I don't know much about the earphones you're talking about, in face I've never heard of the brand before, but I'm a big fan of in-ear headphones and the wiring problem usually happens when you pull on the wiring of the headphones. When I do run into similar problems with earphones and headphones I just open them, and re-solder the wires back to the respected connecting pieces.
But you really shouldn't have that problem with earphones retailing over $30 unless someone is pulling on the wires.
My V-moda bass headphones ($40 from J&R World) have stopped working again. I bought my first pair June, 07, after about 6 months the left ear gave out so I sent them to VModa, they sent me a new pair. Well the new pair has given out after only 3 months. I have read on the reviews here on Cnet about this issue happening with Sony's, Sennheiser's, etc. Is this a problem with just in ear headphones or does cheap wiring lead to problems in over-ear and other headphone types? I am wondering if I should just scrap the in ear model and get semi-open like the newly reviewed Koss Porta Pro's or another style? I.E. will this happen with any headphone style and any price range?
