The connection via the headphone jack was smooth and the sound came immediately fill out the boxes and even after several hours of operation changed that assessment. The 3D option should be activated in any case, without this the sound is very one-dimensional and one wonders what you have now standing around but these relatively large box.
My TV does not have stereo output, I am still waiting for TOS to stereo converter, so I can not evaluate the quality of it, but worse than the headphone jack, it probably will not be.
Conclusion: very good sound result, absolutely fair price, and delivery on warehouse was surprisingly fast - only the manual was missing unfortunately included, but that is to get over.
