They really are amazing value, Chris. It suggests that there are two suckouts. One at the top of the bass and one at the bottom of the treble. Yup, that's exactly it.

I just removed the pads from mine and there is a round piece of what appears to be synthetic felt about 1-2 mm thick on top of the driver - its glued in place. View AttachmentView AttachmentSorry for the phone quality images. Were these present of the review sample? Or is this something they added later on? If it is something they added recently it's interesting that they went with felt since in the measurements, it did almost nothing as far as i understand. I think i will just to the tape mod for now since i didn't notice any harsh treble yet. EDIT: in the end i went with 1 thin layer of tissue paper. Mine didn't have it. I suspect mine was a pre-prod model and they modified the production one. Perhaps only the 'tape 4 of the 6 holes shut' mod is the only thing that may be needed for the production model. Maybe they even did that as well already or used different 'paper' in front of the holes. Quite possible the felt does almost the same as the toilet paper. IME toilet paper is slightly more effective in that frequency area. I also tried the thick felt (which was in front of the driver of the HD681-EVO) on this one and it removed too much top-end. The toilet paper does not affect the top end that much. You could always remove the felt (glued on around the edge ?) and use 2 plies of toilet paper. If you prefer the felt or felt + TP you can always glue it back. I may have to order one myself from Thomann and see what they did ? Perhaps order a T50RPmk3 but that one is probably not much better than the modified T50RP I already have (2 of them)

I really can not say if they used different "paper" in front of the holes, it looks exactly the same to me compared to the pictures in the modifications guide - texture, thickness and placement.
I taped 4 out of the 6 holes and added 1 thin layer of paper, using the velour pads and there has been an improvement in the sound, especially the mids/vocals seem more natural. Can't say i feel the need to change anything at the moment.
If you ever have a chance to test a retail model and find that other mods may be more effective i will give them a try, but i am happy with the sound for now, really amazing.

I've emailed both Avlex (US Distributer for Superlux) as well as Superlux in Taiwan. No response yet from Superlux, but Avlex did respond and stated that there are no plans to bring the HD662-EVO to the US. Damn! Hi, well you've already ordered yours, but a good option is wait until someone from Aliexpress starts sellings it, it's pretty easy to find most of Superlux products there.

I got these a couple of days ago and I couldn't really have lived with the sound at all.
Changed the pads (and glad I read the thread because I had just pulled them over and let go. They held well but certainly look a lot better with the retainer band 'tucked in'.
My pair also had the extra felt pads but pulled them off, a fairly strong glue but none had damaged anything. Looked exactly like Frans picture of the internals with them gone.
The transformation after the mods is far above any other phones I've modded in the past (those not involving a Kameleon that is).
I would put them as second only to the HE6 amongst my 'phones as although not accurate they're great how they bring in great bass from realtively low volume.
Ian, where did you get your cable? It sounds like it would be the final touch for these.

Once modified they sound much better than all the other Superlux headphones.
I suspect (still need to buy a production model) that toiletpaper yields better results than the thick felt.
The cable is too microphonic (which annoys me) so I made a small extension cord from supple silicone wire. This 'isolates' the mechanical sound conductance.
Would also be interested in the link to that cable.'Might buy a few of those if they are really soft.

The cable has nice plugs and is quite rubbery. I got two. A one metre and a two metre, which gives me 1, 2 or 3 metre lengths. One metre is great for mobile, two in a chair from an amp and 3 for watching tv. www.amazon.co.uk/gp/product/B00B3UAP5Q/ref=oh_aui_search_detailpage?ie=UTF8&psc=1Syd, I agree about the mods. I think the mids are a little strange if you jump from something with more present middle. I think the Superlux might sound a bit more 'distant' but I could live with it in stock form, once my head adjusts. Perhaps, as Frans has suggested, it's a kind of 'colouration' in the mids because from the graph, the mids should really be in your face!! I suspect that with that felt removed, they might be extremely piercing. I never compared on/off. It takes a fight to get it off though!! My Sony MDR1 sounded more 'natural' than a stock hd662.

I was going to suggest the Fisual if the one you had was different. Have one myself and really quite supple and rubbery (but not tacky) as you say Ian.
Pity they hadn't opted for a 3.5mm female connection though as that would have offered up a load of options. One of the V-Moda cables would have worked a treat.

The only thing about that connection is that it is actually a good 'safety' thing when you're moving around with them on your head. Because it has that short bit of lead from the cup, it lets the cable disconnect quite easily if it gets hooked up.
It wouldn't have taken much to put a female connection there though allowing more easy options for cables.
Funny thing, in stock form, some recordings sounded fantastic and others horrible and 'tinny'. Really depended quite a lot on the recording.

Do you find them more consistent (or perhaps forgiving is a better word?) in their handling once modded? Hopefully everything then sounds fantastic!

They're less 'cruel' perhaps to bad recordings, but it still shows Mark. Flatter response headphones don't 'massage' the bass or ease the treble. They can be unflattering I think, which is why some prefer what they might call more musical headphones.
I heard a slight difference in mid tonality, I think after modding. The mids became a bit more natural for me. Treble can be adjusted more easily with the amount of tissue or whatever you use, but I opted to use coffee filters which takes it down quite a lot. It sounds more natural after mods and less boom/tizzy.
Before mods, it sounds fine. Some might not like it, but I found the bass slightly disconnected from the rest, the mids a bit strange tonally and the top too fierce. I could still happily use it this way though.
The worst thing about the mods is fighting to get the pads on. For those that don't want to ask ..... One way to do it is to stretch the backing right over the cup and then on one edge, pull the pad away until the rubber backing is close to the recess and push it in with your thumb nail. Once a bit is in, you can work your way around using your thumb nail to push it into the groove. It's a bit annoying!!
I don't mind the pleather pads either because, once modded, the mids seem better placed and the bass is quite a bit more potent, making the top seem more balanced as a result. With velour, I feel the need to reduce the top a lot but not so much with pleather. You also are more aware of just how deep the bass goes. I think they also have a slightly larger opening for the ears.... Or maybe that's just mine? Downside is that they are sweatier in hot weather.
The Sony MDR1 is far from flat, but it just sounds really good with music. It plants its own signature in quite a strong way over everything that it plays, but it's pleasant. Flatter ones are more reliant on quality of source I think. It's a more controlled sound when modded as far as the Superlux goes I think. Trouble is, you can't compare directly!! Should have bought two of them....
Unmodded, you can be very aware of the top so if you get a recording with less bass content captured, the top dominates. Modded, you still get less bass, but the top doesn't hurt as much. I treated mine to Aeropress coffee filters.
I still prefer my T50 though but we are talking three times the price plus those pads that I think are fantastic.

Received mine today. I haven't made any mods yet. My only concerns so far are the pads and clamping force. I am sure the clamping force will relax over time, but the pads are not very good. They feel like grado pads - very itchy and sitting on the ear. My other headphones (Paradox/T50, HD580, & K701), the pad does not touch my ears.
I'll give it a few days, but may have to let these go.

I never thought about the velour. I felt that mine were soft. I wonder whether a wash in conditioner might soften how they feel? There must be an alternative.

Worth a try. I washed my HM5 velour pads with fabric softener and it did help the somewhat itchy/scratchiness (and it made them smell purty)

I couldn't do that. I'd spend more time smelling the pads than wearing them....and when it comes to weird fetishes I draw the line at amp sniffing
