Query: Not the best player

I used one of these for close to a year before I upgraded. While I found the audio quality to be just fine, I did experience that it ate batteries like nobody's business. I also had some issues with it staying connected to my PC long enough to transfer more than 1 or 2 songs at a time, so I eventually gave up on that and went with just using SD cards. Eventually this player had problems playing in both ears, a problem related to the fact that the headphone jack is only secured in the player with the solder points and eventually the natural stress created by the headphone plug will cause the solder joints to fail, resulting in loss of signal to one ear or other. This is a common issue for lower-priced MP3 players. While I certainly feel like I got my money's worth from the product, I won't buy another.
