Hi guys! i've acquired a pair of jbl headphones (J88i) and i'm noticing a problem, the left side (the side with the audio cable) sounds louder than the right. It seems like the right side has less amplitude on low frequencies than the left one but the mids and highs sound kinda the same on both. The fact that there is less bass on one side makes them sound unbalanced. (i'm testing them with a mono signal, just to make sure its not a mixing problem)


Is this common?? it seriously annoys me, please if you guys have any advice i would be really grateful. Maybe there is a common fix, or maybe it is known problem. Should I contact the provider for the guarantee service?

Thanks in advance, Nicolas.
