I just bought this cable for my QC25 headphones, having bought the version that came with the Apple cable by default.
The volume difference with this cable and my Samsung Galaxy S6 is absolutely different, and because of that I no longer have to max out my phone's volume settings to listen to music!
Looks almost the same as the Apple cable except that the control block has an "S" painted on it, which helps differentiate the two cables.
Volume controls work well, as does the pause/play button. Glad I purchased this!
