Smart home equipment provides a solid hardware foundation for the full-scenario trend of night listening, and the sector is expected to experience tremendous growth in the future, Zhu said.

Recognizing those promising prospects, many smart equipment manufacturers are already taking action.

In September, United States tech heavyweight Apple Inc launched the Apple Watch Series 5. The light portable watch can be connected with earphones via bluetooth.

It has a new feature called noise alert, reminding users to lower the volume when the decibel level rises to the point it may affect the hearing of people. The new feature is especially practical for night listeners, who tend to put on loud energetic music during the night.

On April 23, Chinese telecom giant Huawei launched an artificial intelligent speaker featuring music, audio books, weather forecasts, news and traffic condition suggestions.

"With advanced technology, the evenings for night listeners have become more colorful," Zhu said.

As promising as the future seemingly is, industry experts noted that some bottlenecks for the sector still exist.

For instance, the material for night listening needs to be enriched and refined so consumers are more willing to pay for content. Cash flow is also an important motivation for authors to create high quality content. Enterprises should think of ways to break that dilemma, the experts said.
