So what exactly do these shiny new earbuds have to offer? According to Mashable's Bethany Allard in her piece on everything to know about them, published following the latest Galaxy Unpacked event, "The Buds4 Pro come with an audio improvement in the form of a wider woofer. Up from a 10.5mm DD woofer on the Buds3 Pro, the newer gen will feature an 11mm SuperWide woofer. It is worth noting, however, that the Buds3 Pro featured a 6.1mm planar tweeter, while the Buds4 Pro feature a 5.5mm planar tweeter."
