Also, on a sidenote, your post sounds like "I have not ever heard the E17 but I'm just going to assume more expensive amps sound better".

 

I have heard the E17. And I have also heard the DT880 600 with much better amps... so I know the difference is there.

 

Play anything with low bass and pretty much any amp less powerful than an O2 clips horribly. It's especially noticeable in movies.

 

You're mistaken if you think the Fiio E17 is enough to drive the DT880 600 to its full potential.

No one said the E17 drives the DT880/600 to their full potential... I think people need to read more carefully.

The resonance was different for each side and it seems, that on the left it has vanished after these 5 minutes. On the right side it is still there. Just only with certain notes (first bass-notes on "Spanish Harlem" and frequencies around 20-40 Hz on a test track).

Has anybody experienced the same? I read something in a German forum where one had this problem after a long time not listening to them and it disappeared over some time of usage. 

Or would you say it´s definitely defective?

Lucky that I bought used but from dealer with 14 days return policy.

But I would rather keep them as they look like new and are max. 1 year old.

What are you amping with?

Just at the moment with the Audinst HUD-MX2 with normal gain setting. Dou you think that is what causes the buzz? It is even apparent when listening at low levels (pot at 12 o´clock). At home I could doublecheck with a receiver or cd-player.

 

For one thing, I think you'd want to use the highest gain setting for a 600 ohm headphone.

 

My 880 Pro's bass changed slightly in the first 10-20 hours. Give it some time. If the problem's still there, try it out of a more powerful amplifier. If its still there, get in touch with Beyer to have the drivers replaced. I doubt it will come to that though.

I agree... The highs in my 880's also changed slightly with time (got less strident).

 

And yes, try it with other amplification... especially a good strong receiver or known DAC/AMP.

Is the Buzz in both earpieces? Certain music?

Did not found the hexagon wrench to change the gain setting at first. Now I did - problem is still there.

I would suppose it is not a burn-in problem because they are already used and it sounds more like a real problem. Sounds like small plastic jumping on the membrane and getting in resonance. Is that the way an amp sounds when clipping? I think the Audinst may not drive the 880s to perfection but should give a technical clear sound, especially as they refined the amp-section and clearly stating as usable with 600 Ohms.

Just while writing this I remembered having a SPL Monitor Controller with headphone-amp-section here in the office. Tried this - same same.

Does it make sense to search for hairs between the foam and the drivers? I guess I have to dissamble something for that.

To me that sounds like a hair stuck in the driver. I've had that happen many, many times on my 770 Premium (though its never happened on my 880, at least not so far). Its an easy fix. Remove the ear pad and pluck any hairs from it that you can see. Then use scotch tape or a lint roller to remove any hairs stuck in the cloth that is covering the driver. If that doesn't work you may need to pop open the driver. Simply insert a small screwdriver into the tabs surrounding that same plastic & cloth piece that is covering the drivers and carefully pop it out. Proceed to suck/blow any hairs out of the driver enclosure and the let us know if that fixes it.

Absolutely. My 'open box' but essentially new pair had a buzzing resonance in the right earcup when I first played them.

 

After lots of research, I took the pad off and removed the driver cover (held in place by a plastic ring that you need to prise out with a small screwdriver) and found a 1cm strand of copper stuck to the felt that covers the driver! I removed this, re-assembled and the buzzing was gone.

 

Also worth using a lint roller on the both sides of driver covers to make sure there are both stray hairs of whatever.

post #2932 of 7111

Before I came to searching for hairs it got even worse - one driver is now completely dead. So there´s obviously a serious cabling problem. Back they go. On one hand that´s a pity. What I heard besides of buzzing was what I expected after reading this whole thread and more - really impressive. So I am sad not to listen to my favourites with these cans this weekend. On the other hand I am happy that it was not the Audinst causing the problem. And what it delivered to the cans was for the intended use at office in my terms sufficient (although I´m sure there´s an amp coming for home use).

And now that I am sure to go with these cans I could order them in my favourite design:

 

Btw, I wonder why I in this hole nearly 200-pages-Thread nobody mentioned the wooden cases from Beyer.

To me it gives them a worthy look more adequate to the sound than the plastic.

Well its not actually wood.

Do you know that for sure? 

The Website says "Wurzelnussholz" - what means burr walnut wood.

That sounds to me like real wood and not coated plastic.

post #2935 of 7111

Would adding the FiiO E9 desktop app suffice? or do they need an even beefier amp? Sounds like the O2+ODAC Combo might be a good option but that's another 300 bones.

Or just get the O2 alone and pick up a L7 to get lineout from the E17. That was my previous setup before I picked up the Aune T1. Worked great for me.

I'm not sure. Do you have a link? Apparently that is different from the Manufaktur version?

 

Its most likely coated plastic and they're just referencing what kind of wood its emulating.

It is just from the Manufaktur.

You could be right as they say carbon too and these are for sure not real carbon.

That´s sad. They looked like my good old Volvo 850 interieur with real wood and real leather.

If it's Manufaktur then it's just plastic.
