They look nearly similar to the F9 I bought in summer but compared to my old ones the are poor quality. The sound is tinny, they often do not connect into stereo. Left and right can only be detected on a small mark on the earphone. Impossible to see this in the dark. The older version comes up with a voice information for left and right.
I didn't receive my package
Please I called the China post and they say the package was sent back to you, it never arrived on my side
