There is provided a transmission system for a wireless mobile electronic device, comprising: a ground plane (20); a first antenna element which is separate from the ground plane and which is implemented as a strip (30) comprising a feeding end (31) configured to be coupled to a transceiver (60) for feeding an RF signal to the first antenna element and a free end (32), wherein the strip comprises a first arm (33) including the feeding end and a second arm (34) extending at an angle from the first arm; and a second antenna element (40) separate from the first antenna element, which is shorted to the ground plane so as to act as a parasitic element. The first and second antenna elements are located adjacent to each other at an end (23) of the ground plane, the second arm of the first antenna element points towards the second antenna element, and the arrangement formed by the first and second antenna elements has no symmetry plane.

A hearing device (10) to be worn at least partially in the ear of an end user, the hearing device comprising a primary microphone (12), an ear canal microphone (13), a comb-signal detector (14), and an all-pass filter (15) that is connected to the comb-signal detector (14) and a receiver (19). The all-pass filter (15) is configured to receive a first input signal (20) and to modify an output signal (16) for the receiver (19). The ear canal microphone (13) is configured to generate a second input signal (21) for the comb-signal detector (14). The comb-signal detector (14) is configured to receive the first input signal (20), to detect the presence of notches (24) in the second input signal (21) that are indicative of the comb filter effect (25), and to issue control parameters (22) to the all-pass filter (15).

In-ear device (10) that is at least partially insertable into an ear canal of a user. The in-ear device comprises a housing (13) that is mechanically releasably coupled to a connector (12) by way of a dedicated opening (15) provided in the housing (13). The connector (12) is made of an elastic material, a tubular overall shape defining a longitudinal axis (11) and radially delimits a sound channel (18). The connector (12) is mechanically releasably coupled to a loudspeaker unit (27) at a second end (17) of the connector (12). A cerumen protection unit (25) is connected to the connector (12) by an adhesive-free and non-losable connection.

A hearing device component (6) comprises a sensor-unit (8) for receiving an audio-signal (AS), a separation device (9) for separating part-signals (PS<i>) from the audio-signal (AS), a classification device (10) for classifying the part-signals (PS<i>) separated from the audio-signals (AS), and a modulation device (11) for modulating the part-signals (PS<i>), wherein the classification device (10) is communicatively coupled to the modulation device (11) and wherein the modulation device (11) is designed to enable a concurrent modulation of different part-signals (PS<i>) with different modulation-functions depending on their classification.
