HD600 sprung back to life with a kiss of youth? A great fix.
« on: February 21, 2020, 05:07:35 PM »
Anyone who has owned the same pair of HD600 for a couple years probably knows the problem.  Intermittent contact with the capsules.  Sounds like a broken cable or connector.  You move,  crackle. Annoying.  Even scary at higher levels. 
New cables donít really help or do sometimes for a short while until the somewhat bent contact springs settle.  Then itís back to crackle crackle. 

I decided to google again and see if I could find a fix.   I ended up watching a YouTube disassembly of the HD600 by inner fidelity.

To my amazement he showed that the springs are a Sennie spare part and replaceable. 

They push in and out with some care. 

I ordered the only  4 springs in stock with Sennie SA.   
Got them picked up.  Courier cost more than springs.   

Ready to rock and roll I got stumped a little.  My wires were soldered on to the springs.  My HD600 werenít bought new and are old.  Maybe they are real early or even got ďmoddedĒ.  Dunno. 

Anyways.  Nervous as hell I proceeded.  The lead wires are as thin as those on a cartridge coil.  Low temp.  Magnification. Facing Mecca and holding breath I managed to desolder a spring at a time and fit new springs one at a time and solder the leads to the new springs which are an easier to solder material than the old ones. 

It worked.  I broke bought.  No more crackle.   With the fresh sushi is from a few months ago itís like a an old friend who got a boob job and some Botox.  Lovely again. 


Very pleased.  My best hifi spend of 40 bucks plus vat for 2020.

Good job! What a pleasure to now be able to crank them up without fear of permanent hearing damage!

My own HD600 must be pushing 10 years old and (touch wood) look and sound as new, although pads, cable and headband pad were all replaced about 2 years ago. Original spares all bought at Mitech. Love the fact that I can do that...

Great find Croak! My 600 and 650 is fine but I have a pair of HD540 Reference Golds that has the Sennheiser jiggle. Wonder of those springs are compatible?

Dunno.
I wanted to get some more for a friend but now am told no more stock and canít order anymore.  Strange.  Anyways they are showing available abroad. 

I have asked for them to check under the 650 parts.

It looks like these are out of stock in several places abroad to.  Full compass have stock it seems. 


I think likely the same as 540.  My google searches turned up compatibility with 545.

I prefer the original version, allows for more imaginative flair.

Sennheiser SA but there is no more stock and apparently obsolete ex Germany.  I got the last local 4 pieces it seems. 


There seems to be stock at this vendor abroad.  I have a friend interested and I think Scubadude on here may be.  Perhaps you guys can do a group import.
