The cables for the right and left ear are of different lengths, so that the main cable is routed to the left on the body.
The headphones work. But more can not be expected also. The sound I find dull. It is as if you can hear the music through a handkerchief.
Also, there are the first headphones, where I hear signal interference (hum) is idle.
For 3,99 I did not expect much. At the sound, however, I had not quite expected so little.
