Looks my TV has not possibility to connect to 3,5mm jack:
Hello, I am sorry, your TV does not have a headphone jack. You should say that it is a debugging interface. The debugging interface is a dedicated interface for debugging the TV in the factory before leaving the factory. User use will not have any effect. It is not recommended to plug any cable into this jack. You can download a Hisense TV micro assistant, open it and select the tool~Transfer to the secret, you can use your phone to plug in the headphones to listen to the sound of the TV.

You can take a full picture of the back of the TV and show it to me.

我有一臺電視更大的海信LED58K300U與相同的Android系統(tǒng)，并有同樣的問題。當連接耳機插孔到電視聲音時，電視聲音應該停止播放只有聲音應該在耳機，但注意發(fā)生！如果在2臺電視機海信LED58K300U和海信LED49K300U上有同樣的問題，那么它似乎是Android系統(tǒng)的問題。請幫忙！

Direct insertion of headphone output noise is very large, may be that the wire is not well connected ...
