This video will show Vesper's High AOP Homepod speaker.

Here’s how Vesper’s microphone works.

Vesper’s piezoelectric MEMS microphone is fully operational when immersed in water. In fact, it can even work like a hydrophone so it can capture sounds that are otherwise impossible to record.

Vesper’s VM1010 piezoelectric MEMS microphone with ZeroPower Listening, DSP Group’s DBMD6 DSP, and Sensory’s keyword-detection algorithm – increases battery life from 8 hours in always-listening mode.

Vesper’s always-listening piezoelectric MEMS microphones let battery-powered devices stay in wake-on-sound mode without draining the battery.

At Vesper, we built a handler to test thousands of microphones at once. Our microphones arrive in trays, which are fed into our fully-automatic handler. Each microphone is individually tested in a sealed acoustic chamber.

Vesper’s quiescent sensing microphone is a pencil-point sized piezoelectric MEMS device that can activate idle electronics while drawing almost zero power in standby mode – using just voice input

Vesper's VM1000 piezoelectric microphone is incredibly tough and water-resistant, so we put it through the ultimate test - recording whales in the Boston Harbor.

BioMimetic Systems is a company which builds gunshot detection systems. They use microphone arrays to locate enemy fire and protect soldiers.

Vesper’s always-listening piezoelectric MEMS microphones let battery-powered devices stay in wake-on-sound mode without draining the battery. They are also waterproof, dustproof and particle-resistant – so they make smart devices truly mobile.
