Grundig Digta 422
Dedicated Record Button makes recording fast and simple because you need only to press it to start and stop the recording.
The device has an LCD display with 3 subpixels per pixel, resulting in sharp and crisp images. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
A microphone port allows connecting external high-end or specialized microphones.
Voice recording feature allows you to record voice memos, notes, lectures, etc.
More microphones result in better sound quality and enable the device to filter out background noise.
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.
You can record lectures, music, notes, etc., directly onto an SD card, which provides more storage flexibility.
With more USB ports, you are able to connect more devices.
