Experience with various gadgets and devices combined with keen observation and careful listening to what people really want was the starting point of the journey leading to C-one™.

The desire to make communication easier, more comfortable, more convenient and enjoy music while being active without adding yet another device and charger and cable to the list of items to carry during commute, travel and leisure resulted in the design of C-one™.

A well integrated design makes having C-one™ with you feel naturally, is easy to use for communication and provides music to the connoisseur as well as powerful options for the business user.

Stereo vs. single ear, balancing battery power vs. size and weight or the orientation of the earbuds for the most natural way to pick up and carry are just some of the challenges resolved on the way.

We focus the design to be aesthetic, minimalistic yet providing the desired and required functionality.

The weight distribution of the earbuds ensures long time wear won’t cause any discomfort nor will the earbuds fall out during running, jumping and exercise – yes, we actually tested this and used C-one™ while rope-skipping with great pleasure.

Comfortable fit for most persons is ensured with the shape of the earbuds and the fitting can be further adapted individually with the provided eartips in different sizes.
You may even try with different sizes on each ear to find your perfect individual fit.
After all, you want to enjoy your favourite tunes while exercising for fun and good health and not be distracted by a slipping headsets.

Various design ideas challenged by the reality of required space for implementation.
Just to list some of the topics we had reviewed, challenged ourselves and finally came up with solutions for:

• the battery size and dimension,
• the position, direction and finally the angle of the earbuds residing in the charging case,
• innovation of the overall charging concept, resulting in our unique 2-in-1-charging™ and 2-way-charging™, and of course
• different views on design aesthetics.

Always with the aim to provide for you the desired functionality and usability in an aesthetic and appealing design, we worked relentlessly, innovated, tried different ideas and approaches and tested various options to ultimately reach the final design of C-one™.

I’m Thomas Markfelder, a German Electrical Engineer (Dipl.-Ing. Univ.), living in Hong Kong for the last 16+ years.
My experience grew from starting as a project manager for a German semiconductor company to help build a local support centre for Asian mobile phone makers using our mobile phone development platforms.
The role expanded to Director of Program Management over the years with some broadening excursions into Global Platform Product Marketing, Ecosystem management and also Business Development.
With the acquisition of our division by a big US semiconductor company the focus area expanded from mobile phones towards enabling communications for PCs, Tablet Computers and also IoT (Internet of Things) devices.

Today, I build on the experience gained from working with various customers, Tier 1 mobile phone makers, design houses and PC makers, in Korea, SE-Asia, China, USA and Japan and also apply my intercultural EQ that I was fortunate to hone with my cross-cultural and cross-functional team of project managers and experts in various disciplines.

With my experience and C-one™, I aim to enable JTLK own product designs in the wearable market.
