Sound-Activated Voice Recorder USB Flash 16GB-128GB — 500Hrs Continuous Recording, Long Standby, Noise Reduction, One-Touch Operation

Quick start: Charge the recorder fully before first use. If you add an SD card, format the card before inserting it. Key features: 1) Long battery life — 500Hours continuously recording time; 180days standby time; 400hours playing time with earphone. The unit also supports recording while charging. 2) Intelligent, sound-activated recording — the device only records when sound is detected and stops during silence. Files are timestamped so each recording is named by time. 3) Simple one-touch operation — start recording with a single press and save with one click; powering off automatically saves files. 4) High-quality audio — DSP smart noise reduce for clearer sound and 1536KBPS recording bit mode for lossless, hi-fi audio. 5) Privacy protection — you can set a power-on password so that, without it, recordings cannot be used or copied. When power is low or the unit is disconnected, the recorder saves the current file before shutting down to prevent data loss.
