I received this machine at the end of the year, hoping a good result with a Koss Pro 4 AAA Titanium headphones (headphone outputs available on my installation had left me skeptical ...). Receipt of the machine, and the first surprise: the size. It really is smaller than I expected ... very serious manufacturing quality, I plug the machine ... And then crénom, what sound !!! Finally, I take my helmet! Its small size is ultimately an asset; its lithium battery power makes it an ideal companion to a xyz-phone. An essay on my Blackberry with and without the amp leaves no doubt is much better with! I have no criticism or reservation regarding this product that I recommend to anyone looking for a good quality / price. As for delivery, without any worries with Amazon.
