I've used it in classrooms and meetings, and its voice-activated mode reliably picks up clear, natural speech without picking up background noise-perfect for focusing on essential details.
With just two buttons, EVISTR is effortless to operate: press "rec" to start and "Save" to end recordings.

Voice activation is the standout feature. I've set it to high sensitivity for lectures, and it reliably picks up the teacher's voice while filtering out background noise. The playback controls-A-B repeat, rewind, and variable speed-are smooth and responsive. However, the 32Kbps compression can slightly reduce audio clarity compared to higher bitrates, which might be a downside for audiophiles. The file management is straightforward, but transferring files via Type-C requires a computer, which isn't ideal for quick edits on the fly. it's a solid choice for students, professionals, and casual users looking for a durable, user-friendly recorder.
EVISTR L357 excels in scenarios where simplicity meets performance. Its professional-grade noise reduction and 1536kbps stereo sound make it ideal for capturing detailed conversations,though it may struggle with very distant or low-volume audio. The voice-activated feature is a lifesaver for lectures and interviews, ensuring no critical moments are missed. While the lack of advanced editing tools is a minor drawback, the seamless file naming and quick transfer options make it easy to organize. The 18-month after-sales support gives peace of mind, and the compact design is a plus for portability. Still, the reliance on a computer for file transfers might be inconvenient for some users.
