Systems and methods are provided for operating a pair of earbuds based whether the earbuds are being worn by the same user or different users. In this regard, one or more processors may determine, based on sensor signals from the pair of earbuds, whether the pair of earbuds are being worn by a same user or different users. Based on determining that the pair of earbuds are being worn by the same user, the pair of earbuds may be operated in a first mode so that one or more functions are controlled based on a first set of input settings. Based on determining that the pair of earbuds are being worn by different users, the pair of earbuds may be operated in a second mode so that the one or more functions of the pair of earbuds are controlled based on a second set of input settings.

A method including: transmitting, by a control device, a first portion of content comprising a first portion of a signal corresponding to a multimedia presentation characteristic of a peripheral device; receiving, when an adjustment of the signal is below an adjustment threshold, a first instance of an input indicating a request to change the multimedia presentation characteristic; in response to receiving the first instance of the input, adjusting a second portion of the signal and transmitting a second portion of the content comprising the adjusted second portion of the signal; receiving, when the adjustment of the signal is at or above the adjustment threshold, a second instance of the input; and transmitting, in response to receiving the second instance of the input, a communication signal to the peripheral device to adjust a peripheral device control of an output of the multimedia presentation characteristic.

A wireless power system includes a wireless power transmitting device such as a wireless charging mat for charging devices such as a cellular telephone and an earbuds battery case. The earbuds battery case receives earbuds and charges the earbuds from a battery. The wireless charging mat supports bidirectional in-band communications between the cellular telephone and the earbuds battery case. The earbuds battery case provides the cellular telephone with information on the battery charge level associated with the battery in the earbuds battery case and a battery charge level associated with each earbud in the earbuds battery case. The cellular telephone receives battery charge level information through the wireless charging mat and displays corresponding indicators. The earbuds battery case has a visual output device such as a light-emitting diode that is illuminated to indicate that the earbuds battery case is being charged.

Embodiments of this application disclose a call method and an apparatus. In the call method, when a user does not actively select an audio device as a voice pickup device and a voice play device, after establishing a call connection to another electronic device, an electronic device selects, from available audio devices, an audio device that meets a user expectation as the voice pickup device and the voice play device. According to technical solutions provided in the embodiments of this application, user experience in a call process can be improved.

This specification describes an apparatus for controlling audio output. The apparatus provides first and a second audio components for output to first and second audio transducers of a wearable device, determine a proximity between the wearable device and a third audio transducer and determining a first or second state of the first and second audio transducers, and controlling output of at least one of the first and second audio components based on the determined proximity and the state of the first and second transducers. Responsive the proximity being under a threshold and the state of the first transducer being in a first state whilst the second transducer is in a second state, the apparatus causes output of the audio component associated with the second state transducer to be transferred to the third audio transducer whilst continuing to output the audio component associated with the first state transducer to said transducer.

A hearing protection device is presented. The hearing protection device includes a first hearing protection unit and a second hearing protection unit. Each of the first and second hearing protection units include a microphone that receives ambient sound, a processor that provides level dependent attenuation of the ambient sound, and a speaker that broadcasts the sound into a user's ear. The hearing protection device also includes a first communication unit, which broadcasts a digital push-to-talk signal over a first communication protocol. The first communication protocol is a low energy communication protocol. The hearing protection device also includes a second communication unit, which broadcasts a digital communication signal over a second communication protocol. The hearing protection device also includes a processor that facilitates pairing of the hearing protection device with a mobile device that receives the push-to-talk signal and, based on the push-to-talk signal, receives the digital communication signal and transmits the digital communication signal over a cellular network.

An example system according to an example of the present disclosure includes a wireless headset having a speaker and a microphone. Control circuitry is disposed in a vehicle and is in communication with a plurality of vehicle systems. The control circuitry is configured to provide alerts through the speaker based on information from the plurality of vehicle systems indicating occurrence of trigger events, and to determine when to provide each alert based on a priority level of the alert within a multi-level hierarchy of priority levels.

The present application provides various embodiments for a Bluetooth headset or other wearable communication device that pairs via a Bluetooth protocol with a two way radio (hardware or software), thereby enabling hands-free activation and deactivation of the paired two way radio. Intelligent speech control is enabled for the two way radio using a start phrase to trigger talk or transmit mode of the two way radio and an end phrase to trigger the receive or listen mode of the two way radio. Tones can be emitted when a mode is entered as feedback to the user as to which mode the two way radio has entered.

A method for identifying a second device by a first device for establishing a communication between the first device and the second device is described here. The method includes receiving, by a processor of a first device, a voice command from a worker in a workplace. In an example, the method comprises pausing, by the processor, a workflow operation executing on the first device. The method further comprises performing, by the processor, a voice recognition to analyze the voice command of the worker. The method includes activating, by the processor, a communication module of the first device based on the voice recognition, to identify a second device in proximity to the first device. The method includes terminating, by the processor, a connection between the first device and the wearable electronic device. Thus, terminating, by the processor, a second connection of the first device with the second device.

Provided are a Bluetooth data transmission method and apparatus, a terminal and a storage medium. The Bluetooth data transmission method includes: detecting the number of connected Bluetooth devices and types of connected Bluetooth devices; determining, according to the number of connected Bluetooth devices and types of the connected Bluetooth devices, attribute states of the connected Bluetooth devices; and transmitting, according to the attribute states, to-be-outputted Bluetooth data to one of the connected Bluetooth devices.
