Up next - WOOOOOD! You dirty beast. It's only a headphone.  Here`s a teaser of my HD-662F wood re-design (HD681 wood version to come in future):  This is only a test version and needs lots fine-tuning with internal filter/filling materials probably but hope the result will be good  Pads will be Olive-green velvet filled with air-tight neoprene. Oak will be "blackened" with ammonium and oiled with teak oil. |

Btw, is there any UK member here who has done a lot of cans tuning and modding by adding different dampening and filtering materials etc. that someone can recommend to contact? I`m actually thinking about sending one wooden HD-681 version to test and tune to someone.
Maybe if I get this wood version "right" I could start making them in small orders. But this is big maybe. Depends how material supply, time, machinery and price etc. turns out.

That's some impressive word  wood working there! Can't wait to see it polished up and rebuilt, they'll certainly look SuperLux-ery. |

Hi guys,
I've just bought a pair of HD681s (for the ridiculous price of £18.50) after reading about them here, and have already ordered a set of velour pads to replace the factory ones. I imagine I'll rewire these as soon as they arrive too. I plan on mostly using them for playing guitar through, so I'll probably go for somewhere around 3-4 metres. How have people gone about wiring to both sides? I'm not sure how the split would work...
I'll be comparing these to my Sony MDR-1Rs that retail for about £200 now, but I'm hoping the HD681 will blow them away, especially after some modding!
Martyn
PS. I'm also in the UK, and quite handy with a soldering iron, so if anyone from over here is struggling getting anything sorted on these, give me a shout, I may be able to help out!

Hello there, I'm totally new here and registred especially for this thread. I bought myself a HD681 B, a few months back, but the excess highs got on my nerves. So I've had an electronics specialist done the filter that Frans put on this thread. For €13 my HD681 B has now transformed into well balanced headphones. Just wanted to let you all know this threat keeps inspiring people.  |

Depends if I got something to say/read around here Something to say would be good! A forum is only good if many people contribute their thoughts / ideas to it...... if it's full of "readers" the posters (to the masses) tend to burn out..... fresh blood / new ideas are always required.... feel free to let rip with your thoughts and ideas (on any subject)...... evolution is the general way to go with audio devices but a degree of "revolution" is required when it comes to forums..... we all come here to read other's opinions but very few go the extra mile and lay down their OWN opinions...... we have thousands of "readers" but could do with a few more writers All the best, Mike. |

hello!!! i'm new here and and i want to know where can i find helliharris ring's? see you joska from france There were only a limited number made, and they are no longer available. Alex They didn't do a lot to the SQ (in all honesty) but they were very well made and enhanced the appearance of the 681..... The "Two pence" mod actually improved the SQ but it looked a bit daft with two "two pence coins" glued onto the housings  Only "Four" pence for the mods though so if you don't mind what your phones look like then 2 x two pence (British coins) are a perfect fit...... I can supply acoustically treated 2 pence coins for £395 GBP each (only joking!!!) a bit of butyl rubber tape damping inside helps to tame the highs and get rid of those nasty "pleather" pads..... the velour ones are a lot more comfy and also improve the SQ by quite some margin. There's a guy who sells "filters" but if the 'phones are that bad to your ears just dump them or use a (nasty word) equaliser to tune them to your preferences. I actually preferred the "stock" sound over the filtered sound..... either I'm going deaf or that bloke with the filters has gone deaf..... I dunno, I prefer the stock sound..... I'm 52 now and don't want to "tame" frequencies..... I want them boosted! Give me a loudness button and I'll press it Mike. |

I ordered original Superlux velvet earpads for my HD681 B yesterday, I'm curious if they are better the the expensive (fake) AKG pads I bought at Thomann when I ordered the Superlux with them. The, so called, AKG pads have a smaller opening and therefore don 't really go around my ears. Don 't like that. And I will do some writing soon, bought headphones from another Chinese brand which I like very much.  |

I'm 52 now and don't want to "tame" frequencies..... I want them boosted! Give me a loudness button and I'll press it Mike. I've never found the need to filter these phones... I nearly made up some filters, just for something to do, but couldn't get started on it because my particular pair sound just fine. Innerfidelity.com said they were like listening through razor blades... bright when straight out the box, yes. But not now, not at all. At this price point I'm guessing that there'll be plenty of variation between individual pairs of 681s. Maybe I have a lucky pair? The only thing that still really annoys me is the resonance of the metal hoops in the headband. I saw one review where this was mentioned, but in here no-one else was bothered. Guess it's just me then. BTW I think the 681s are not robust enough for the rough and tumble of family life. Both of my son's pairs have lost sound in one earpiece and they have young kids. The one's in 'Grandad's House' are still in good nick I would not have discovered the 681 if I wasn't in Grotto. I mentioned how good I thought they were in another forum I enjoy and the reponse from one member was basically "Have you SEEN the frequency response?" ! I don't think anyone really understands what a 'good' headphone FR looks like, hence all the different voicings we see on everything from 10 dollar earbuds to top-end Stax's. (Always had a soft spot for Stax... maybe one day). And it's odd how enthusiasts will excuse some really inaccurate FRs when it comes to MC cartridges... peaks of 6dB at 10 kHz? Come ON, get a grip. And then if you have a passive pre-amp that a half dB DOWN FFS.. well the whole world is in anguish. Derek |

The stock sound of mine was unbearable, like needles trying to penetrate my brain. Maybe I'm treble-shy but I hated it. Frans' filter made these HD681-B very balanced, almost as my AKG K271 Studio. But then at 1/5th of the price ! But balanced doesn't mean they are fun, they too analytical to be fun. But being "studio monitors" I don't mind them being analytical, for the fun factor I'll use my Somic  |

The stock sound of mine was unbearable, like needles trying to penetrate my brain. Maybe I'm treble-shy but I hated it. People's experience of the 681s seems to be so variable doesn't it? I've been a hi-fi lover since goodness knows when and I reckon I could listen to headphones or speakers and say if they were 'bright', 'hard', 'dull' or whatever and be confident that most people would agree. So what's going on with the 681s? I would call them attractively bright... I'm going to have a good listen to mine tomorrow to make sure I haven't mis-remembered their character. If I have then I'll 'put my hands up'. Been doing a bit of very amateur recording recently (in this case, my rendering of Sinatra's 'Wee Small Hours') and the 681s are great for monitoring during recording. Derek P.S. I have no idea if my 681s are A, B, C or what. |

What color are your rings ? Red = plain, grey could be B or F.
I have Sony MDR CD570's and that one has a enormous brightness over it which totally brings out much detail. The Sony's highs sound very musical and it doesn't disrupt the songs I listen to. The Superlux, on the other hand, made (without filter) every song sound bad. Like the most boosted freq was one where all the rubbish was heard.

The Sony's highs sound very musical and it doesn't disrupt the songs I listen to. The Superlux, on the other hand, made (without filter) every song sound bad. Like the most boosted freq was one where all the rubbish was heard. My 681s are finished with red rings. Later today I will hook them up to my main system but last night I spent maybe an hour with them listening to both Classic FM and BBC Radio 3. This was on my bedside 'system' of a Pure DAB Radio using line-out into my V-CANii. DAB radio isn't famous for having a smooth and delicte top end! But the top end was good. My main negative crticism would be that the upper bass / lower mid is coloured, congested a bit and as a result the music is not as open and free from the earpices as I'd ideally like. Bass on lower string etc satisfyingly full, but not particularly extended. But overall, for a 20 quid pair of closed back 'phones? Musically satisfying enough. But no irritating top end emphasis in my pair of 'luxes. The HD 661s on the other hand.. your description of the 681 matches my impression of the 661... I could not enjoy the 661. Listening right now to BBC R4 news on my DAB/V-CANii.. spoken voice very well balanced with just a bit of lower 'mid bark'. It would be great to be able to get together, us HD681 users, and see how much they vary. Or are they particularly system-sensitive? |

Am intrigeud with how people react si differently to the character of the 681s top end. I looked at the original 681 thread started by Mike (Pink Floyd) and here are a few quotes:
"The bass was a little sloppy and the mids and highs a little recesssed"
"when run in Bags of energy, Good detail, excellent soundstage, warm mids, tight punchy bass without being over the top and detailed highs"
"the sound was lush and warm but still with plenty of detail. Any harshness the cans had (which was not a lot) has gone"
"with my mp3 player... they sounded a bit shrill"
".. (the HD681s are) something between my laidback and dark sounding Senn HD600s and my bright and aggressive Grado SR-80s"
And my first comment when straight out of the box: "Sound balance is revealing without being too hard; an analytical listening experience I'd say; if recorded vocals have been EQ'd to give them some bite and presence you will hear that EQ as being a bit false... I played one of my own vocal recordings made with no EQ and the sound is so smooth - yet properly detailed.
So some of us perceive their sound as shrill, like needles... etc. And others say otherwise.
Currently listening to orchestral music again via DAB/V-CAN and strings are lush, bass solid. I'm not hearing so much of the coloured upper bass lower mid that I got last night. It's there still but it's no big thing.
I can't see why it was thought that the 681s needed that notch filter add-on. But each to his own.

I've got the filter Frans designed in it now and I am amazed how good these are now. If they were closed they would be as good in the studio as my K271 Studio. Okay, the sound isn't playfull, but it is fairly neutral now. One of these days the velours Superlux pads will be delivered and then I will really know their full potential.

Here we go, the velvet earpads are in tha house !!  These are quite different from the AKG earpads I got from Thomann. These are softer, more comfy, the hole for my ears are bigger, better made and a lot cheaper (€10 instead of €17) Suddenly my El Cheapo Superlux has almost DT770 pro-ish comfort. Bass seems a bit tighter too and highs seem to be softer. Maybe just something to do with the dampening of the velours. I love 'm |

For those who haven`t read Superlux HD-681 - revisited (mk3 filter):
Useful info about using different pads on HD-681 & filters for low-ohmic/high-ohmic amplifiers.

If anybody requires further information, I suggest that they send you a PM for the link.
The other forum concerned censors mention of Rock Grotto in their threads when mentioned.
Yes, I agree it's rather childish, but we didn't start the precedent.
For my part, if somebody asks in a thread how to contact the designer, I send them a PM with the appropriate email contact address,
rather than ignore the request.
Alex,

Sorry, didn`t know there were issues with that ;S Just thought it might help someone and since Frans is active also in this forum
( or he isn`t anymore? ) I thought it would be ok.

welcome to the forum, hope you stay round 
Only "Four" pence for the mods though so if you don't mind what your phones look like then 2 x two pence (British coins) are a perfect fit...... I can supply acoustically treated 2 pence coins for £395 GBP each (only joking!!!) a bit of butyl rubber tape damping inside helps to tame the highs and get rid of those nasty "pleather" pads..... the velour ones are a lot more comfy and also improve the SQ by quite some margin. There's a guy who sells "filters" but if the 'phones are that bad to your ears just dump them or use a (nasty word) equaliser to tune them to your preferences.
