Aquarian Audio Products designs and builds quality hydrophones for the eco-tour or recording professional.  Though our hydrophones have been used in a variety of applications worldwide, including research, industry, medical and military, our focus is on creating products that offer an exceptional cost-performance ratio for those involved in auditory applications.  Our designs prioritize high sensitivity, low noise, compatibility with standard audio components, and durability.

One customer might use our H1 with a portable instrument amp to enhance his whale-watching kayak tour.  Another can use our H2 with a flash recorder and contact mic adapter to get the perfect field recording.  And yet another will use our H2-XLR with a professional video camera while working on the latest  documentary film.  Regardless of the application, we will do our very best to serve your underwater listening needs.
