I ordered the XM3’s by mistake (because Sony’s nomenclature is ridiculous), and Sparts did a flawless swap for the XM4’s no questions asked and lightening quick. It’s refreshing to engage with a company who trust their customers and are kind.
It’ll take a little getting used to the new ear pads after five years of wear on the others, but the install was quick and uncomplicated with a slender screwdriver to pop the clips. You only realise how far your originals have degraded until you replace them with plump new ones. They feel sturdy and broad.
Thank you, Sparts!
