@satyamy & Sourabh: Thanks guys! I'll look into both of them.
Is it a fact or myth that having a volume control knob on the wire, connecting the headphones to the system, can be a major source of headphone problems? (irrespective of usage) For I've experienced the volume control knob malfunctioning whereby it fails to select the proper sound channels as it boosts the signal, thus rendering the headphone pretty much useless.
