The cable was intended to connect an MP3 player via the headphone jack with active speakers. I did not expect anything special because of the price, but also a cheap cable has to work, which this not only did at least. The cable was measured by the ohm meter and had on all three phases passage, yet it was not working. The devices have been tested using a different cable, so that an error on the player or the pit could be excluded.
Conclusion: Except expenses nothing had happened. And Complaint Processing proved very laborious - of the complaint about an announced but never arrived replacement to the refund passed beaten 23 days.
