icListen HF Hydrophone

We developed the world's first smart digital hydrophone, the icListen, setting a new global standard in underwater acoustic sensing.

The icListen delivers real-time listening, detects acoustic events as they happen, and records high-resolution data – all in one compact, rugged device.

Small enough to carry in one hand, our simple, accurate, and reliable icListens allow users to collect, analyze, and listen to ocean sound data in real-time.
