1. A hearing instrument comprises:
- an in-the-canal hearing device in an ear canal of a user and having an acoustic pick up and means for amplifying a signal from said acoustic pick up and emitting sound waves in said canal;
an electromagnetic-wave wireless behind-the-ear device located behind the ear of the user and provided with a signal pick up element, an amplifier and an electroacoustic transducer; and
coupling means between the behind-said-ear device and the in-the-canal device and including an elongated signal delivery element having an open end tube, said open end tube connected to an output of the electroacoustic transducer of the behind-the-ear device and running into the canal at least proximal to the in-the-ear device for delivering amplified signals from the behind-the-ear device to said in-the-ear device.
