After about 5 months and nearly half a dozen emails asking them what's going on, I got a replacement to my faulty VSD1S via BigBargainOnline (ebay). Considering I still had to pay to ship them to China, this was in no way worth the effort/time. I ended up having to buy replacement headphones in the meantime since it was unclear if I'd ever hear back from them.
Anyway, I've been using the replacements they sent (with the updated snake cable) for about 4 months before one of the ears went out. This is the third Vsonic earphone to fail at the plug. I've never had this problem with other headphones. Why would they go to the length of updating the cable without updating the pathetic strain relief?
I've loved how all the VSonics have sounded, but I'm sick of buying a new pair every few weeks/months. The alternatives I bought (Shure SE215) aren't breaking anytime soon, but they're way too bulky to carry around in my pocket...which usually means I just take my portable cans. Sennheiser CX300's fit the bill perfectly, I just thought they sounded subpar.
p.s. I've failed both times I tried to solder a replacement tip. The cables are just too tiny, and the probability of getting a short too high. I'm sure it's possible with defter hands, but really, save your sanity.
