In addition to the electrical connection (yellow 3.5 jack), you need to connect the blue 3.5 jack to the SOUND output of the amplifier in your audio system - in my case! or to the SOUND output of your television set, if I'm not mistaken!
Halllo Hobri, as A. Nonymous says below - the base station should receive power as well as the audio input from the TV. The battery in the headset will charge when it is properly placed on the base station. - You don't need to worry about the wireless connection from the base to the headset, it always works. - When charged, remove the headset from the base and spread the earpieces to insert the plugs into the left and right ear. The spreading process switches the headset on. - Now you only need to press the "+" on the front of the headset (battery area in front of the chest) to turn the headset up (the TV can be muted, but the audio input of the base station must be connected). - If you still don't hear anything THEN... either the hardware or software could be faulty. But I don't think so. It's all very solid. Even if the headset falls to the floor (wearer falls asleep or something), it doesn't matter. Just don't step on it with your whole body weight, right? I wish you lots of fun troubleshooting and listening to TV!
