the sound quality is good for a cassette, amplitude interesting volume, several possible equalization (that's a little gadget but it has the merit to be able to solve problems based on the quality of the installation. Do not wait miracle, though) .the button mode useless (anyway, this is the kind of standard remote control as found on a lamp LED that changes color as any low-end hardware). Well, if not, it's pretty well equipped. In the box: cassette, remote control with integrated battery, two loaders, a type cigarette lighter, the other type area, headphones and USB cable. no false advertising, the cassette hosts without problems my 8gb sd card and recognizes. Two major drawbacks, however: the cassette only accepts MP3 (WMA So forget) and frankly track selection is quite problematic. Cassette badly picks up the signal of the remote control and the tracks are (very?) difficult to select (at least I did not understand the intricacies of the craft). In other words, you may have to track all of the memory card in the order (unless, worse, it remains the same artist ... I still have to do tests ...). Warning , it remains practical anyway as we do not take this product for anything other than it is. PS: By the way, she can not play the role of accessory cassette adapter: the jack is an output, not an input !!! (This is evident but it will better said)
