all mp3 players

I got my Joybee several days ago. I really love it. I had read many reviews here and on other websites and many of them were saying to get a different set of headphones for it. So I did that
I got a set of the Sennheiser MX500 and a set of Koss (the Plug)and ordered a set of panasonic but they were out of stock. so I could make a comparison my self. Well here is what I found. The player has plenty of power and I found that the set of earphones that come with the Joybee sound way better than any of the other ones. Just got the sennheiser ones in today and they do not have near the bass capability as the ones the come with the Joybee. Except for the color they look identical in construction, but the joybee earphones sound much better. When I first got them I thought they sounded tiny and cheap and I was using the Koss plugs and they kicked butt especially on the bass end. then I was fiddling around with the stock earbuds and putting them in the ears different ways. And Holly smokes I put them in sideways and they really kicked. Put them in sideways with the little stem towards the back of the ear and sticking out horizontally. the earbud disk itself is in a vertical position with the face of the transducer facing straight forward then stick them in and they hold quite well and sound great. I did not use any cushions with it. Quite comfortable. But other people ears may have varying results. this set has deep bass that rivals a big sub-woofer, and i have to run it at about 8 on the volume scale of 10. So if you consider getting any other earbuds for this unit you wont do any better unless you go to the higher priced models and I have not tested any of them.
As far as the Joybee itself I am real happy with it. It does what I bought it for to play mp3 files. And it does that very well. I cant see much room for improvement in the sound quality and volume.
