Problem with Corebook i5 speakers

Problem with Corebook i5 speakers.
The sound of the speakers is strange, it seems like an echo and when you move the balance it does not change between right and left, the right chanel is stronger. The sound is practically mono.
It seems as if they are connected in serial mode.

Could you please tell your exact model and the serial number. It was happening before, just after you bought or is something that appear after time?

Thanks, it´s a ZCore BDW2H230400644. Since I bought it, it sounds like this.

It sounds like there may be an issue with the speaker wiring or the audio settings on your Corebook i5. I would recommend checking the audio settings in your device’s control panel to ensure they are configured correctly for stereo sound. If the issue persists, you may need to contact customer support for further assistance or consider having the speakers inspected by a technician.
