LG. get your act together. Every so often I can't stop myself from complaining. This is one of those every so oftens. No visibility. Insufficient tactile differentiation among the controls. No labeling of which side is right and which left which matters, both because these are stereo earphones and because the identical looking and feeling buttons do different things on the two sides of the device. Manuals that use incredibly tiny type small type in gray on a black background. Badly written as well, but we have come to take that as standard. Usually we can figure things out anyway by playing with the controls. Not these controls. They are invisible in use (deliberate), but with insufficient tactile distinction, with the left controls identical to the right one, but doing different things, and no way of knowing which is left and which right, so on each usage, they will vary randomly.
