The unique Open Directional Non-Invasive Sound (ODNIS technology™) allows you to listen to music or call with the neck speaker setup so you don't have to worry about disturbing the people around you. 

This is achieved mainly thanks to its uniquely engineered 4 speakers.

 The “Forbes magazine” of the audio industry, AudioXpress  (The Leading Global Audio Magazine) talks about our partnership with Mimi.

Shipping info will be collected at the end of the campaign. See FAQs for more details.


Mimi is the leading science-based hearing enhancement technology from Germany. Providing the best-personalized sound experience to a new depth for the Circulr's hybrid headphones by adapting the audio signal to your unique hearing and understanding of how you hear.

Mimi don't change the sound, it lets you fully experience it. 


How is Mimi different from an equalizer?

Mimi applies dynamic, non-linear processing to unmask the maximum audio detail to the hearer while maintaining the character of the sound. Linear, EQ-based approaches do not address masking, are more distortive to the original audio, and can push up the intensity in the already vulnerable frequencies for the listener. 

The result is the best natural fit for your ears.

The Neckphone TRi comes with on-ear pads by default

We’re passionate about music and enabling people to experience it fully.

In January of this year 2021, we were accepted into the Sound Hub Denmark Accelerator, which has a lower acceptance rate (3%) than Stanford (4.7%) or Harvard (5.2%). We focused to work on developing and prototyping with top sound experts in the world.


We’re now ready to move ahead with manufacturing and plan to start production in Q3 this year. This includes tooling, sourcing and regulatory certifications. Our product will be ready to ship by November 2022.

Our last Pitch at Sound Hub.

We know that most backers won't have the opportunity to experience the Circulr's Neckphone TRi before pledging, but we are confident that you are going to love your Circulrs'. We will reward your faith in us by offering a 30-day money back guarantee. It’s simple. If you don’t like the comfort or love the sound of your Circulr headphones, send them back within 30-days for a full refund.


Why Kickstarter


Music is meant to be enjoyed alone or shared anytime and anywhere with respect to others around us and safely. We’re beginning our journey to production with Kickstarter to share our passion with the community, and also to let the community share their vision with us. We believe that the backer community will play a vital role in the future development at Circulr.

Through Kickstarter, we aren’t just pre-selling our product with great discounts and raising funds to enable us to begin mass production, we’re also building relationships and learning from passionate, innovative, and visionary backers. We welcome your feedback on how we can make the experience of ultra-versatile sound on the go even better.
