We have a different structural design- a clean, minimalist design - with a nice finish aluminum casing- as most creators are using plastic for their case designs. We're using chip-set CSR63120, and the latest Bluetooth V4.2.
Simply use your fingers to pull the bud off from the case. You can see the video we shot that shows how the bud snaps on to the case (see the prototype resource section we've included in a link at the bottom on our KS page.) We will also shoot a new video of this soon to show backers more closely in an update.
The buds can play for 2-hours continous play per charge. Using the case they can charge three times for a total of 6 hours of use. If using middle or lower volume, they can last a maximum of 8 hours of use.
You can always change your pledge to higher reward. Just click the blue "Manage" button that appears next to the current pledge amount then select "Change your pledge". From there, you will be able to adjust your pledge amount and your pledge will update automatically.
