Unfortunately, I can the review of "Speedmax" not! confirm. My cable from merchants' online queen ", which I have ordered only on the basis of this review, will not work on my iPhone 5s under IOS 7.1, when inserting the message" This accessory is not supported by this device ". It works just the charging function, the playing audio is on the original Apple impossible docking station. In this respect for me useless, the cable goes back. I can not judge why that is, the cable looks really absolutely original, nothing points to a possible forgery. I can still only say that it does not work with my iPhone. Maybe even a defect in the cable, one more try I do not in any case ...
