picasaweb.google.com/clausnn/ATHW1000#5426724956471942530before and after. They isolate very well, the bass is more thumping/dry the distance to the driver is longer which gives it a tiny bit more air, but the isolation is making it sound more like a closed phone, strange thing wider and narrower at the same time..  Now I really need the red Cable, how did you make the wires go from left cup to the right ? I would hate to use the rods in the headband

Not surprised to here that Mike, its called production runs, no matter how tight the tolerances are, be it Headphones, upgraded rings, ballbearings, F1 engines, Rolex`s, Cameras, infact anything thats engineered, there will always be a certain percentage that dose not make the grade, and unless each individual component in a completed unit, was tried and tested before leaving the factory, some sub- standard units will slip through to the customer.
On a £15 set of Headphones, i would expect possibly 1 in 250 to be properly inspected and tested, £200 set 1 in 10, and £1000 set, probably each one. The expectation of a £15 set of Headphones sounding great would be low to most people on purchase anyway, the fact that they sound great, and a very high percentage WILL sound great, is enough to justify Superlux`s build quality to cost ratio, so expect there to be some sets out there, below standard.

Claus,
Just out of interest. Did you actually cut and restitch to get the larger aperture?

Claus, Just out of interest. Did you actually cut and restitch to get the larger aperture? no no not at all just plain old violence, first give them a tinsyvinsy bit of oil when they are dry, you just work it down on something cone shaped, I used my manhood. Then let them sit for some hours and massage the hell out of them while they are sitting on the "cone", this gives the inside of the padding another profile and helps keeping the shape over time. Ans also feels quite nice  You can make them very stiff and force them to keep their shape, but I fear it would kill the comfort, so I made it softcore and it might need a stretch from time to time, but rather that than a hard edge.. |

Mick, BTW.... your recabled HD-681 are on the way to you.... I fitted black Evolution Pro cable, it's less tarty looking than the red Thanks Mike, you have a PM.  |

Here's a Pic of my Solderdude/Heliharris mods pair. The AKG pads make the difference between wearable and head boiling! Mike, your remarks on QC variation maybe explains why I was a bit disappointed with my first pair, though they were nowhere near as bad as you encountered.  |

massage the hell out of them while they are sitting on the "cone", Do I really want to put these on my ears? What about the outer edge, is it still a tight fit arond the 'phones? |

The outer edge is not affected, it even fits a bit better, now they stay on. The comfort is also better, my ears do not touch the drivers anymore. How big a hole do you need ?? within reason they can get even bigger 65mm maybe even 70 mm.. I am also not sure I like the thougth about rubbing my groin up against a bald scotsman. |

Syd, They look quite the part will the velour pads and ali rings don't they? I was very interested in your view on SQ with the taking the best from 701's and 650's, after the filter was implemented. It gives a pretty good idea of what they should sound like. Interestingly enough, I've read people saying that's how the HD800 sound. |

Hi Will,
That's exactly what my conclusions were when I heard them side by side.
I guess no one believes me... but they will.. after the mod has gone in a few of these cans and some of the members had the chance to hear them side by side.
Again I am not saying the HD681 modded can match the performance and build of the HD800 but it comes ridiculously close and has nearly the same SQ ... except the HD681 has deeper bass.
But is NOT a dark sounding headphone at all.
Like I said it sounds just like the HD800 but with more/deeper bass.

Cant wait to get the filter mod onto my play pair!
I have two pairs now as the wife was wanting to borrow them all the time.........
So one standard and one modded, sounds about right.

Hi Frans,
You're comment on the hd800 earlier in the thread did catch my eye. I haven't heard the HD800, but of the more reliable accounts of people who have do mention the HD800 sounding like a K701, but with 'more' too it. The fact you have heard them and the filter-modified hd681 sounds similar, is very interesting.
Whats happening here with the HD681 reminds me of the Jaycar SCHA. In stock form, they are good, but modify them, and you get something much, much better. It really shows how DIY can really get you something special.

I don't wat you having to stress your "cone" to 70mm proportions Just rub a 60mm hole out for me please.... many thanks. Mike. |

I'm having a think about the best way to make an "offline" filter for the HD-681..... It will be along these lines:  Probably without the cable inbetween with the filter located between the jack plug and line socket.... just a case of finding the neatest way to do it. Soooo..... if you fancy a bit of filtering you just plug this device into your amp and then plug your 'phones into the device.... gives you the best of both world's (filtered / unfiltered)...... Should be easy enough to do and could always be expanded on by keen modders.... ie: you could build several different values of filters into a box and run them through a suitable switch so you could "tune" any pair of headphones at the flick of a switch.... this would obviously be a more complex affair than the simple inline filter but would be fun to try  |

Hi Mick, my first 2 filters were made in a piece of plastic electro piping (don't know the exact English word), the yellow or grey plastic piping where the wires in a house run through). You solder the parts in free air between 2 pieces of wire that connect to a male and female connector (be it 6.3 or 3.5mm). make it so the whole an slide into the small pipe/tube. When it is in fill both ends with glue or silicone and let it dry. To make it look nice I added shrink-tube around it. Voila.. ALL standard HD681's have TOO much highs and really should have this filter fitted permanently in order to sound exceptionally good on any recording instead of just very good. With the filter installed you don't ever want to go back to living without it. The filter is not meant just for 'occasional use' if you feel like it would give improvement on some recordings. It is there to correct a (not very disturbing) flaw permanently. Almost everyone mods his cans permanently with damping materials, holes, pads, wiring e.t.c. and this mod also is kind of mandatory permanently installed to make it shine even more. As you always say mike: there is no such thing as a can for every kind of music. Where the HD681 didn't do well before the mod there will be more kinds of music where it now is capable of sounding very good and STILL can play the music (even better) where you thought it was already good. You'll see yourself grasping for other cans a bit less with the mod permanently installed. If you were going to make a box for correcting different cans you might want to think about a box in the line circuit (before the HP amp) and be doing digital filtering or analog but in any case you will have to make a lot of (technically based) filters. And I was thinking at these forums they didn't like filters.. Have filters for HD650 (veil lifter)  and DT770 (which has over the top treble, just like the HD681. The bass of the DT770 must be made tighter and has to be done with non electronic measures. PM me for the original pdf files if interested. Don't overdo mods as the cans will start to sound somewhat like an AKG K-701 detailed but a bit boring (sorry for that K-701 fans, just my opinion) |

After cracking open Mick's fresh pair of HD-681 I cracked open another pair all ready for the Fran's filter mods and was SHOCKED when I listened to them (fresh from the packaging)..... they were VERY sibilant and screechy, nothing like the stock HD-681 I am used to (I have heard about 9 pairs now) but just shows that variations between batches do exist. One of the new members on here (Covenant) has been wondering what all the fuss was about with these 'phones as he has had the same experience with harshness and sibilance. I have been running a pair in to send to him so that he can hear a "proper" pair. I hadn't got around to trying them with my modded X-CansV2. Blimey what a great combination. Sounds absoutely stunning IMO. I tried them with the Blue Banzai (which sounds great with the Senn 595's) but there was no contest. In comparison the Banzai made them sound very shut in. Just shows you, you have to choose a 'phone and amp carefully. |

Here we have some mods kindly sent to me by Frans de Gruijter of The Netherlands (thanks Frans!) They come complete with very good instructions / blow by blow pictures and a schematic of his filter circuit. I haven't tried them yet but will definitely give them a go over the holiday period. Here they are: www.rock-grotto.co.uk/HD681.pdfwww.rock-grotto.co.uk/HD6812.pdfFeel free to add any more mods / tweaks to this thread.... I will post details of Mick's (Helliharris) alu ring tweaks here also. Mike. Can anyone confirm which connectors are identified as 1, 2 & 3 in the schematic in the second link above? I am assuming that 3 is GRD, but which are L & R. Am I also right in thinking that the phone jack is IN and the phone plug is OUT. |

I dont think it matters if either 1 or 2 are left or right as the circuit will work either way. In would be the cable coming from the source (cd player) and out will be the headphone side.
If i am wrong the somone please shout

If i am wrong the somone please shout Andy It doesn't matter if the schematic is followed, however there is hard wiring to plugs and sockets here, and errors can be made. Alex |
