A sound direction/stereo effect 3D adjustable earphone in one aspect contains an adjustable headband clip to hold the left and right earphone parts. An adjustable holder is at the left and right ends of the earphone and at the topside of an ear cup. The ear cup contains a 3D adjustable ear speaker at the center of the earphone for delivery of sounds from the earphone to a user. A 3D direction adjustable unit works with the ear speaker. The adjustable unit contains a connector such as a little ball at one end to fit in a corresponding connector such as a hole at the holder and another connector such as a little ball to fit into another corresponding connector such as a hole at the speaker. In this way, the ear speaker can be freely pushed out/pulled in and pulled/pushed/rotated adjustably in X-Y-Z or three dimensions.
