foam disk from Evo clarity seem lacking, there is too much bass. It may be that hole's fault ?

Didn't notice a problem with clarity and i'm not sure what effect the free port has. Might try to cover it at home. Only Frans can save us now

It sure need to be cover it, since the six holes in the proto was, but with what material ?

I ordered the HD688 and will see what mods are needed. They will most likely differ from the prototype. Also ordered the HD681EVO velourspads that may well be more 'leaky' like the pads on the HD688 ?
I assume the open hole is needed with those pads.
Give me 2 weeks to figure out which velourspads and or different mods need to be done. Wanted a spare HD688 anyway or maybe I will put the modified version up for sale here.
Did not buy the HD687 though, that may be more different in final design.
Looks like Superlux took my comments serious. Let's hope they start making more durable versions and more versatile (deeper pads, more adjustment range) and low microphonics cables.

Playing a bit with the EQ, for put down that FAT bass and gain something above 16Kh, with Evo's velour and 1 ply of toilet paper, i'm starting to understand the potential. At fist they leave me very unimpressed and the fit was so atrocious, on stock condition. With that much pressure and the internal tin cloth, the ears hurt after almost a second.
Before starting to mod the cups i need to understand what to do with that unneeded hole.

They do seem to have huge potential. I quite enjoy them on some tracks - i love the vocals, much better than on the HD662. I also got the 681/662 EVO velour pads, not sure if they changed them but they seem more dense than the ones that came with the HD662. Would the round HM5 pads fit/work? Using a decent Beyerdynamic cable right now, it reduces the microphonic issue but i think it's mostly caused by how the short cable is placed in the plastic housing. Otherwise, i have no comfort issues. superluc - do you have any issues with the 6-7k peak? seems fine on most tracks...not sure.

Before starting to mod the cups i need to understand what to do with that unneeded hole. Try covering lets say 50% of that hole with duct tape to see what effect it brings. On Takstar hi2050 I covered 40% of that hole for best balance between bass and mids and bass was less boomy, became more tight, punchy. Mids were not overblown with bass anymore and separation improved significantly. Here is track that I used: www.youtube.com/watch?v=hNVu55ZyC-Y From 2:05 if there is to much bass some sweet sounds will be flooded. For me Superlux headphones are overpriced junk. For similar price you can buy Takstar Pro 82 with build quality beyond Superlux dreams. Fool me once, shame on you. Fool me twice, shame on me. That flimsy mini jack failed twice and evo design is even worse than hd681. I don't have big ears but you should't have ears at all to use them comfortably. In comparasion to HD681 or HD669 the build quality looks the same but price was doubled. I understand that they give better pleather pads, because what can be worst than hd681 pads and new driver that cost them probably 50 cents more. Good job Superlux. I'm interested in different music experience that these headphones can provide but there is no way I will buy them with so low build quality. I will rather pay 100 euro for something more solid than deal again with that junk. Fixing everything what factory fail to produce right became boring. On top off that Supelux produce mostly monitoring headphones that aren't so much musical. Sound is very clear with good separation but because sound is so wide it sound something like that: briiytytaaaatytryring breyraayaaaeyyuing while the same stuff on musical headphones will sound more like: bring briing ;D You can catch every note when everything is more natural, coherent, tight unlike overdetailed sound. I was missing so much melody from my Superlux headphones because of that. Solderdude, I dont think that they listning you at all to be honest xD No velour pads that improved sq so much? What?

Otherwise, i have no comfort issues. superluc - do you have any issues with the 6-7k peak? seems fine on most tracks...not sure. Yes, it's the short cable. On my 681 Evo i have take that away, because i lose one channel and those internal wires needed to be soldered again, and then i have not feel the same kind of microphonics, even if i have use for doing that one of the cables from the package. In regard to the highs, with the paper i don't feel them peaky, just a hint of that sometimes, but i still need to mods the cups, so i don't have doubts on that. Take it with a grain of salt, but maybe i was expecting more air in the sound, even considering that the 681 Evo are semi-open and this ones closed, but i have try to put up a bit the EQ after 16Khz on the 688 and everything feel more as i want. Anyway, at now without EQ the bass is all over, and i'm not using a newer pair of pads, but the used velour of my 681.

Thanks for the tip, but we are talking about a hole covered with some paper-like material, in the prototype. It's just that i'm not sure of what to put on that, because i want to replicate solderdude's job, before think of try something different. Construction-wise yes, leaving the driver aside Superlux headphones are junk, but i like more a wide soundstage then something musical but congested.
