While we think the premise behind Philips' wearable digital audio line is great, it is poorly executed. We do not think an LCD, or a bunch of controls are necessary, but as it stands we are lost in the dark while using this player. There is no power indicator and the controls are just too basic. The Key003 looks great and will be sure to turn heads while in use, but it is certainly a digital audio player that sacrifices functionality for looks. Our recommendation for an MP3 player of this size would be the MPIO-DMK or iRiver iFP-180T. And if you absolutely want the thumb drive Plug and Play capability then you might want to check out the Creative Labs Muvo NX.
