Sound quality is ok, Bluetooth works well. Overall a decent device. What worries me is that you can't see the menu because the music stops as soon as you press the home button. I haven't found a tuner/eq, but the default setting isn't that bad. Worst of all is the resistive touchscreen. I bought a similar device for another $10, but the OS/GUI (Common User Interface) works much better. There are about a dozen different versions of the same device for the same price, it's just a matter of luck as to what you get.
