The ability for an Android device to output alarm sounds via connected headphones is a feature addressing auditory needs. This directs the alarm sound exclusively to the user wearing headphones, instead of broadcasting it through the device’s external speaker. An example is someone using headphones while sleeping and the alarm sounding only through their headphones, preventing disturbance to others nearby.
The importance of this functionality lies in its capacity to provide a personalized and private alarm experience. Benefits include minimized disruption to roommates, family members, or fellow travelers in shared spaces. Historically, this feature developed in response to user demand for greater control over audio output and a desire to avoid unwanted noise pollution.
