It is very similar to the Sony Ericsson K750 but differs with regards to its media playback software and its cosmetic design changes. The major differences to the K750 are the included 512 MB Memory Stick PRO Duo, the introduction of the Flight mode function where all radio signals are switched off, and the stereo portable handsfree headset Sony Ericsson HPM-70, which features a 3.5 mm headphone jack, allowing the included headphones to be swapped for any other pair of headphones which has a 3.5 mm headphone jack.
