Input:
Question: Are you serious? Is this item really 8" tall and 5" wide by 1-1/4" thick??  Also does it come with lithium battery or do I have to buy separate thanks
Document: Takes a while to upload songs because you have to use their software, but once loaded, battery lasts forever, sounds really good, and really easy to use. Only thing I would say it needs is a keypad to search artists/songs easier then flipping through all of them.
I had to send it back after 2 weeks of not charging when plugged in. Also, the one that was sent to me was not as pictured in the Amazon picture.
this is a very great mp3 player for the money.. i dont really have anything bad to say about it.
I like the look on the Coby MP707 4G MP3 Player. I can also put photo's on it and music and movies from what it say's on the screen. The only thing that I have a problem with is when it changes songs it takes bout a minute or two before it starts to play the song but other than that issue I am a happy customer and I will be back to purchase more items in the future.
I bought this for my 9 year old son in October for a Christmas present. 5 days after he opened it for Christmas and had used it twice, it died. Can't get a full refund from Amazon since the return period had already past, and of course I had bought accessories too. Complete waste of money - not to mention that the e.music site you need to download songs from is ridiculously expensive. Should have gone with an ipod nano...would have been WAY better off.
Lovelovelove this MP3 player!!! Quite surprised with the quality and ease of use for the price! Would definitely buy again and give a thumbs up to friends and family for future purchases!
very good mp3 player! I play it alot when i go to workout at the gym,the sound it great to listen too
tHIS IS THE BEST MP3 PLAYER EVER. I HAVE HAD OTHER KINDS BUT I HAVE BOUGHT THIS ONE TWICE. I LOST THE FIRST ONE.
I haven't been using the player all that long but so far, I am quite satisfied with the sound and features. I changed the headphones to better ones and the sound made a world of difference.Update! 08/17/12  Much as I enjoyed this little device, it just quit working in June. So, it lasted 6 months...it just died.
Very dissapointed in this product. Tried several attempts to download songs and it wouldn't work. Sending back for a refund.
Answer: It is not that big....in fact it is pretty small.  It came with the battery when I ordered it for my son.  He is 14 and uses the heck out of it and it is still going strong after 6 months.
