I really, really like my K701 and have no plans to change headphones. However, I've noticed crackling and occasional loss of sound in the left channel. The sound breaks up whenever I move that that portion of cable that goes into the phone.



The sound break-up is aggravating to the extreme. How do I most easily fix this issue? Your DIY experience is greatly appreciated.

Are you willing to open the headphones up and take a look inside them? Sounds like you have a bad solder joint, or some other form of a bad connection. It will require you to resolder the connection.

Or you could send it or get it repaired by one of the many cable builders on these boards, the AKG genius Fitz or one of the commercial builders such as Apuresound or moon audio.

I'd love to open the left side up; some solder should be able to fix the problem. But getting under the silver piece on the outside is a challenge. Even an experienced DIY'er gives warning in bold print (start at post #49).

And then there's the soldering.

Turns out it wasn't a bad solder joint, but a break in one conductor near the bottom of the strain relief.
