It could be re-cabled if you're handy with that kind of stuff, otherwise it's time to get a new set. Ksearphone / Temperament have released a newer version, the X series which features a partially replaceable cable.
X10 = lowest end, X6 = LBS / LBBS, X3 cost more, but not sure if they = LBS / LBBS but with different colored shells and comes with both 3.5mmSE / 4.4mmBal cables as standard. X6 can be had with just 3.5mmSE (approx. $38) or with both 3.5mmSE and 4.4mmBal cables (approx. $53).
I just got my x10 today, I was able to lower my volume to 20%.
It sounds the same except the bass seems boomier compared to my lbbs. Wonder if I should have gotten the pricier version, but I don't really want to if it will just break in 2 years again.
These chinese buds never last. Every single one I've used for more than a month have broken.
