Pros: battery life is good, answering button is easy to press without pushing it into the ear.
Cons: died after less than 4 months of use, just stopped charging when being plugged and when it is plugged it just heats up and becomes prone to possibly melting or catching fire if one does not notice this problem. 4 months use for the price is horrible.
Pros: Great audio, long battery live, loud , good range.
Cons: The clip that goes over the ear broke on mine, because I switch from ear to ear during long calls (It took over a year before it broke.). I switch from ear to ear, because in-ear the speaker is not the most comfortable.
