I've got an older pair of Sennheissers with a speaker out. Dropped on the floor one too many times. Maybe a broken solder joint? Need some advice - be a shame to send them back to Sennheisser for repair for a problem I might be able to fix in a few minutes.

Oh yeah, I need instructions on opening these puppies up too. Looks like they could have been designed to keep the owner from getting in there and trying to do their own work.

Could be the plug or strain relief. Can you wiggle the cord at either end and get any response? Phones are simple, should be able to diagnose once you get them apart. What model?

HD 545

The cable is replaceable on these (and apparently that's a good mod). I swapped the ends around and the bad side stayed bad and the good side still worked.

It appears that the cable connector in the earpiece is a weak point on Sennheisser headphones, most likely that's where my problem is.

Does anyone know how to disassemble a pair of HD495's? My brother managed to break his pair and it seems the problem is in the connector (the cable is fine). From what I can see, the earcup can be disassebled, but I am a little unsure of who much force it will tolerate without breaking. Are there any tricks I should know about here?

Quote :
Don't have those myself but are they not typical?

I mean, snap-off pads, screws under that, and a clip inside on the cord's strain relief piece?

If you are needing to subject it to stress to disassemble, heating the plastic a "little" should make it more flexible, less subject to cracking but I wouldn't think you'd need to do that.

I had posted a few posts down about the faulty cable connection. I read somewhere that someone disassembled the headphones and tightened up the springs that connect to the cables. I was wondering if anyone knows how to disassemble the headphone? I figured out how to get the velvet foams off by just plucking them out. But it doesn't appear that the plastic layer underneath it can just be plucked out. Seems to be locked in somehow. Any ideas? Thanks for any help!

Now I've just got to figure out how to open them up.

This might help (these are HD 650s). Looks like a bayonet style system. Try turning the speaker clock-wise in its case. Might as well add some rope caulk while you're in there.

Interesting - unfortunately 545's have an oval housing. headbutt Twisting won't work.

Thanks for the suggestion.

They've got to come apart somehow, but I haven't even got the velour part off yet.

The housing may be oval, but are the drivers? I could still see the bayonet system as an option. Wouldn't hurt to try.

Maybe try removing the ear pads - they usually slip off. Is there any clues underneath?

Another option, if the housing has "reveal" gaps, like door gaps, it may be a snap together assembly. Try inserting a small flat screwdriver in the gap and gently pry outward from the center.

i did a little research on this issue, it looks like you can replace the whole cable but you already said if you could fix it for cheap thats what you wanted to do. i scanned google for a bit and found this thread:
http://www.head-fi.org/forum/thread/86786/sennheiser-hd545-vs-hd580

you can read all of it, but there is a post about half way down the page by "bill ward" that says that the problem isnt the cable, but the connector. another post a bit after that by "pp312" confirms that this is what happens with the hd 545's and if you spray a bit of "craig pro gold" on the male end and insert it a few times and repeat, that it will help the connection.
i searched for the pro gold and the name has been changed to DeoxIT gold, heres a link to what it looks like:

hope that helps!

I got the muff off -

Repairing headphones? Hd545_01

Where to go from here? The speaker is mounted on a plastic piece that rocks on these center pivots -

Repairing headphones? Hd545_02

I'm at a loss how to go further.

97 park ave - I guess that could be it - my gut tells me there's a problem inside somewhere.
