Ringtones are short audio clips that play when a phone receives a call or notification. They can be customized by users to reflect personal preferences, often featuring music, sounds, or even voice recordings. Ringtones can be downloaded from various sources or created using software. Many smartphones come with a selection of default ringtones, but users can also purchase or create their own. Popular genres for ringtones include pop music, classical music, and sound effects. Ringtones serve not only a functional purpose but also allow individuals to express their personality and style through their choice of sound.
