NinTaBro 72GB Voice Recorder for lectures

The NinTaBro voice recorder ships with a 72GB microSD card included and records in WAV format. It is aimed at students, professionals and journalists who need a portable capture device for lectures, meetings or interviews. Voice-activated recording starts automatically when sound is detected and pauses during silence.

Check USB and headphone connections

The device connects to a computer through a USB 2.0 Micro-A port for file transfer and the one-time VOR setup. Playback uses a 3.5 mm headphone jack. Verify that your computer has a compatible USB port or adapter and that your headphones use a 3.5 mm plug before ordering.

A 270 mAh rechargeable battery provides up to 20 hours of continuous recording or 25 hours of headphone playback after a 1.5 hour charge. The recorder weighs 0.141 kilograms and uses a DSP 4.0 chip with 360-degree dynamic noise-cancelling microphone, which runs cool and silent during normal operation.
