Is it safe to keep the wires assembled?

Question

Iron

Please tell me, is it safe to use headphones with wires in the assembled state, as in the photo?

Answer 1

This will affect the sound so weakly that even with instruments it will be difficult to detect.
But it is better not to fold loaded power cables. If you roll the extension cord into rings and connect something powerful, such as an electric heater, you will notice how these rings will heat up. Sometimes until cheap insulation melts → short circuit → fire.

Answer 2

And my headphones are already 9-10 years old. And they have part of the wire just stupidly hardened. Doesn't bend at all.
And it has something to do with hands. Where he took more - there harder.
