Every time I go out on the train, there are those orphans who are playing Douyin and Kuaishou at the maximum volume. I can't take a good rest. I plan to go out with a jammer later, big guys help me.

Answer
You can use a small handheld wifi jammer, and the power bank can be used to power it, but the power of such a device is very small, and it can only block a small range. After the blocker is turned on, the most affected should be your own mobile phone, so it is still Bring earplugs.
