β Frequently Asked Questions
Q: How does 500-hour standby work?
A: The AI power management system keeps the device in ultra-low-power standby between sound events. It wakes to record when sound exceeds 30dB, then returns to sleep. This dramatically extends battery life compared to continuous recording.
Q: How much can it store?
A: The built-in 8GB stores approximately 280 hours of sound-activated recordings. Add a 128GB Micro SD card for 1,500+ hours. Browse compatible memory cards here.
Q: Is there a version with earphones included?
A: Yes β we also sell an identical model with earphones included for on-device playback. This version is designed for PC/Mac playback or OTG mobile access. Earphones are only needed if you want to review audio directly on the device.
Q: How is this different from the 500hr model with earphones?
A: This version does not include earphones. The features and specifications are identical. Choose this if you'll primarily play back on a PC or Mac; choose the earphone version if you want on-device listening.
Q: How is this different from the Mini LCD recorder?
A: The 500hr recorder has a much longer battery (500hr standby vs 16hr), higher audio quality (384Kbps vs 192Kbps), and supports expandable SD storage. The Mini LCD has a screen for visual status. Choose this for long-term unattended deployment; choose the LCD model for regular shorter sessions with visual feedback.
