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.
Summary: I Love it! It does everything it said it promised. I would highly recommend this product. I bought extra just in case it is not available if I need another one down the road later. It is very comfortable. No discomfort. You can hear and be heard very clearly. These earpieces are not always available. I think LG should consider bringing more on the market. I am a highly satisfied customer.
