My sister in the United States bought this for me (I'm in the Philippines). I told her that i needed an earbuds that could hang onto my ears, and not fall, and wireless, and chargeable. When she came, she gave me just what i wanted. The design is what I wanted. It looks neat and cool. I could ask for nothing more. In addition, the time for full blast listening is long, and it is turned off automatic after i place them inside their case. I like using it as I am always going outside. And in the gym its perfect where i could hear only my songs. I don't have any thoughts for exchanging it for some new design. This is what i needed and wanted. Thank you for creating this innovative device.
