OUR Vision

To lead a global shift toward quieter outdoor spaces, proving that progress does not have to be loud to be powerful.

OUR Vision

To deliver professional-grade performance without the noise, disruption, or compromise. Every Tone product is engineered to fit beautifully into your life, your neighborhood, & your routine.

From Question to Solution

For decades, leaf blowers have been one of the most hated everyday tools. Gas models have roared through neighborhoods. Electric blowers have traded that roar for a piercing whine. Communities have passed bans and restrictions. While millions of people demanded something better, no one solved the real problem: how can air be moved powerfully AND quietly?

In 2022, our team of aerospace engineers decided to find out if technology designed to propel aircraft could answer this problem. What started as a bold experiment eventually became the T1, the most powerful and quietest handheld leaf blower on the market.

Proof of Concept

The team prototyped its first leaf blower using a Whisper Aero propulsor previously flown on its UltraQuiet™ demonstrator drone. Results were so spectacular that a small, skunkworks effort was greenlit.

2023September

ANSI Validation

Field testing of a second leaf blower prototype was conducted to quantify acoustic benefits over existing commercial-off-the-shelf alternatives using industry standards. Testing occurred in rural fields at dawn because of the prototype’s low noise profile.

2024March

SXSW Live Demos

Community acceptance testing was held during SXSW at LaunchTN’s Tennessee House activation with positive feedback. Product considerations were gathered to combine with internal tech breakthroughs.

2024September

EQUIP Expo Demos

The team demonstrated Whisper Aero’s UltraQuiet technology benefits at the largest international trade show for outdoor power equipment and proved that its tech breakthroughs were truly industry-leading.

2025March

Design Iteration

Engineering and Industrial design teams iterated through various handheld leaf blower concepts and compositions. User interfaces and experiences were validated through rapid prototyping.

2025September

Engineering Validation & Testing

The first T1 Engineering Validation & Testing (EVT) builds were assembled at Tone’s manufacturing line. This effort proved the design could be mass manufactured and highlighted areas to improve before locking the design.

2025October

Color, Material, & Finish Lock

Industrial Design and Product teams tested numerous colors, materials, and finishes before settling on Canyon Sage. The popularized idiom “Silence Is Golden” led to a second premium colorway.

2025November

Tone Brand Reveal

At Elevate Expo 2025, the team revealed Tone for the first time and released the first T1 teaser.
