Opening a Sennheiser HD570 for repair

I have a pair of Sennheiser HD-570 headphones, which I love, but they recently lost sound on the right side.

I thought, like anyone, that the 3m cable needed replacement, I bought a new cable and foam for the head piece from Amazon only to find that the right side was still dead.

I searched the internet for information on how to take apart the hearpiece to get to the speaker piece but to no avail. I had focused on getting to the speaker from the inside because the external part is so solid, but i have today found the right way to get into the spearker. Only to find that the plug had fallen out !!! 

The cable can drop out of the plug on a HD570!
A very simple fix if you get in.



Attack from below with small object

 The bottom is a simple click tab

The upper part is more of a 90 degree tab.

I used a flat screw driver head and force

Take care of the head bar location because the cover is so large.
Start by clicking off the bottom

 Open up the head part and click the top part of the external cover

Move the head bar back to taking of the cover piece.


Become shocked to find that the cable has just dropped out of connection!
(THIS IS HOW I FOUND IT WHEN I OPENED!)
Close up on the fastening points of the outer piece, so you can see how much violence you are allowed to use ;)

Put the cable back where is belongs and cover back on... and done!

The pads do get worn, but you can still buy replacement pads from Amazon, cheaper than replacing the headset.

The sound in my Sennheiser HD570 is still great after 15+ years of service.
