Check out this conceptual design of an MP3 player – while we doubt that it will ever supplant the iPod line even if it were to be released, this one has its own quirks with an on/off switch that must be rotated in order to reveal the controls of the player. The wireless earbuds are cool, although there is always a huge risk of losing them due to loose connectivity, especially when you’re making your way through a crowd during rush hour. Like the number of colors it comes in though, making this a functional and cool entry level MP3 player if it ever rolls off the production line, without it ever having a sniff at the iPod’s throne.
