❓ Frequently Asked Questions
Q: Why choose this over the standard 500hr model?
A: This version includes earphones so you can listen back to recordings directly on the device — no PC or phone needed. Ideal if you're reviewing recordings in the field or away from a computer.
Q: How much can it store?
A: 8GB stores approximately 96 hours of continuous recording. Add a Micro SD card (up to 128GB) for 1,500+ hours. Browse compatible memory cards here.
Q: How does 500-hour standby work?
A: AI power management keeps the device in ultra-low-power sleep between sound events. It wakes to record when sound exceeds 30dB, then returns to sleep — dramatically extending battery life vs continuous recording.
