Dedicated Record Button makes recording fast and simple because you need only to press it to start and stop the recording.
The device has a display with three full subpixels per pixel, resulting in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
The device has a filter to reduce background noise.
Voice recording feature allows you to record voice memos, notes, lectures, etc.
The device has a standard memory slot (such as an SD or micro SD card slot) so that you can either extend the internal storage with affordable memory modules or you can retrieve data, such as photographs, easily from a memory card.
The battery can be recharged and used over again.
You can record your lectures, music, notes, ect. directly to a SD card, which gives you more flexibility regarding storage.
With a standard mini jack socket, you can use the device with most headphones.
