Audio and Multimedia
Samsung E251 included a loudspeaker and supported downloadable polyphonic and MP3 ringtones, expanding customization options regarding audio alerts. However, users were compelled to forgo the now-standard 3.5mm headphone jack, instead relying on Bluetooth 2.0 with A2DP support to connect wireless audio devices, which was quite forward-thinking at the time. The stereo FM radio with RDS added to the phone’s entertainment options, allowing users to enjoy music and other radio broadcasts on the go.
