Tiny but Powerful
It's only 0.2 ounce, designed with an adorable mini appearance, but it provides an incredible 4-hour battery in using and 120-hour stand-by time by a full charge of less than 2 hours. When you wear it on, you will almost feel nothing, it never giving you any burden. Mini and tiny design, smaller than the size of your fingers, makes it nearly invisible. Tiny as it is, the sound coming from it is clear and crisp, great for music,audiobooks and podcasts.

Note
that answering a phone call through the buttton on the bluetooth earpiece will make the voice of the other much more clear than through that on your smartphone.
