I know that the NE-6s are old news for Head-Fi, but I'm curious if anyone's had any issue with the build quality of these IEMs. My last pair developed a short in the plug after three weeks of careful use, and my replacement pair had a short in the plug on day one. It's definitely not my mp3 player's headphone jack - the headphones have the same short while hooked up to any source. I'm treating these no different than I've treated any of my previous headphones. I plug them into my Sansa Fuze and then stick the MP3 player in my pocket with the jack facing up. With my next pair, I'm going to use a headphone extension between the Fuze and the Nuforces to minimize any direct stress on their plug. But nothing like this was necessary with my previous pair of IEMs. Has anyone had any similar experience with Nuforce's lower end IEMs? I know this would void my warranty, but I was considering putting my own reinforced jack on the next pair when/if they have the same issue, rather than go through another return process. I'd prefer a nice stable pair of IEMs vs mailing these back for a replacement every couple months.
