The sound of the PX7 is very broad, clean, balanced and detailed. I have not set the phone to 120hz refresh rate. My son uses this to listen to his audio books and some movies on the ipad. In the process it adds distortions making sound less clear. The price was right for these however. across the shoe top and arch. Bin mit dem Hosenbügel sehr zufrieden. (ahem) iphone, so if I?m going to use this kind of charger, it?s going to need to last. Gday all. My foot is very narrow and so are my ankle so I added extra holes for the buckle.
