I wasn't trying to "break" my SE846. In fact, I have treated it delicately since day one. Nevertheless, the right side earpiece stopped working today. As others have testified, my experience (as well) with Shure's customer service has always been excellent (for nearly a decade). This is the first non-cable related issue I've ever had with theirs (or any) earphone. It's hard to imagine what the issue could be.....
Whether "burn-in" is real, (or a matter of grey-matter), I swear this past week is the best the 846 has sounded since I got it in early September (or was it late August?). Anyway, the right earpiece just stopped like a light bulb After listening to podcasts on my iPod, I plugged in the Note 3 to listen to some music (and after a few songs) the sound was only coming out of the left side.....
I feel invested in this "burned-in" unit so I'm going to give it another day (of futile voodoo dances or something) and then back to Shure it goes. I've connected it to four different Shure cables (and various players) and I've changed the filters (why? I don't know). I would surround it with garlic and burn a toothpick cross if I thought that would help.
Oh well, it's back to the 535/ T'Mo Galaxy S2 (with Android 4.4) for now. It has sounded pretty good lately. It's as if the new rom has freed up resources for Poweramp. And while the 535 is no 846, it's a good backup. My turnaround experiences with Shure has been one week. What I'm dreading is getting back an earphone (or one earpiece) that needs 1000 hours to sound like the one I loss today.
I'm going to tell myself over and over again that "burn in" is nonsense. Mind over matter, right?
