Query: Good value for the performance

I got this a week ago. So far I'm pretty satisfied with the performance. I hear very clear and loud and the other end did the same. The battery is holding a charge very well. It can be used for either left or righ ear which is a big plus. The only complain I can say is the part that goes behind the ear it is quite big, it extends below my earlobe making it unsightly. But I can not complain for its performance and price. i saw one just like this for more than $20 more.
