I've owned the UM2RC for a month and they really are a step up from my previous set of earphones.
Recently, however, the right side seems to have less volume than the left. There is also a noticeable "cracking" sound when I increase the volume, especially prevalent on tracks with female vocals/treble.
I've tried to reduce the variables down by attaching the LHS cable with the RHS earbud and vice versa, yet the "cracking" sounds still seems to appear on the right earbud.
My question is that, can this conclusively be a driver problem on my right earbud? It is hard to believe as I have only owned it for under a month and followed the maintenance and care that is instructed on the manual (put in case, clean residue in canal, no moisture).
Of course, I do hope it could be a cable problem (although I have tested on many devices and songs and the right earbud is still the culprit) since it can be easily resolved.
The other possible reason I thought was perhaps I blown the driver? I play my music through a 5G iPod (no amp) on Rockbox at around -20dB...although I am not sure if that's sufficient to blow the driver.
TLDR: Right earbud "cracking" sound during female vocals/treble when playing music at higher volumes, cable or driver problem? It is possible for Westone to just repair the driver and reattach the housing/shell?
Any response is appreciated, just ever so slightly irritated how I purchased the UM2RC to anticipate cable problems and a potential driver failure occurs.
