Affordable replacement microphones

Microphones degrade over time. Water, dust, and dirt affect the microphone and make it less sensitive. Therefore, we have developed a more affordable microphone, so you can replace an old microphone when it no longer meets your needs.

USB-C charging and file transfer

No hassle with exchanging batteries. Just charge the internal battery with a USB-C charger and your BATLOGGER S2 is ready to record. And downloading the recordings is as simple as pluging in a USB drive.
