Unfortunately, you have no way to adjust the volume and unfortunately this is not I-Pod touch, and therefore probably not I-Phone-capable. If I am wrong, it may indeed write another user, thank me! Otherwise, the sound is great, but there are also cheaper, with the same sound performance. Having never had a devil-product and my last in-ear headphones have given up the ghost, I wanted to try it here. The cable is very thin in my opinion and I just find angeflachte better, because here I had often times do really to get them apart. But the workmanship is very good, but I'm not completely satisfied, otherwise I would have gladly given also 5 star.
