What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

  • two comfortable earbuds for stereo music enjoyment
  • earbuds snap magnetically into place in the charging case and stay there safely
  • innovative 2-in-1-charging™: simply connect your charger to C-one™ while C-one™ stays attached to your device to charge both, C-one™ and your phone at the same time – travel light without yet another charger and cable
  • C-one™ supports 2-way-charging™, meaning your device will slowly charge C-one™ and make sure you’ve enough charge on your headset for that important call
  • attach C-one™ to your mobile device via a reversible Micro-USB connector and never wonder where you (mis-)placed your headset anymore – you have it with you wherever you bring your phone
  •  

C-one™is giving you back 

time, the most valuable good in our hectic lifes, for example and
ease of mind with the convenience and ease of use to make your life a little easier.

  • Enjoy listening to your favourite tunes instead of spending time to untangle the wires of your headset.
  • Travel a little lighter as you don't need to bring yet another charger or cable for your headset - that's good for you and the environment (we take it one step at a time).
  • Relax and know you have your headset with you instead of getting distracted and heated searching for your earbuds just to find out you've left them safe and sound sitting on you desk while you're out and about.
  • Be confident and place your earbuds back into the case right at your phone easily and avoid the embarrassed moments of taking out your earbuds when meeting someone you'd like to talk with in person and shake hands while not knowing where to quickly put the earbuds ... not to mention the time needed to re-discover where you then actually did place them.
  • Easily pick up a phone call by taking the C-one™ earbud out from the charging case. There's no need to press the power-on button or wait for the pairing procedure. You only do Bluetooth® pairing once with you device and C-one™ will remember it when waking up from the charging mode and re-establish the connection with your device automatically and quickly. It's like picking up the telephone receiver on a traditional desk phone.
  • Declutter your desk - one less cable as you charge C-one™ together with your phone

The story of C-one™ 

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™.

C-one prototype
C-one prototype

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.

stylish and comfortable
stylish and comfortable

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-jumping with great pleasure.  

Comfortable to wear
Comfortable to wear

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.  

Why choose C-one™? 

What sets C-one™ apart 

is our charging and carrying case design with the patent pending 2-in-1-charging™ and 2-way-charging™ functions.
The C-one™ charging and carrying case can be attached with the reversible Micro-USB connector to the charging port of your mobile phone or other mobile device.
With this you’ll have C-one™ with you when and where you need it and wherever you bring your mobile device. And it’s not another device to carry around – C-one™ and your device become one.

For 2-in-1-charging™, simply leave C-one™ attached to your device and plug in your charger cable into the C-one™ charging port. Now both, your device and C-one™ will be charged at the same time – no additional cable or charger required.

2-way-charging™ will refresh C-one™’s power reserve by slowly re-charging the build-in battery in the charging and carrying case with a low power provided by your device. This requires your mobile device to be USB OTG enabled and, depending on the implementation on your device, may need our 2-way-charging™ adapter plugged into the C-one™ charging port.

Alternative ways to use C-one™ 

Alternative to the obvious way to attach C-one™ to your mobile phone and use it for your daily communication needs and motivation power tracks playback, you may plug C-one™ into your tablet or computer and extend your wireless communication to Skype, Skype for Business, Wire or similar applications and at the same time having a safe and easy solution where to place your headset when not in use.

C-one™ doesn’t require additional space on your desk and keeps you organized and in control.

 C-one™ Specification 

C-one™ user interface 

For ease of use and increased durability we simplified the interfacing on the C-one™ earbuds to a single button and a single LED indicator. No accidental triggering of unwanted calls or functions by swiping close to the earbuds shall spoil your fun with C-one™.

How to use C-one™?

For ease of use and increased durability we simplified the interfacing on the C-one™ earbuds to a single button and a single LED indicator. No accidental triggering of unwanted calls or functions by swiping close to the earbuds shall spoil your fun with C-one™.

Primary Earbud refers to the earbud you used for the Bluetooth® pairing with your device.
You have your individual preference which ear you use for your primary earbud and that is good. Just like with skateboarding or snowboarding, some people go left foot in front (normal stance) and some prefer goofy-style.
We don’t want you to adapt to your headset, no, we want you to feel comfortable and let the headset adapt to you.
You choose if your primary earbud is for your right ear or your left ear. Everything else follows naturally.

Use C-one™ with iDevice

For our friends and supporters using iDevices, our Flex Edition of C-one™ includes an adaptor to connect the C-one™ Micro-USB connector to your lightning charging port.
The 2-in-1-charging™ feature is tested and working, so you can charge C-one™ and your iPhone at the same time with only one charger.
Please note, the charging input on C-one™ requires a Micro-USB connector. A fitting cable is provided with C-one™.

Due to most iDevices not providing OTG functionality, the 2-way-charging™ feature does not work with iDevices and C-one™ may not get charged from your iDevice.

Of course, you can always carry and use C-one™ also stand-alone without attaching it to your device. The provided Micro-USB cover will help to protect from scratches and also keeps C-one™ safe.

Use C-one™ with USB Type-C powered device

For our friends and supporters with Devices using USB Type-C connectors for charging, our Flex Edition of C-one™ includes an adaptor to connect the C-one™ Micro-USB connector to your USB Type-C charging port.

The 2-in-1-charging™ feature is tested and working, so you can charge C-one™ and your Phone at the same time.
With the use of our charging adaptor, C-one™ can also get charged from your device as the 2-way-charging™ feature is tested and functional. Please note, the charging input on C-one™ requires a Micro-USB connector. A fitting cable is provided with C-one™.

Of course, you can always carry and use C-one™ also stand-alone without attaching it to your device. The provided Micro-USB cover will help to protect from scratches and also keeps C-one™ safe.

Timeline

About us 

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. 

JTLK Limited is incorporated in Hong Kong.
With my experience, C-one™ and the Kickstarter platform, I aim to enable JTLK own product designs in the wearable market.

Risks and challenges

Timing is always a challenge with the production of a new product.
However, we have been working with top-notch suppliers and are in continuous communication with our suppliers to drive towards the targeted schedule.
Being based in Hong Kong, we regularly visit our production supplier to monitor the quality.
We’ll personally check every shipment that will go out to make sure all backers receive the product in the best quality.
The challenge will be the fulfilment side rather than the production. We now have some margin in our delivery times, and hope to deliver all C-one in a timely manner.
