Coming from the world of photography I know two camera lenses from a manufacturer can perform differently even though they are the same model.
I’ve purchased two pairs of APP2 usb-c about two weeks apart. The second pair has better ANC and the first pair. They both have the same firmware now, but came with different ones installed. The first pair was definitely older as it has the original firmware and the second pair was one firmware behind the latest which means they were made more recently. The first one was made in Vietnam and the Second in China. I just find it so odd to be able to hear such a difference in ANC. The only other variable is the eartips but both were new and size medium. Has anyone else bought more than one pair and compared them?
