This was one of the best earpiece experiences I have ever had. I used it at gym and work. It was awesome! Incredibly good sound, especially for its size. The battery life is amazing. Charger is easy to use, and when it comes off the charger, it is on, connected and ready to go. I also use this earbud when ever I drive. I can have a conversation with others in one ear and still be able to hear anything that goes on the road. Definitely will be buying more for gifts!
Output:
positive
