Re: New upcoming HD800 mod... Rabid Dawg ][ (anax 3.0)

Hello people,

Last night we had a small experiment in a small private meet. We compare a stock and my modified HD800 out of Sennheiser HDVD 800. Source is a Chord Hugo TT connected to an iPhone 6+.

For your information, my HD800 only has the shelf liner according to purr1n's recommendation. It's around 2mm thick.

Our finding is interesting. We tried to do a small blind test and there is an agreement that the modified HD800 sound more detailed than the stock unit, especially in the midrange.

I wonder whether you people feel the same thing about the modified HD800?

Regards,
Jeremiah

Well, I've always personally contended that the dust covers veil the detail on the HD800.  My own statements in that regard have fallen on deaf ears... rather no comment. I've been running stock with the Crack amp for a couple years and finally broke down and put together a mainline which was a huge improvement. I'd forgotten about removing the dust covers until now. The mainline is a real detail oriented amp but still very smooth and polite with the HD800. The mainline has potential to run nicely with the dust covers removed, but a better replacement is still required. So here I am. :)p15

I didn't find the thicker rug liner locally yet, but I did find thinner shelf liner at Wal-mart. 'Duck' branded 'Select grip' easy liner. I've also found double sided tape to adhere to the shelf liner a bit too much and if you need to replace then you're possibly cutting out new liner. I've since tried out Scotch reusable tabs. Seems to adhere to the liner and cups in place enough so far and there is no fight at all removing it. Apparently the Scotch reusable adhesive can be washed if it accumulates too much oil and starts to loose its grip.

The shape cut is a bit of a challenge. After refitting just liner and the trapezoid piece craptology foam I think its the best mix, but I'm convinced the easy liner that I'm currently using is not quite dampening the shells quite enough compared to the original dust covers.  So what I hear currently is a ton of space and detail and the trapezoid is doing thing. Its all a bit on the hot side. A lot of my inner metal ring that holds the driver in place is exposed. I believe that is also contributing to the hard effect I'm still hearing. With the craptology ring it was over-damped.

I'm thinking to use the current ring pattern to cut a layer of shelf(rug when I find it) liner to get that covered properly since exposed it definitely adds to the 'hard' nature of when you have the headphone running without the dust cover. I'm planning to that cut ring and bond it to the my existing liner using double sided tape for a permanent bond. I hope the result will be a dust cover shaped section of liner that fits in like the original.  I'll report back how that works when I have time to get to it.

Definitely have to find the rug liner. The easy grip shelf liner better than no dust cover, but its not cutting it.

I've been using the HD800s without dust covers for some time now. Several of my friends also confirmed that it "unveils" the HD800s in terms of detail/clarity, and never looked back since. As heard on my EC no headphones I've heard so far quite match the HD800s in terms of macro-detail. Add some Yggdrasil to that, and this sh** is not for the faint-hearted.

I only use the rug liner and no dust covers. For the rug liner to fit better, I've cut half way through 6 points around the corners so it folds better inside. That's it and this is the best I've found so far. Credit to lojay for some of his suggestions.

I'm a bit embarrassed but I have to admit than I just discovered my hd800 sounds better without the dust covers. Clarity and resolution have improved. It's time for me to try the mod now. The brightness improved a bit as well.

Well I didn't cut em up, but I did make heavier rug grip rings same size as the metal driver surrounds. They are adhered with .5x.5cm scotch reusable squares about 1.5 cm apart to add to the dampening to the ring. The heavier rug material wins over the  thinner slight margin for total cohesion. I've either in either ear right now, so its a bit weird.

But getting it right with the trapezoid and the metal driver surround appears to be critical. I'm totally floored right now. Haha. No pun intended.

Hi people,

Is it safe using the HD800 without the dust cover? Would not oil, dust and fine hairs get into the driver?

Jeremiah

Sennheiser put some panty hose in front of the driver to prevent that. Stuff does get attracted there if you keep the covers off so I use my record brush to pull that crap off.

Yup, with the dust cover off, the driver is still protected by it's primary cover/grill assembly. The dust cover is secondary for protection.

Also for dust, use a low tack tape like you would a lint remover. Use a few gentle dabs:



Glad you guys were able to do a BT to confirm. I've been advocating this for ages and it's integral to the mod. Now if you have speakers at home, try removing the grill covers and have a listen.  ;)
