Real-time coaching

Hearing means improving.

Swimming is the kind of sport where students do not hear the coach because their ears are underwater.
We have created a real-time communication device for training.

Technology

Evolved to perfection.

Every gram of Sonr is either state of the art technology or a patent-pending solution.

Improved bone
conduction

Low power consumption

Unique ultrasensitive
antenna

Unsinkable

It took nature a million years to develop vocalization for whales.
It took us two years to make an incredible thing - reduce the size of the receiving antenna from 12 to 2 cm with reliable reception at a depth of 1 meter.

Hear underwater.

Bone conduction delivers clear sound directly to the inner ear.

You hear the same great sound no matter where Sonr is placed on the head.

Hydrodynamics.

Headphones stick out, ears protrude, being touched by hands when swimming.

Sonr is 0.6 inch thick and weighs only 0.5 oz, therefore creates zero water resistance.

Designed to win

Swimmer friendly.

Swimming equipment leads to discomfort squeezing the head for grip.

Our unique disk-shaped Sonr fits ergonomically under swimmer's cap making you forget it's even there.

Don't like wearing a cap? Sonr is designed to be fixed on your goggles strap.
Don't like wearing goggles? You can always use Sonr headband.

Bone conduction

Single-point bone conducting design delivers crystal clear sound directly to the inner ear.

You hear the same great sound no matter where Sonr is placed on your head.
