And yeah, it happens regardless of source. Guess you're right and the driver is faulty somehow. frown.gif

 

Who was the seller? I got mine open box on eBay through ProAudioStar and they have the warranty. Contact the seller, they might be able to help you.

These are mine which I did myself, mainly for the convenience of getting rid of that coiled cable, I personally don't believe in wire changing the sound so I have no opinion on that.

 

 

woops double post. I'm getting them hardwired dual entry with a furutech fp-704 jack. you went through btg audio?

It was just some private seller, with no warranty at all. It's been 6 months so they're not going to take them back now ...

They sound fine so long as I don't move my head while I wear them ... so I wonder if it's a dodgy cable connection on the right hand side.

Hard wired is a great but I wanted a removable option. I did not go to Brian @ BTG he looks to do excellent and reasonably priced work though, I put the Rean Tiny xlr's sockets in myself. And that was an exercise with a story all its own... biggrin.gif

I wish I knew WHY they designed the drivers the way they did. those posts are a nightmare to deal with. total pita.

Indeed they are, liquidzoo and I both managed a broken voice coil wire recovery... Hairy times but didn't have to replace the driver. I suppose they are not made to be tinkered with, but if they just put a little bent tang piece to lock them into the plastic, it would be a lot safer to modify.

The right-hand-side driver is making a staticy distortion noise, most apparent when playing music with lots of high frequencies. This can be exacerbated by pushing the right ear-cup slightly inwards (or even just moving it about slightly) while music is playing. 

 

I've also noticed (while playing about with test tones trying to work out what was cauing the distortion) that at certain volumes, the right driver will distort and sound much louder/harsher than the left driver. The volume at which this occurs depends on the frequency of the sound being played, but it is most apparent for very low frequency sounds, e.g. 30Hz to 75Hz. When playing test tones in this frequency range, the right hand driver will distort at only modest volume levels.

 

Not even sure if the two issues are related ...

 

I've taken the driver out of the earcup checked for hairs, and found nothing.

 

Anyone got any ideas?
 


Well, if anyone is interested, it wasn't hair on the driver, but the diaphragm itself had popped out of position eek.gif

 

I decided to pull the right driver apart to see if I could find a hair deep in its bowels (I figured they were done for anyway, so what do I have to lose!) After prising the driver free of the white baffle disc, I inspected the diaphragm surface for hairs and could see what looked like a tiny sliver of copper stuck to the edge of the central dome. I tried to remove it with some scotch tape, and ended up pulling the whole diaphragm up and away from the magnet. turns out the copper I saw was actually the edge of the voice coil under the (transparent) diaphragm. The diaphragm must have been very slightly out of position, so some of the voice coil was not correctly located.

 

Anyway, I pushed it all back into what seemed to be the correct place, reassembled the driver and ... no distortions, no crackling and an improved soundstage beyersmile.png

 

It's now 1am and I've gotta be up in 5 hours, but all I want to do is listen to these headphones ...

Ah, the curse of the 1 AM DT880. Beyer owes me about a week of sleep. biggrin.gif

 

I'm glad you seem to have got your problem sorted. Hopefully it doesn't rear its ugly head again. I'd like to know how it happened in the first place (not suggesting it's anything you did wrong), so that I might be able to take precautions to avoid having the same thing happen to my pair.

I've got so much adrenaline running through me after performing headphone-surgery I'm not going to be able to sleep for a while yet !

I suspect the diaphragm has been out of position since I got them - the soundstage/imaging always felt very slightly 'off' to me, always took a few seconds for my ears to adjust when I first put them on (which was never the case with my other phones)

Everything else about them I loved, so I've stuck with them, hoping I'd adjust to them. But then this weird static distortion appeared, and then started getting worse, and I realised there was something wrong.

They now sound how I hoped they would after reading all the threads on them ... I.e. bloody spectacular biggrin.gif

So glad that my setup is at work, other wise, the misses would be quite upset with me. biggrin.gif

After my fun fixing my DT880s last night, I thought I'd share a tip for anyone else who needs to get at the inside of a DT880 driver - get a flat-head jeweller's screwdriver (I used one with a 1.4mm head.)

The driver is attached to the white paper baffle plate by three black clips - see picture below (not my driver.) These clips fit over the edge of the driver, keeping it in place. There should also be some clear glue/silicone 'sealing' these clips to the edge of the driver, presumably to allow you to detect if the driver has been removed before (I seriously doubt they are intended to secure the driver in place.)

So, to remove the driver you need to un-clip the three clips, which I found to be pretty hard work. I couldn't get any one of the clips far back enough to prise the driver out, mainly because I was restricting the amount of force I applied, not wanting to permanently damage anything.

Then I noticed three other raised bits of plastic between the clips, each with a small rectangular hole, giving access to the side of the driver (again, see picture.) I stuck a jeweller's screwdriver down one of these holes, levered it away from the driver edge and the driver immediately popped up out of the nearest clip with no effort at all. After doing the same with the other 2 holes, the driver was free. No effort, and no risk of damage to the driver/baffle. Once you're done, the driver snaps very easily back into place by hand.

 

 

Anyway, hopefully this will be of some use to someone in future ...

Hi, after some advice and opinions from fellow 880 users. I produce music with Ableton just as a hobby, bought some 880's (250) and i need a small amp. I use a 2012 macbook pro 8gb RAM SSD. 

 

Really just produce as a pass time and space is a premium so no need for a big tube amp. Would appreciate some recommendations for a small or portable amp that will power these headphones. So far the reviews are mixed on the FIIO's E9 and 10, specifically wether or not they are enough to power these headphones. Not sure what my other recommended options are - i.e what will sound pleasing with these headphones, aware they can be treble heavy.

 

budget wise, happy to spend up to a couple of hundred £ on the amp. 

 

Just in case any one mentions, i know i know.... monitors for production :) But space just does not allow right now

 

Thanks

 

A
