Sennheiser HD650 - right speaker producing lower volume. Any ideas?

post #1 of 5
Thread Starter 

It's been a long time since I've posted here last! I've been having some issues with my Sennheiser HD650s, particularly with the right speaker. I'm not sure when the problem started, and they're two years or more out of warranty, so I'm honestly not sure what to do. I've pulled out the cable (being removable and all) and the plug looks fine and secure. 

 

Has this happened to anyone else? Is there anything that I can do outside of sending them to Senn for a $160 repair? Any help would be tremendously appreciated!

The first thing to try is vacuuming out the foam.  This might remove any trapped debris like a hair that may be limiting the motion of the thin driver.

 

The next thing is to check that no digital setting such as an EQ is on creating the imbalance.  There are a few settings in the audio manager for most Windows machines that can do this as well as many other third party EQ.

 

Can you describe your setup so we can help diagnose any further problems?

 

Amp

DAC

Cables

Source ( PC, iPod, etc )

Connectors ( adapters )

 

Do you hear it on every track?

try to test with white/pink noise and swap the L/R RCA cable. Most of the time it was the amp/dac which causing the problem.

Thanks for the responses!

 

I was able to go back and test my headphones with another amp, and, after that, with the cables switched, yet the problem remained. In the end I decided to risk it, and opened up the case to see if I could find the issue. What I found was surprising: the speaker piece (which directly connects to the cable) was no longer properly seated in the enclosure. After pressing it back into place, I reassembled the casing and tried them again. Thankfully, that fixed the issue, and I'm now very glad to say that these headphones are working perfectly.

 

Pretty weird situation, and I'm not sure how the piece freed itself, but at least everything worked out well in the end. Hopefully this helps anyone else who may run into a similar problem!

YAY!

 

The HD650 is well built so taking it apart carefully is rarely an issue.
