I have the jack-jack cable ordered in 1.5 m in order to use it, among other things to connect the smartphone to the car radio. Processing acts outwardly very high quality and the front connector is so thin that it fits easily on my smartphone with protective cover. The first cable was unfortunately defective. From the left speaker came no sound, with another cable have both speakers work properly. Apparently lay before a broken cable. I have directly caused a return and turned me by e-mail to the customer by the dealer Memory King. My question was answered very quickly and I was immediately a free replacement cable sent. The new cable is working well so far and the sound transmission takes place without noise. I hope it stays that way. If the replacement cable later have a bad contact, I'll update the review.
