Even several friends of mine and I have hearing loss

due to not wearing ear protection since we started."

Factors the dissonate young musicians from using hearing protection include price, awareness, and incentive (or lack thereof)


Reasons such as the number of drivers, customization, and the specificity of those products contribute to the rise in cost.

Signal Adapter

The object responsible for connecting every part together, it reads the input from the instrument and outputs it to the app, which is controlled, changed (or not), and then sent to the artists' ears.

Transporting Case

The system works in harmony, every part has its home, so carrying it from one place to another does not become an obstacle in any way.

How is it less expensive?

Number of Drivers

Expensive IEMs use 4 drivers, which exponentially increase the price, while having no scientific proof of their effectiveness, especially for beginning musicians.

Pulse uses a single one.

Estimated Price

Based on the estimated prices of OLED screens and touch-sensitive displays, in a 5-year future, a set's cost would range from US$200 to US$ 275.
