For over a month I use this mp3 player. Simply brilliant! Good battery life, small, discreet, lightweight (good for running) but well done, for now he reads all my audio with incredible reproduction quality for the price. Concerning the "problem" level too low volume, simply take the old comments and voila. Headphones? they are still in their original packaging, so not tested (I use a Sennheiser HD212 Pro headphones; -) ... as the manual, the grip is a remarkable simplicity and efficiency. In addition you can add a micro SD card if the internal memory were to saturate ... The Amazon service? 5 stars as usual! Overall an excellent investment! as confirmed by the test lesnumeriques.com ...
