Abstract: A communication apparatus (1), such as a mobile phone, a tablet computer or a laptop computer, provides charging reminders to the user of a connected peripheral device (14), such as a headset. The charging reminders are provided in dependence on an auxiliary status signal (AS) received from the peripheral device (14) and on detected charging events (ME), wherein a main charging event (ME) comprises a charging or replacement of a main battery (2) that energizes the communication apparatus (1). The auxiliary status signal (AS) indicates an auxiliary energy level (AL) of an auxiliary battery (15) of the peripheral device (14). The communication apparatus (1) detects low-battery conditions (LC), based on the indicated auxiliary energy level (AL), and provides notification signals (NS) for a user interface (11) to notify the user of the detected low-battery conditions (LC) in response to the detected main charging events (ME).

Abstract: An earphone (1) comprising housing (2), a speaker (3), a speaker protrusion (4) extending along a protrusion axis (Z) and comprising an inner protrusion surface (12) and an outer protrusion surface (6), a resilient eargel (5) comprising an inner eargel surface (10) and an outer eargel surface (13). The eargel (5) is detachably attached to the speaker protrusion (4), such that the outer protrusion surface (6) abuts an abutment part (17) of the inner eargel surface (10) in an abutment zone (27) extending along the protrusion axis (Z). The eargel (5) is adapted to be inserted into the outer ear of a user, such that it abuts the ear canal of a user, whereby a cavity (7) is provided between at least the speaker (3), the inner protrusion surface (12), the inner eargel surface (10) and the ear canal. The earphone (1) is provided with a vent channel (9) coupling the cavity (7) and the ambient, wherein the vent channel (9) comprises a groove (8) in the outer protrusion surface (6) or the inner eargel surface (10).

Abstract: Disclosed is a headset for audio transmission. The headset is configured to be worn by a user. The headset comprises a speaker for sound transmission into the user's ear. The headset comprises a wireless communication unit for communication with an external device. The headset comprises a connection to a location-based service software, the location-based service software is configured for controlling at least one headset feature based on location data of the headset. The headset comprises a processing unit. The processing unit is configured for obtaining current location data of the headset. The processing unit is configured for enabling the location-based service software to detect if the current location data of the headset corresponds to a geographic region for which a first geo-fence is defined by the user.

Abstract: A headset adapted to transmitting an outgoing audio signal (Tx) and comprising a voice microphone and at least one ambient microphone. The headset comprises an ambient noise reduction block (ANR), which is adapted to reduce the level of ambient noise in the outgoing audio signal (Tx). The ambient noise reduction block (ANR) includes the measuring the levels of the voice microphone signal (X) and ambient microphone signal (Y) to estimate a characteristic constant level drop between the voice microphone signal (X) and the ambient microphone signal (Y), which is characteristic for the headset user talking. A time-varying filter passes the voice microphone signal (X), when the level difference is larger than characteristic constant level drop (CLD) and attenuates the voice microphone signal (X), if the level difference is below characteristic constant level drop.

Abstract: A headphone (1) comprising a first earphone (2) and a headband (3) to be arranged around the head of a user. The headband (3) comprises a first headband part (4) and a second headband part (5), that are telescopically connected, so that the length of the headband (3) can be adjusted in a longitudinal direction (Y). The first headband part (4) comprises an inner wall (9) with a protruding longitudinal first rib (8), which first rib (8) has a first rib sidewall (35) with a first rib protrusion (33) and a second opposite rib sidewall (36) with a second rib protrusion (34). The second headband part (5) comprises an outer wall (7) with a first longitudinal groove (6), which first groove (6) has first groove sidewall (20) with a first groove protrusion (22) and a second opposite groove sidewall (21) with a second groove protrusion (23).

Abstract: A headphone (1) comprising a first earphone (2) and a headband (3) to be arranged around the head of a user The headband (3) comprises a first headband part (4) and a second headband part (5), which are slidably connected to each other, so that the length of the headband (3) can be adjusted in a longitudinal direction (Y). There is provided a controlled friction mechanism, that controls the friction between the first headband part (4) and the second headband part (5). The friction mechanism comprises a first cantilever (8) comprised by the second headband part (5) and a first friction element (11) of elastomeric abutment material, which is attached to the first cantilever (8) and which due to elastic deformation of the first cantilever (8) abuts and exerts a force against a first contact area of the first headband part (4).

Abstract: The earphone (1) is adapted to be arranged in an operating position at a first ear (5) of a user (4) and, in the operating position, provide a first acoustic output signal (SO) to the first ear (5). The earphone has a first input unit (31) adapted to receive a first audio input signal (SI); a first noise cancellation signal path (37) with a first microphone (26) and a first noise cancellation filter (32), wherein the first microphone (26) is arranged to receive ambient sound (SA) from ambient space (7) with the earphone in the operating position and is adapted to provide a corresponding first reference signal (SR), and wherein the first noise cancellation filter (32) is adapted to apply a first transfer function (H) to the first reference signal (SR) to provide a first noise cancellation signal (SC).

Abstract: An audio communication system is disclosed. The audio communication system comprises a speaker device having at least one speaker, a first wireless communication unit and a first connector part; a dongle having control functionality, a second wireless communication unit, and a second connector part, the dangle being configured to operate in a first mode being an audio communication system pairing mode and in a second mode being an audio communication system operating mode.
