Headphone balance issues

post #1 of 12
Thread Starter 
I love my HD 555. I really do, even though the right driver has been noticeably louder than the left one ever since I purchased it (used). Since I only use it at home, there has never been much of an issue; I amplified the headphones with my Kenwood receiver, being fed from my computer, and adjusted the balance on the receiver. Once I realized that adjusting the volume on the receiver threw the balance off centre, I started using digital balance control on my Mac.

The digital solution works really well. When I adjust the volume on the computer, it automatically adjusts the balance to cooperate. Even better, adjusting the volume on the receiver won't change the balance on the headphones, even though the computer is not accounting for this. It would seem that the flaw, then, is inherent in the receiver's balance adjustment circuit, not analogue balance adjustment in general.

So I'm a bit worried. Why? At some point in the far future, I can see myself buying another pair of headphones. Perhaps from Grado, perhaps from AKG, it could be another brand; the point is that I'll be using two pairs of headphones from one setup. When this happens, I won't want to go into my sound preferences every time I switch headphones, and I won't want to use the balance control on my receiver.


A solution that my mind has though of is some sort of short extension cable for my HD 555 with an inline balance control, sort of like a volume control. I'd leave this on my Sennheiser headphones, and I'd never have to worry about adjusting balance again. However, I've never heard of such a thing, and there's not much reason for it to exist.


Do any fellow Head-Fi'ers have any ideas that might be helpful? I need a method to keep the balance of one pair of headphones adjusted, but that will only affect that one pair of headphones. That way, all I need to do to switch to a different pair is to switch to that different pair. I don't mind if the solution is not exceptionally Hi-Fi; it just needs to be effortless, and pretty, if possible.

I appreciate any help!

Sounds like one of the diaphragms has a loose coil.

I assume it's not possible to DIY-fix that. How much would Sennheiser charge for a repair, or a driver replacement?

That is a question for Sennheiser service people...

Fair enough, thanks for your help

This probably won't help but have you tried taking them apart? I had the same problem a while back with my 555s so I opened them up and found that my left driver wasn't seated properly and was kind of just dangling. After putting it back in place it's been perfect. Good luck

It may cost you half of headphone price to fix, why not to upgrade, it is the time.

The muter diaphragm likely does not have enough excursion depth, usually this is because of an unwinded coil or wrinkles on the diaphragm. There's less space for the diaphragm to move or its movement is constrained, hence it's muter. Either way, it's a sign the diaphragm had been overdriven in the past, or of a manufacturing defect.

Googan... Believe it or not... I just did that...

And it worked! Just as your 555s' left driver wasn't seated inside the clip properly, nor was mine! I popped it in with a little bit of force, and bam, my headphones have become perfect!

You're amazing. Here's to you, and the random problems that we share!

Congratulations, it wasn't as serious.

Sorry for the bump, but I only registered here to say that I had this exact same problem with my HD555's, except that, as it turned out, it was the right side driver/coil/whatever that wasn't properly seated.

So thanks folks for this thread for giving me the idea to actually open the thing up and pop it back in.
