Users can quickly complete operations without taking out their phones in sports, travel and other scenarios, improving the convenience and efficiency of use.
Voice Assistant Integration: Deep integration of headphones with voice assistants on mobile phones or other devices (such as Siri, Xiaoai, Xiaodu, etc.). Users only need to wake up the voice assistant through specific voice commands or touch operations to achieve voice interaction.

For example, users can ask the voice assistant “What’s the weather like today”, “Play Jay Chou’s song”, “Set an alarm for tomorrow morning at 7am”, “Navigate to a nearby coffee shop”, etc.

The voice assistant will execute the corresponding operations according to the instructions without manual input, especially in scenarios such as driving and busy hands, providing users with a safer and more convenient way of operation.

4、 Call function
The true wireless in ear Bluetooth earphones are equipped with a high-sensitivity microphone, providing users with a clear communication experience. During a call, the microphone of the headphones not only needs to pick up the user’s voice, but also effectively suppress environmental noise to ensure that the other party can hear their speech clearly. For this reason, many headphones adopt noise cancelling microphone technology, which works together with multiple microphones to achieve accurate recognition and reverse cancellation of environmental noise.

Common noise reduction techniques include dual microphone noise reduction, triple microphone noise reduction, etc. Dual microphone noise reduction generally involves one microphone picking up the user’s voice and the other microphone capturing environmental noise, generating reverse sound waves through algorithms to eliminate the noise; On the basis of three microphones for noise reduction, an additional microphone is added to further enhance the noise reduction effect, ensuring clear communication even in noisy environments such as streets and subways.

In addition, some headphones also support intelligent adjustment of call noise reduction algorithms, which automatically adjust the noise reduction intensity according to the size of environmental noise to achieve the best call effect.

5、 Intelligent featured functions
Wear detection: The earphones are equipped with built-in infrared sensors or acceleration sensors, which can detect in real time whether the earphones are worn on the ears.

When the user removes the headphones, the sensor detects that the headphones are detached from the ear and automatically pauses audio playback to avoid wasting power when not in use; When the user puts the headphones back into their ears again, the headphones will automatically resume playback without manual operation, bringing users a more intelligent and convenient user experience.
Intelligent noise reduction: The active noise reduction function is a major highlight of true wireless in ear Bluetooth earphones.

The headphones collect environmental noise through a built-in noise cancelling microphone, and then use noise cancelling chips and algorithms to analyze the frequency and intensity of the noise, generating opposite sound waves to cancel out the environmental noise.

The noise reduction intensity can be divided into multiple levels, and users can freely adjust the noise reduction intensity according to different usage scenarios, such as in the office, on the plane, in the library, etc., through a mobile app or headphones touch operation, creating a quiet listening environment.

In addition to active noise reduction, some headphones also have ambient sound mode, also known as transparency mode.

In this mode, the headphones will introduce external environmental sounds through the microphone, allowing users to not only listen to music, but also clearly perceive the sounds of the surrounding environment, such as the sound of vehicles driving, conversations with others, etc. In scenarios such as crossing the road and communicating with others, users can enjoy music while ensuring safety.
Search for headphones: When users accidentally lose or forget their headphones in a certain place, they can use the headphone search function on the mobile app to find them.

If the headphones are turned on and connected, the APP can make the headphones emit specific sounds to help users quickly locate the position of the headphones; Even if the earphones are turned off, some earphones support Bluetooth positioning technology to display the location information of the earphones when they were last connected on the APP, providing clues for users to find the earphones.
6、 Battery life and charging function
The battery life of true wireless in ear Bluetooth earphones directly affects the user’s experience.

The earphones themselves are equipped with lithium batteries.

After a single full charge, they can play music continuously for 4-8 hours depending on the brand and model, meeting the needs of users in daily commuting, work, study and other scenarios.
