No technical knowledge needed but little patience.
Do this first, just press the cable to catch in the female mmcx connector and you shd hear an audible tick sound which means thay are correctly in contact(grip/intact)). Now check the sound.
And if you could'nt succeed,Its a removable cable, so try pulling out the cable gently with one hand and hold firmy the shell on the other.....its not that hard,be little relaxed.I know what ur going thru now. But you gotta try it self to confirm its really a defective one.
Also the nozzle is part of half shell than vsonic's swivable/rotating one so it shd be ok to try on your side.
These mmcx are better than 2 pins(UE,Westones) so spin ur wheel.
Thanks Shawn, i'll try that once I get off work.
Even though I'v been on the receiving end here, I don't want to take anything away from Vsonic. I used the Vsonic GR02 Bass Edition for 2 years before it gave out, that too probably coz I started sleeping with it and damaged the cable somehow while turning, I'm a pretty hefty guy. Build quality wise Vsonic actually feel better than many other companies. Build quality is an issue with me too, and that's also one reason I have Stuck with them.
