So I recently purchased a HyperX Cloud Headset which comes with a audio/mic Splitter extension cable. Is there any difference in sound quality/performance running this to my PC oboard sound vs just using the standard 3.5 cable?
They're all the same. The core is the basic model with less/no real accessories, the Cloud I includes high quality leatherette and velour ear cushions, carrying bag etc and the Cloud II's include all of that + the 7.1 surround sound card.
