The driver also has different damping, closer to that of the prototype HD687. Will do some measurements and exploratory experiments over the coming days. Quite certain it is a combination of pads, the hole and changes to the driver itself. All not resulting in improved response. Damn... they sure have listen to you

That's ok. I know that the rods can be bent more, i'm just a bit afraid of broke something, thinking also to the bad soldering the Evo's have on them.
I sincerely hope that solderdude's disappointment depends entirely from that hole.

I bended on my stomach Cups go side of ur ribs. Om quite thin guy... Don't bitching. It's my problem, not yours. It's not my fault if a difference of some mm hurt my ears. I have complain only for let that know that it may be a problem for some others, but we also already talked about the solutions. solderdude: there is an hole leave open on the right side of the driver

I have take some measurements with a caliper, for clear any doubts. The difference is less then i was thinking, nearly 1mm in the center vs the 681 Evo without the felt, and on par with the border, but the clamping force of the 688 is much much higher, so it may have take away some other mm, from the pads. I have already try to bend them a lot, but it's always not enough. EDIT: better leave them be, or i'll destroy those rods I don't know if the pair of yours doing this as well, but mine touching themselves, on the pads.

I think it's best to wait for measurements. Frans will surely compare stock pleather and velour pads since they have quite a significant impact on the sound. You could try to get 681EVO replacements pads, they seem more firm compared to the ones that came with the headphones. Not sure, might just be wear and tear. I have no issue with the fit of the HD688...small ears for the win And yes, velour is much better for me also, mostly because of the glasses. I guess you can solve the depth issue with new pads and maybe a spacer disk under the pads...maybe 5mm thick. Not sure if it would work, just an idea. Thanks but, as i have said i have already try them with my 681 Evo's velour. The spacer could be an idea, i did not think about it, and also i don't know how to make it This problem was very unexpected to me, who knew it that the 681 Evo have more inner depth. Anyway, the difference in depth between Evo's pads and HM5 is one cm, a lot if the temporary ones i have ordered are not too soft.

Thanks for the info guys, will try to get the XL version when it's available on amazon. Who knows when... As i can't used them longer with Evo's pads without hurt, for lack of depth, for starting i have decide to wait and order some cheap, not original nor XL, HM5 pads, that need to be stretched, and see in the wait solderdude's test and solutions. If then i upgrade to XL, it's either velour or hybrid, as i'm not a leather guy.

I want to get the Brainwavz velour pads - but which one? the regular or the XL version. Would both fit and the XL version would have more space? The Evo's pads are 105x105, 60 the inner, in between those two. 2 cm vs 3, in deepness. The regular may just be too small, even if you can stretch and fit them.

Look good, even if the silver circle is disappeared How much you have pay those pads ? If I recall correctly it was something like 45€. I had to pay taxes so price was bit high. Wow, only the best for your babies

Yes, they fit. Pads for Superlux Evo, AKG K240, Shure SRH-940 and Brainwavz HM5 fit also the 688. If you feel that there is not enough space between the ears and the driver, go with the Brainwavz.

Added some pictures with the Brainwavz XL sheepskin ear pads Look good, even if the silver circle is disappeared How much you have pay those pads ?

The 681 Evo is like this, near the short cable: 3 very tiny wires, left channel on the red wire coming from the internal, right channel on the free rod, ground on the rod where is the white wire.

Thanks. Oh well... it's a shame that the construction's engineering it's even worst thought than previous models, but with modding we can do it. The audio qualities of the driver deserve it. It's just that i wasn't expecting to have even this problem on them, and thinking about the fact that different pads affect the balance, well... the project goes a bit in a more personal way to find the balance wanted, and the budget is affected as well. Anyway, Superlux need to seriously rethink about what they want to do in the future, on the headphone's segment. We have choose to gave them a possibility with this headphone, but it's obviously that they can't go higher in price with something so cheaply constructed. Unless they want to produce and sell 681 and 668b until the end of time. A lot of audio enthusiast may say the same things of voa, build-wise, and see Superlux's headphone not as an audio bargain but more like plastic crap putted around a good driver. How deny that ? On the Evo's the headband may broke mostly because of the short height adjustment possibility, the internal soldering between the external male jack and headphone is bad, with so tiny wires, and it's the reason of those microphonics, the ear space on the 688 is ridiculous ( at least to me ) and solderdude find the one in the 671's prototype even worst. Seriously... why not have at least one top of the range model, with good build quality ?

I have putting again the velours pads on the 681 Evo... damn. Comfort is a personal thing, but space is objective.

Also these need better ear pads like Brainwavz XL sheepskins, fits like a glove And I was so damn suprised of sound stage / details. I did not expect to be this good. Angled or normal ? Those HM5 pads don't press too much each other on the lower part, if mounted on the 688 and leave them somewhere ? Are you using a stand for them ? If possible, i may be interested to see a pair of HM5 pads tested, because, after more use, i feel the ear space here much more problematic than in the 681 Evo. In the 688 the driver's shield is too close and protrusive, while in the stock 681 Evo it was in the rear, covered by the felt and obviously the pad's disk. Even taking away the felt and adding toilet paper, like i have do on mine pair of Evo, only the circle that previously hold the felt may tickle sometimes, at least on my ears, and the overall pressure is a lot less. But it's a mod, so it's mine fault if there is some contraindication in doing that. But here, and thinking about the awful fit on stock condition...
