The few grams, the cable is kept in a plain black and both plug are gold plated and the company name Sentivus printed. But you can of 4 different colors (blue, black, red and white) choose. The 20 cm long cable is rolled so easily off it can be up to a length of nearly 50 cm. But you can also cable with a greater length order Here you can choose between 20 cm, 35 cm and 50 cm. The cable is sturdy and know of a good quality, because you never can find any faults, the contacts are well made. The length is also ideal for devices to connect to each other or to connect the phone to the car radio and fool it into the tray. Since it is rolled there is no risk of verfitzens but it's just a voltage on the cable over long distances and light things prefers thereby automatically to the infected machine. The build quality is great, too, it seems durable and everything is meticulously crafted, so you are not afraid of cable breakage, loose contacts, etc.. Benefits can be equipped with all appliances which have a 3.5mm jack connection, of course. I tried it with different Smartphone`s as Iphone or Samsung with a portable speaker, as well as on the home system. Both jack is associated with a reassuring click, because you realize that it is equally properly connected. It will operate properly when play music, no noise, crunch or the like. The music is clearly transferred to the device. For me it remains infected and also comes off not easy, even if a bit of tension on the cable is rather my phone is pulled to the device ran, what I see is not quite as positive about it. Especially in the car, it is a bit difficult then the right depends my smartphone in the air. To solve the problem I have often drawn long time, thus it rolls not so good at but it's a bit longer thereby become. Otherwise this audio cable is great, just at the price of just under 6 euros you can recommend it without any problems.
