Yes, you can connect it to external speakers or headphones via any of the four AUX ports, and the independent drivers ensure no signal interference even when using multiple outputs.
Does the timer automatically shut off the device after the set time?
Yes, it does! The timer automatically shuts off the device after the set time, which is perfect for my nightly sleep routine without worrying about leaving it on all night.
Who are the target users and what are the usage scenarios for this generator?
It is very suitable for people with light sleep, easy anxiety, high work pressure, and meditation lovers. It can be used in bedrooms, study rooms and offices to relieve fatigue, calm mood and improve sleep quality.
