Once you get into the contextual menus, pressing up or down on the control pad either does nothing or causes a flashback to several prior screens. It turns out that you use right/left to navigate up/down through the lists in the internal menus--call us crazy, but that seems a bit counterintuitive. If music is playing, hitting the "VOL" key brings up a volume meter that can then purportedly be adjusted with the left/right buttons, but we got varying results with this. It took no fewer than 10 tries to get the volume down to a listenable level.
We could fill pages upon pages with the interface quirks of this player, but suffice it to say that they are enough of a hindrance to negate any value of the plethora of features included. The MP-C7000 offers an FM tuner (with an autoscan function that doesn't really work), a voice recorder, and even video support, but--truly--getting video onto the device is a lost cause in our book. Further, the device doesn't offer one feature that most users demand from an MP3 player: logical music sorting. Select the music icon on the main menu and you're taken directly to the playback screen, with no easy way to find exactly the track you want. In contrast, the playback screen itself displays a wealth of useful info--indeed, that is one of the few useful aspects of the player.
In the end, all of this hardly matters. The Coby MP-C7000 only outputs sound to one channel--the right. We tried a variety of headphones and never managed to get stereo sound. As you might imagine, the experience gleaned from a single earbud was unsatisfying to say the least. Of course, the single channel issue is almost certainly a defect with our sample unit, but even stereo sound wouldn't change our opinion of the player. Music sounded hollow and flat and was lacking bass. At this point, you probably don't even care what the rated battery life is, which is a good thing because Coby doesn't provide one. It hardly matters: even a record-breaking, 1,000-hour cell couldn't convince us to recommend this product. There are far better options out there, and plenty of them.
