Couldn't find them in Hong Kong but didn't really look much. I bought them here Jaybird Freedom Bluetooth Headphones JF3MB (Midnight Black) Prices & Features - Expansys Hong Kong (ç£çŸ³Â· ç’°çƒæ•¸ç¢¼åŸŽ) very fast delivery.
The mic is ok , while walking or running i usually take the right ear-bud in front of my mouth to speak and mic is perfect. Harder to do while cycling.
