I don't think the ear pads or wings that were replaced were original but they were close enough that it didn't matter. The very first day I tried them, I made sure I had everything fully charged and took it to the gym and to the office. It easily took 10 hours but it could have been more. Quality is excellent on Samsung phones (using Samsung codec). The quality is good due to the regular SBC codec when used with a laptop. And saved a lot of money when buying a new one.
