Probably just tight at first because of that tapered ridge in the joint that seats itself when they are screwed together.

 

Good luck. It's most likely just tight from the factory. That's a good thing.

well it could be tiny piece of debris of anything. maybe you could blow into the cups and shake them. I think there is a piece of foam between the pads and the driver you can take out to expose the driver. But i don't know if this works on the 662

just try blowing into them, if it doesn't work then I would probably just replace them.

Does anyone think Superlux might get sued for blatantly using other brands designs? Almost all of Superlux full sized headphones look identical to AKG/beyerdynamic designs (super-obvious copies of the AKG 240 and beyerdynamic dt770)

 

I'm not complaining though. They are built well and they sound good too. 

 

 

Unless, Superlux did get permission. In that case good for them!

From my understanding, it's really difficult to sue in China for copying, just ask BMW.

Patents & Copyrights do not seem to mix well with Communism. 

I doubt Superlux has permission from AKG or Beyerdynamic, otherwise I would think Superlux would be sold all over the U.S.A.

Yes. I have those. They are a huge improvement over the stock pads and are a bit deeper too!

Sfwalcer, thanks for the info on the sock mod. It made my crumbling stock hd662 pads much more comfortable.

Christoffr, if you are still having problems opening up the headphone, I suggest giving a little harder of a tug. The first time that I opened them up, I was afraid of braking them myself, but after I realized how much force was required to get them opened, I could open them back up anytime I needed easily, and with confidence. The hard part is getting it back on :P You have to catch the plastic of the sup on the inside of the white (or red) plastic ring, then press them on as far as you can. The sup will have some area that won't want to fit into the ring. That part will have to be pushed in while pressing the ring on. It takes some effort, but it is hardest the first time, after that, you get used to it. Also, when putting the ring back on, make sure to line up the holes for the screws. It is a pain if you realize that the holes aren't lined up, and it won't twist into position, and have to take the ring off again to put it on in the proper place.

Nick n, I am glad to have finally found some pictures of the Sound Blaster pads on a pair of Superlux. I have been putting off buying a new pair of pads for months. Now that the stock ones are crumbling, I guess that I am forced to make the purchase. I will do that when I have a few bucks to spend. Anyway, your post about the mods you did to your hd662f isn't very clear. I was actually kind of lost when reading it. Would you mind explaining it a little better? If not, that is alright. I am pretty happy with the current sound of my 662f.

Sorry for posting here so much but.

 

 

Has anyone noticed that Superlux slightly changed the design of the 681? The older ones have bright red rings and 'studio monitor' written in small bold white font on the cups. But the newer ones have a darker more maroon red and the text on the cups says "Professional Monitor" in giant black font.

 

"Old" 681

 

"New" 681

 

 

 

The ones I have are the 'new' ones but I'm hoping when I order my new pair that it might be the 'old' one. 

 

I sort of like the new ones more because the bright red on the old ones looks cheap and tacky

post #405 of 987

Is there any difference in sound or is it just aesthetics?

 

 

Sure I can clear up the rambling I did there for that mod.

 

New pads are World of Warcraft Soundblaster headset pads.

 

What I used in the innards:

 

  • Dynamat
  • Special Acoustic filler , but any thing similar should be fine like speaker filler( polyfill type of stuff )
  • Creatology Brand Self Adhesive Foam  ( ~1/8 inch thick ,available from most decent craft stores )
  • ears :)

 

I filled  inside the raised center square ( surrounding the round cup-mount raised bits ) in the cup rears with Creatology Foam as seen in the first picture

So a square of foam but missing the center circle to fit around the cup-mounts.

 

Nothing directly on that cup-mount top it looks like the driver has a hole directly in the middle of it and it vents on that cup-mount top and is secured against it by the two stock rubber spacers. limited space there too. ( I might try it )

 I guess I also could have used a bottom layer of Dynamat in the raised square area and then put the foam on top also, but I got lazy. ( I may do it still )

 

Next I cut lemon-wedged shaped pieces of Dynamat and put these around the outsides of the square area on all 4 sides, and as long as all 4 sides.

 

I stuck the Creatology Foam on top of these lemon-wedged shaped Dynamat pieces.

 

On the inside of the baffle around the driver rear there are 6 damped tuned-port holes. 3 tuned-port holes one half and 3 on the other. There is a gap between these two sets of 3 port holes on the baffle perimeter. I cut 2 tapered pieces of Dynamat to fit into these two spots making sure to not cover over any ports. About the same width as the space between the driver edge and the baffle edge.

Covered these with exact shaped Creatology Foam pieces also.

 

Next and lastly I added some Acoustic Filler to the cup insides to deal with any further resonances and help increase perceived width and space.

 I find that if there are  tuned damped ports in the baffles of a can i use Acoustic Filler in, I need to use less than i would normally if the cans had a solid baffle and no portings.

 

This is obviously due to the fact that some sound will leak through those back to your ears whereas solid baffles not so much. This contributes to the overall sound and takes the place of some damping that the Acoustic filler would otherwise have provided So this means i use less than normal amounts of filler as it is sounds muffled otherwise.

 

Just how it works and obviously you would tune to ear depending on what you use. Doesn't have to be crammed full tight, just a less packed amount will do.

 

Reassemble cups.
