These new players from Samsung will replace a couple of older models, where the S5 takes over the K5 while the T10 is said to follow up on the K3. As for the S5, it comes with integrated speakers, a 1.8″ color display, and the ability for you to hook up a wireless headset via Bluetooth, giving you more freedom without feeling bogged down by pesky wires. It can even play video, although I wouldn’t put too much faith in such a tiny display. As for the T10, the only details currently available are video playback, Bluetooth connectivity, and a pretty impressive battery life of 30 hours. No idea on pricing, availability, and capacity of either though.
