The C3948BI itself is impressive for the price. It handled the tremulous, high notes of Dmitri Shostakovich without sounding shrill, and it delivered the thumping bass line of a Cowboy Junkies song without sounding muddy. The bass boost switch didn't produce the kind of bass you can feel, but for our taste and for a portable CD player it sufficed. At a midrange volume level we detected a slight hiss, but when we adjusted the volume up or down it went away. I got this cd player because it has all the things on it and its easy to use and program and the color is ice blue and thats cool and the sound is wide open and clear no skipping at all and I don't use batteres that often I love the wall adapter its all i neadSince my old CD player was skipping often and a bit outdated, I decided to try the GPX Blue Ice CD Player. At first, I had my doubts (I had never, ever heard of GPX in my life). Having used it, though, I have to admit that I am very satisfied. First of all, I absolutely love the icy blue color (who wouldn't?) and the way that you can see the spinning CD while you're listening. This player is surprisingly slender and lightweight, so it's easy to carry around. I thoroughly tested the ESP (Electronic Shock Protection) by dropping it, bopping it, and slapping it silly. It didn't miss a beat! And now for the coolest feature: Have you ever been bored out of your skull during a field trip or a looong car drive?(Is the Pope Catholic! ) Well, be bored no more! The GPX player's awesome car adapter kit is easy to use (you don't need to be an electronics whiz to use it), and it enables you to bring your music wherever you go. The bass boost system is also great. Best of all, this CD player is priced very nicely, so you can use the extra money towards a new set of headphones (The included pair is a tad flimsy). If you are a music fanatic (like me!), than I suggest you try out the GPX Blue Ice CD Player. I love it, and you will too!
