Not quite sure what to make of this ... yet I'm at my witts end here. Seeking if anyone has suggestions.
Basically I got these (brand new) a matter of days ago, and they sound absolutely beautiful (best sound that I've ever heard from a pair of ANC headphones), with one exception. I hear a "crackling" or "shifting" sound in the right earpiece intermittently. It's somewhat almost like sound that you'd expect from the padding being deformed, rubbing against hair, etc. Except I know that it's not as I hear the sound even whenever not moving my head. (sounds like a "zzzzzzzzzzzzzzt")
Now the weirdness begins.
--If I use the noise canceling function on the headphones and have them connected to nothing ... no-problem. No crackle in the right ear.
--If I connect the headphones to my SoundBlaster ZXR, crackle in the right ear even playing "no audio". Other headphones of mine such as my Sennheiser PC350's and Sony MDR's DO NOT pick up any weird sounds like I'm hearing. My desktop speaker system is also not picking up this crackle.
Ok ... so it's the machine in some way causing it, I'd thought. Nope, it gets weirder.
Connecting the headphones to just an extension cord, free-hanging, not plugged into "anything" results in crackling in the right earpiece. Remove the extension, crackling goes away. Connect the headphones straight into machine, no extension, crackling occurs again.
Any suggestions? I've already tried fixing an Iron Ferrite Core right on the cable before the connection to the headphones.
Are my headphones defective, or is something like RF getting picked up in the extension somehow and in my computer's hardware? **Note that it's always ONLY the right speaker, and never the left**
Trying to figure out if there's anything else I should try, or if I should RMA the headset.
Any advise is appreciated, even if it's just a confirmation that you think they're defective.
To add a bit more here. I've not been able to reproduce / trigger the crackling by playing any frequency or volume. I don't notice any increase or decrease in the distortion / sound regardless what I'm playing. It seems entirely intermittent.
I've also tried using a different cable to the headphones, and removing their detachable cord. It doesn't seem that it's the headphone's cable or connector ... unless it's the jack on the headphones itself.
