The OS-43 is one of the first MP4 players to use the newer RK2708 media chip made by Rockchip. Although the chip is similar to that of its predecessor, RK2706, the RK2708 adds a little extra punch allowing smoother video playback and handle Slide Navigation System (SNS).

The SNS differs from other button and touch screen systems. The SNS is built around a tactile strip on the side of the player with a heat sensor underneath to detect finger movement. Moving your finger across the strip will interact with the GUI allowing for easy scrolling. The SNS makes it much easier to scroll and browse through your music library, unlike most 4.3? MP4 players which makes browsing quite cumbersome.

Your audio and video isn’t just confined to your player either as the OS-43 has TV out capabilities enabling you to watch any video you have stored on any TV with RCA inputs. It also has a built in FM transmitter which can be used to transmit your audio from your videos or music to a nearby radio, perfect for use within a car on those long trips.

The player comes with 8GB and 16GB of internal memory and a microSD slot (SDHC support) allowing up to 32GB of additional memory to be added to the player.
