An electroacoustic device includes a rear body portion containing electronic circuits, being so dimensioned and shaped as to be carried by a human user behind the user's ear and having an upper end portion and a frontal body portion with an upper end portion connected to the upper end portion of the rear body portion. The device may include an electroacoustic speaker transducer connected to the frontal body portion and arrangeable in a sound transmitting relationship to the user's ear canal when the device is carried by the human user. The speaker transducer may be rotatable about an axis which is arranged on a plane that is substantially parallel to the side of the head of the user when the device is carried by the human user.
