I'm not really sure how to title this and gain attention.. but let me explain my situation.
I've had a pair of Sennheiser HD598s for a little over a year now. My dog chewed the headband a little and while it does remain fully functional, it was terrible to look at. I couldn't readily find a replacement and didn't want to pay Senn. to repair them as there's no telling what it would cost. Well, I found a new headband a few weeks ago. A quick trip across the Atlantic and I had them in my hands Monday. Last night I went into the shop to do the job.
I'm sure you guys know how these are wired up. A double wire runs through the headband and the ends of the two wires are soldered onto a circuit board in each side. So, here is how I did the swap: Heat each piece of solder and pull the old wire out, careful not to distort the solder and move it. Then heat the solder back up and slide the wire back into it.
Left ear piece was a resounding success on removal and replacement. Right side.. I accidentally slipped and the pieces of solder ended up touching. So a quick heat up and I split the bubbles apart. At this point, this is the only thing that has gone remotely wrong, although it didn't worry me.
Ok, so a quick run back into the house and plug them back up and hey.. sound is working fine in both pieces and I have a new looking set of 598s.
So the problem is I sat down and started playing some music to listen to make sure there was no difference. I think I worried myself to the point I'm making myself hear things. In my head, I think I'm hearing certain notes (Not sure of correct term here) playing in one side but not the other. So question for you very technical guys.. Is there a possibility I could have altered the sound quality?
