For all its unique looks the LED display is the real innovation of this handset. It has many functions. It can, for example tell you when you've got a text and show its first couple of words. It also shows who is trying to call you if they are in the device phone book, shows the time and provides battery low information. A series of five little icons light up when the LED is active to tell you if you've missed a call, got a voice message, switched to vibrate profile, set an alarm or need to recharge the battery.
What about the music playing pretensions? Well, there is 2GB of built in memory and a microSD card slot on one edge for adding more. The Cocoon supports AAC, AAC+, WMA, MP3 and WAV formats. It will synchronise with your PC via Windows Media Player 11. It also acts as a USB Mass Storage device so PC (and Mac) owners can drag and drop files too.
The phone didn't care where I stored my music on a microSD card - it just found tunes and added them to its library. The Cocoon also incorporates an FM radio.
The headset connector is proprietary at the phone end, and you have to use it to listen to the FM radio. Music playback quality is pretty good through the provided headphones, and they have nice in-ear buds, which I find very comfortable. But if you don't like the headset there is a 3.5mm connector just beyond the handsfree mike, so you can substitute your own earphones. Or you can use a Bluetooth pair as the phone can send stereo to them.
One of the phone's edges is populated with music control buttons, a device lock, and a button that switches between music playback and the FM radio. You can use these when the Cocoon is in its ‘Nest' (a cradle that's provided) to control playback easily, as at this point the phone sits on its side with the controls facing uppermost - fast forward, backtrack, pause or play. The scrolling LED tells you what you are listening to before ending its info display with the time and it'll also tell you what radio station you are tuned into.
