I had bought this Ubon Champ earphones at about Rs. 200/- few months ago. The model looked classy, and first 1-2 weeks, functioning and sound was Good, as expected. But the, defects started to appear, like often, one of the 2 plugs Malfunctioned. Either it was a defect of the plug, or internal defect.
Even on slight strain, wires would come out of the volume-control part. The speaker was good initially, but as the quality and functioning of the earphone Degraded, I lost hope in it, and disposed it.
Hence, I would mark this as a well-priced, but Defective model.
