Why the "but"? The tiny sound considering its size very well and is processed dibasic. A slight drawback: During charging, lit a red light at the rear. I had expected that this goes out or changes color to signal so that the battery is full. Think again, it lights up and glows and lights ... even after 12 hours at the charging cable. Well, that is to get over but brings a star deduction.
Yet another star will be deducted: Unfortunately, my unit the cable was defective. Because I did not want to take the trouble of returning Schickens I told the seller the only one mail. I then got paid 2 euros for the purchase of a new cable. Laudable in itself is, however, costs such a cable (twin out 3.5mm jack and mini-USB for charging) at amazon 5.79.
