Dear Backers and Friends,

I'd like to update you on the following three issues

• Preproduction
• Mass production
• A small batch (ready to go)

We finally finished the preproduction phase, and our next phase is the mass production.

Preproduction

The preproduction went really well. We identified a few areas that may go wrong in the assembly process, and the final assembly process is a manual of 40 steps.

Mass Production

As mentioned in the last update, the process leading to mass production is the following

• preproduction
• preproduction certified
• purchase raw materials for mass production
• negotiate a date with the manufacturer
• mass production

We know that it will take time for the raw material to come in from other suppliers, sometimes the lead time is 6 to 7 weeks long. As soon as we started the preproduction phase, we began to place orders for all the raw materials. As of now, all materials will come in about 4 weeks. We negotiated with the manufacturer for assembly line time slot, and the tentatively date is July 20, 2015. It's not guaranteed, and it may move ahead or back for a few days depending on a slew of other factors and the assembly line condition.

I'm asking for your patience with us. I understand that our initial estimate was for delivery in May, and we did our best to push for June delivery to you all. We are fortunate that we are in the home stretch now, there's no technical issues to deal with. We expect all the raw materials will be of the same quality as we had in the preproduction.

Initial delivery

We received a small batch of the BTunes yesterday (Monday, June 15, 2015) from preproduction which made 100 units. Over half of all units were tested to the extreme conditions, so they are not fit for distribution. They are kept at the manufacturer's location.

This small batch is good to go for some of you. I'm ready to ship. These are for models of 3.5mm (15 units), 2.5mm (24 units), and QC25 (3 units) and a few units for media which helped us to publicize the project during the BTunes' Kickstarter campaign.

I don't pretend that I know the fairest way to distribute these units. I think that a random drawing is a good way to start. What do you think of it?

I'm going to lock down on BackerKit.com by the end of day tomorrow (June 17). Hopefully we can start to ship before this weekend.

Best regards,

Dp
