Ok we have not done any test, Its just a feeling. This little device has been a good helper in the everyday work. Instead of holding your cell to the ear for hours you can just put the Jabra in your ear and let the cell lie in your pocket.

You dont even have to take it up to recive a call, just press your ear to awnser. And hey, its very small to, just 10g.

We recomend the Jabra JX10 v2
