This MP3 any dish of 5 mm thickness fits everywhere easily and it is handy to be able to listen to his music without his entourage to benefit. However, it lacks a small clamp to hold on to when we did not pack to be. The sound quality is good, no sizzle. Navigation, it is not very intuitive. It takes a little getting used to, and the manual is in English. Must juggle the menu button, forward / backward, play and volume. It does not seem sorcerer but the keys have multiple functions, it complicates things a bit. Eg to lower the sound: keep pressing volume, the sound level symbol appears and there, you have to click back, so naturally, we would choose the button up or down. This unit can play the photos or videos, but on such a small 4.5cm screen, I do not see the point, my smartphone is better equipped. The pictures that I have loaded are all pixelated, which makes me not want to try with a video. I have not tried the radio function because I am in the country where my stereo was already struggling to clearly capture a station. Other functions gadgets like calendar, alarm or timer are also included. Its 4GB memory with the possibility of adding a micro SD, coupled with rapid reloading of 1/2 hour to 10 hours of listening, make this mp3 interesting despite its navigation groping. The display shows the current title n ° on the number of titles in total and it is extinguished by economy after a few seconds without manipulation. Apart from the screen, turn off the mp3 using a small slider on / off at the base of the unit. All black, thin, light, soft matte plastic, of 9x4cm size, it is sober, simple, nice. Perfect for just listening to music ... or as my student daughter, listen to his classes in public transport, useful during exam! This mp3 comes with a black and white usb cable headphones! A little surprising ... These are traditional type earphones, which are quite good, but personally I much prefer in-ear that hold much better.
