BFKK L357 128GB voice recorder

The BFKK L357 is a 128GB digital voice recorder designed for students, teachers, businesspeople, writers and anyone who needs a portable dictaphone for lectures, meetings or interviews. It captures stereo sound at 1536kbps using a dynamic noise reduction microphone with PCM intelligent noise reduction and 360° pickup. Adjustable recording gain across seven levels helps capture distant or quiet audio. The metal body is built for durability.

Simple two-button operation and USB-C charging

Operation is reduced to two buttons: press REC to start and STOP to save. Recordings can be saved in WAV or MP3 format and files are named with a YYYY-MM-DD-HH-MM-SS timestamp for easy identification. The built-in 500mAh battery charges fully in two hours via Type-C, providing up to 20 hours of continuous recording or 35 hours of playback. Voice-activated recording with seven sensitivity levels pauses during silence to save space and time.

Suited for scheduled voice capture.

This recorder suits users who need voice-activated capture, scheduled time-slot recording, A-B repeat, variable speed playback and easy file navigation via an optimised menu. It is not designed for high-fidelity music recording, multi-track production or video synchronisation. Buyers who need wireless transfer, smartphone app control or expandable storage beyond the fixed 128GB should consider other devices.
