Questions?

We’ve got answers

How loud is the alarm?

Hearo emits a 135dB alarm, which is as loud as a jet engine at takeoff. It’s designed to immediately draw attention and can be heard from a significant distance.

Is Hearo legal to carry & can I take it on a plane?

Yes! Unlike pepper spray or tasers, Hearo is legal everywhere. It’s airline-approved, meaning you can carry it in your handbag, backpack, or personal bag while traveling.

Is the alarm rechargeable & how long does the battery last?

Yes! Hearo is USB-C rechargeable, so you never have to replace batteries. A full charge can last up to 18 months, depending on usage.

Low Battery Warning: If the battery drops below 10%, Hearo will emit three short beeps every few hours and after you reinsert the pin, so you’ll always know when to recharge.
