One Step Ahead, Once Again

While other connected measurement tools on the market work only with the analog and disappearing audio jack connector, ONEOF engineers developed a brand new digital audio electronic system based on the commonly used USB standard.

No jack connector

The jack connector with analog audio is outdated. The 16 bits / 48KHz digital audio used in ONEOF Accuracy2 gives better measurement performance than any other product available on the market.

Plug and Play

The ONEOF accuracy2 is a stand-alone device. It requires no battery or power supply. Plug it in and forget it, it is that simple.
