128GB Magnetic Voice Recorder

The HEVAVW L810 provides 128GB of storage for lectures, meetings and interviews. A magnetic body allows attachment to metal surfaces for discreet placement. It connects to computers or smartphones via USB 3.0 Type-C for file transfer and management. The package includes a microphone and a 3.5mm headphone adapter for playback.

40-Hour Continuous Recording

The device runs for up to 40 hours in continuous recording mode. Voice activation starts capture only when sound exceeds 45dB, conserving storage and battery during silent periods. A 60-degree wide-angle pickup captures audio across large rooms. The internal battery delivers 5 hours of operation per charge.

CSV Recording Format

Recordings are saved in CSV format on the internal 128GB drive. Settings such as date, time, bit rate and file segmentation must be adjusted by editing the MRECSET configuration file on a computer. The USB drive is only recognised when the recorder is powered off before connection.

Questions about this item

Does the 128 GB L810 generate noticeable heat or fan noise during a 40-hour continuous session?

The solid-state recorder has no moving parts and draws only 2 Wh from its lithium-ion cell, so it runs silently and stays cool even after 40 hours of recording.

What cable or adapter do I already need to move files from the USB 3.0 Type-C port to my phone?

You must supply an OTG adapter or a USB-C-to-C cable; the box includes only the recorder, a microphone and a standard USB cable.

Can I plug my older 3.5 mm headphones straight into the L810 for playback?

Yes, the recorder provides a 3.5 mm headphone jack that supports volume control, track switching and playback speed adjustment.
