Mini Metal Clip Mp3 Player Supports up to 8gb Tf Card/micro Sd Card Play Time 5-6 Hours,support Mp3 Format (Without Card Reader, Silver)
These little mp3 players are pretty cool. I bought two of them because I wear them at work and usually work 8+ hours. The seller advertises a 5-6 hour battery life and that is exactly what you get. I have gotten nearly 7 with the volume lower than normal. But I would definitely buy them again. You can't go wrong for the price.
