The Premium Audio spiral cable (jack) of the company Sentivus I was asked by testberichte.reviews for a review is available. The cable was delivered in a straightforward and small packaging which can be easily opened. The cable makes the same at first glance a good impression. The male acting stable and the cable is good, secured with a small kink in the plugs. The silver polished connectors and gilded handles look very high. I have the cable repeatedly stretched to about 1.8m and leave for several hours so. Clear that the spiral cable loses some form at this time and no longer goes back quite to its original shape. Nevertheless, it draws repeatedly to acceptable size together and remain so compact. I tested the cable with several mobile phone, MP3 player and stereo. The connectors are in all the devices fixed right and do not wobble. The contacts are good - it's not hear any noise or the like. The signal transmission seems to be ok. Perhaps it is possible to consider someone with corresponding electronic education the signal transmission of the cable with a gauge yes here. I can in any case recommend the Premium Audio spiral cable (jack) of the company Sentivus. An audio spiral cable with gold-plated handles, good design and good signal transmission for under 6.- is a very good price / performance ratio.
