    Abstract: A car speakerphone (10; 32; 47; 48; 49) to be attached to a sun visor (4) in the cabin of a car (5), which sun visor (4) is of the type, that can be rotated about a first axis (38) into different adjustment positions (P). The speakerphone (10; 32; 47; 48; 49) comprises a speaker housing (11), at least a first microphone device (2, 9, 45, 53, 55) with a directivity (41) and including at least a first microphone (2, 14-21). The speakerphone comprises adjustment means (22, 23, 24, 25; 27; 31) for adjusting the directivity (41) of said microphone device (2, 9, 45, 53, 55) in relation to the sun visor (4). The adjustment means (22, 23, 24, 25; 27; 31) are adapted to automatically adjust the directivity (41) of the microphone device (2, 9, 45, 53, 55) as a function of the adjustment position (P) of the sun visor (4).

    Abstract: A headset system comprises a headset (51) and a base station, wherein both headset (51) and base station comprise a transceiver configured to transmit radio signals between headset and base station according to a first wireless communication protocol. Both headset (51) and base station further comprise a transceiver configured to transmit radio signals between headset and base station according to a second wireless communication protocol; and at least one of said headset (51) and said base station further comprises selecting means (29) configured to select one of the first and second wireless communication protocols for transmission of radio signals between headset and base station. When both headset and base station have transceivers for two different wireless communication protocols and one of these can be selected for transmission it means that the combined number of channels can be used, which increases the number of channels that can be used simultaneously.
