Hello Franziska, these headphones can only be used via Bluetooth. But there is another version with a cable and a normal headphone jack. Hope this helps you. LA

Headphones charge with supplied USB cable

Unfortunately, no. I have also tried this and it does not work. Pairing can be done, but the signal only goes to one headphone (the one that connects first to the source). With two headphones, you therefore have to work with two Bluetooth sources. Otherwise, the headphones are great, my children love listening to their stories with them.

Hi, I had bought this headset for my daughter, there is no cable - only bluetooth

No it doesn't, If your concern is battery life, its fairly long and quite quick to charge. We have had ours for two years, and we haven't needed a wire connection yet.

Unfortunately, the headphones cannot be connected to a source device via cable, as according to the manufacturer there is no jack input/output.

I do not have this problem. Charging sometimes up to 24h...
