The Mp300 has a separate volume control button compared to the Mp110 which in some cases is very good and some not. The A/B button is used to get back in the menus. It can also be programmed for additional uses.
Below the white cover we find a line-in jack which is placed on the side. After numerous requests the headphone jack has been placed on the top of the player.
The USB port is covered also with a plastic cover to prevent dust etc from getting into the player.

By sliding the white button on the bottom of the player forward you slide out the USB port itself. This is a very nice thing which saves alot of space.
On the back we also have the battery cover which is very easy to slide of when it's time to change the battery on the player.

A normal AA battery has a 26 hour play time which is pretty incredible! You will not loose the battery slot cover since it's stuck to the player. Seems like JOS has done some impovments and listened to their
buyers. On the right picture we have the JOG key which you use to navigate with in the menus and also rewinding and fast forwad.

On the top of the player we find the second headphone jack and also the switch which you use to control if you want the player to be in play mode or to hold (lock) the buttons or just in the FM radio mode.
On the front on the other hand we have the record button along with the play button which you also use to shut and start the player with. The orange logo dissapears when you remove the cover plastic.
You will see a picture without it at the end of the review.

The display is a bit darker blue than the pictures show. On the left though is just the picture you get up that shows which settings are activated and what song you are playing.
On the right I have the same picture but with a little bit better quality.
