After several hours of various tests and comparisons with several lossless formats and several earphones and headsets, while comparing with a small Sansa Clip + (Rockboxé) and my Galaxy Note 4 (ROOTE + fx plugin audio viper) ben .... C ' sucks !!!!! My Sennheiser Momentum did not specially to sing lighter or defined either with the ALAC, FLAC, mp3 or AAC 320Kbps. The audio bitrate disproportionate to contribute nothing at all with this so-called audiophile player if not a huge place on the micro SD. Worse, I do not perceive the difference between a 320kbps mp3 and FLAC. So no, no, no, this is not the pearl that will get you a big slap in the face by revealing to less than 100 as the years you were deaf. Reading all these tests on the canvas in all languages for hours, I expected a revolutionary audio processing ... Nope.
In presenting things in context, this is a very good player, finished well, fair for the price. I enjoyed the camera itself, its interface is not too bad. Roulette convenient to navigate. IPods first generation it seems. It is relatively compact compared to other players called audiophiles.
I recommend it anyway because at that price (especially compared to an iPod or other), you have a beautifully crafted device, compact, which manages micro SD and provides a sound very honest but not transcendent as some would have us believe. For my part, the spending of the 100 given the small difference in sound with the devices already in my possession is not justified.
