The K660 doesn’t have any features that will make it stand out amidst other Sony Ericsson phones. It comes with regular business features like calendar, notes, schedules, stopwatch, timer etc. As for connectivity, it’s 3G-enabled with HSDPA and has a VGA camera in front for video calls. Also available are EDGE and Bluetooth with A2DP compatibility. It comes with Google Maps preinstalled.

The 2 megapixel camera is decent. If you like playing with or touching up your images, the PhotoDJ software is really handy and a lot of fun to use. As in all Sony Ericssons, this too has a VideoDJ for editing video files and a MusicDJ for creating ringtones. The games may not be too great but they are entertaining. TrackId is also available.
Battery life is quite good. With normal usage you’ll get a little over a day and a half on a single charge.
