Dear backers,

First, we are sorry for keeping you waiting for a long time, but we have lots of news to share with you, Arc is very close to mass production.

Regarding ear data collection, we are in the final stage of validating our algorithm to ensure every backer could update ear data smoothly. This process will be achieved on our official website which is very critical and needs to be done very carefully. Due to the scale and complexity of this part, we are scheduled to complete this by March 10th.

Needless to say, it is a huge undertaking to produce a new kind of custom-fit earphone which nobody has ever done or invested so much in all sophisticated molds to make. Here we have designed a whole new silica structure for the best fit earphones. Arc has 36 sizes and each of them needs an independent mold. This demands huge capital and time investment for development, fine tuning and product optimization. To this date, we have successfully tested and validated five sets of molds to improve the process step by step, and are able to produce Arc conforming precisely to its final design and quality standard, by cooperating with the best mold manufacturers.


Thousands of visitors, including some of our backers, have tried Arc custom made for them during CES. Almost everyone highly appreciates its unprecedented comfort. We also made some small modification based on the feedback, mainly around earplug to improve noise insulation without any compromise on comfort experience. In other words, every backer will get an upgraded Arc and we promise you will love it. We do expect about one month of delay to deliver Arc to you, and we do hope to have your understanding, as this is not a simple but very needed change, and it needs to be implemented on all 36 Arc sizes. The enhanced Arc will be so much better.

Thank you again for your patience, understanding and support. We are just so close.

      Where is the final coin list? The Google doc file shows Australia as a 50 cent coin but the latest image shows 50 cent. Can this go on the website? Thanks

      I uploaded the pic on website but haven't received any responses. I used the same email address as I sing in here. Is it ok now?

      Should the backers upload the pictures? I haven't received any emails saying so, but it looks like some people did.

      Thanks for the update... no worries, better to get it right the first time then to send out a flawed product from the start. Guys are doing good, keep it up. You should know by now, you have the support of many

      Good update. I'm comfortable waiting an extra month for you to get the details right.

      Thank you giving us an update. I'm sure I can speak for most backers when I say that I am perfectly content with a one month delay if it means an even better product. I certainly understand the delay, and appreciate the information you have given. I can't wait to get my new earphones!
