Update on my situation, Rockit Sounds has offered to refund my purchase amount. Good customer service and responsibility for the manufacturing defect. I am happy they have handled the situation responsibly.
Now I am on the lookout for something to replace the R-50, as its build quality is leaving me worried. Also, I auditioned my brother's TDK BA200 today, and found myself liking some of its characteristics, like it's weightier, more full-bodied representation of bass and percussion instruments. I did find the R-50 often a little unnaturally thin on percussive instruments like drums. However, I find the BA200 a bit too smoothed-over and laid-back at the top, I miss the sparkle and bell-like clarity of the R-50's treble.
Is there something you guys can recommend, that is sort of like an R-50 with a slightly fuller bottom-end, but without sacrificing as much treble extension and presence as the BA200? I can spend up to USD 180 or so.
I'm not saying to buy these, but to research GR07 MK2, they sound similar to R-50, but fuller bodied, thicker.
