In addition, a microphone can be present on the headset, which records the ambient sound. The ambient sound is converted into an electrical signal, amplified, converted back into an acoustic signal and fed to the ear of the headset wearer. As a result, the headset can be used as a hearing aid. The amplifier is adjusted so that a hearing loss of the headset wearer is at least largely compensated.

Invention will be explained below with reference to embodiments. It
1 a headset with a universal earpiece,
2 a headset with a universal ear piece and an adapter,
3 a headset with an individual earmold and
4 an individually shaped earmold with an annular holding part.
1 shows a schematic, highly simplified representation of a headset with a headset module 1 and a detachably connected with this ear piece 2A , The headset module 1 includes a transmitting and receiving unit 3 For wireless data transmission between the headset and a communication device with an antenna 4 connected is. For further processing and amplification of the received signals is a signal processing unit 5 available. The amplification is preferably carried out as a function of the frequency of the signals to be transmitted to compensate for a hearing loss of the headset wearer. The processed signals eventually become in a listener 9 transformed into acoustic signals and through a sound channel 7 , the ear piece 2A passes through, delivered into the ear canal of the headset wearer. The headset module 1 also includes a microphone 8th in that an acoustic signal emanating from the headset carrier is converted into an electrical signal and transmitted via the transmitting and receiving unit 3 and the antenna 4 wirelessly transmitted to a communication device.
The headset according to 1 can also be used as a hearing aid. This will be one of the microphone 8th Received and converted into an electrical signal signal further processed and in particular in response to the signal frequency amplified to compensate for a hearing loss of the headset wearer. The amplified signal is transmitted via the handset 6 delivered into the ear canal of the headset wearer. As the listener 6 and the microphone 8th are relatively close to each other, there is a high feedback tendency. This is advantageously prevented according to the invention in that the mouth of the sound channel 7A acoustically opposite the microphone opening 8A is sealed. According to the invention this is done by an ear piece 2A achieved, which closes the ear canal entrance as close as possible. Between the headset module and the ear piece 2A is a lock 9 provided a quick and easy connection between the headset module 1 and the ear piece 2A creates. Thus, it is possible that a plurality of ear pieces can be provided, wherein for the in individual headset wearer by trying on a suitable earpiece. Preferably, different ear pieces are offered for small, medium and large auditory canal diameter.
In addition to the sealing of the ear canal is the ear piece 2A Furthermore, the attachment of the headset on the ear. For this purpose, the earpiece is supported 2A in the concha of the ear. In order to improve the attachment of the headset to the ear, other fastening means may also be present, for example a holding part (not shown) which engages over the auricle.
Another example of a detachable with the headset module 1 connectable earpiece 2 B shows 2 , The ear piece 2 B is provided with circumferential lamellae, which rest against the auditory canal wall for sealing. Such shaped ear pieces are known in hearing protection devices and are referred to as "olive".
In contrast to the embodiment according to 1 is in the embodiment according to 2 between the ear piece 2 B and the hearing aid module 1 an adapter piece 10 , Preferably, both the connection between the adapter piece 10 and the headset module 1 as well as the connection between the adapter piece 10 and the ear piece 2 B solvable. Through the adapter piece 10 becomes the ear piece 2 B with worn headset further into the auditory canal into shifted. In addition, through the adapter piece 10 between the headset module 1 and the adapter piece 10 a standardized closure 9 used, for example, as it is known in the connection of the handset of a pocket hearing device with a trough. The closure 9A between the adapter piece 10 and the ear piece 2A is then adapted to the respective ear piece (eg of a particular manufacturer).
In contrast to the embodiments according to the 1 and 2 is in the embodiment according to 3 a specially adapted to the anatomical conditions of the headset wearer ear piece 2C used. This is made individually based on an ear impression or a measurement of the respective ear (laser scanning). The very precise, individual fit a very good seal is achieved at the same time high wearing comfort and good attachment of the headset to the ear.
4 shows that from the headset module 1 dissolved earmold 2C in the plan view, in which the annular holding part 11 is apparent. The earmold 2C preferably consists of a plastic, in which the metal, annular holding part 11 is poured or glued. The annular holding part 11 has two recesses 12A and 12B into which a correspondingly shaped nose of the in the annular holding part 11 gripping counterpart of the shutter 9 can grab. This will be during the rotation of the earmold 2C relative to the headset module 1 Latching positions generated in which the earmold 2C latched relative to the headset module. Un intended twisting of the modules relative to each other is thereby largely prevented.
In the embodiment according to 4 is the annular holding part 11 also partially of a groove machined in the plastic material 13 surrounded in the case of the connection of the earmold 2C with the headset module 1 one to the headset module 1 molded nose attacks. The two ends of the groove 13 thereby form stops that the rotational movement of the earmold 2C relative to the headset module 1 restrict to a certain angle range. This prevents the headset worn on the head from being turned to an unforeseen position, eg, a position in the microphone 8th (please refer 1 ) to the rear, ie opposite to the viewing direction, is aligned.
