Audio and Features
While lacking a 3.5mm headphone jack, the M620 compensates with a loudspeaker capable of playing polyphonic and MP3 ringtones. It also features a stereo FM radio with RDS, catering to those who enjoy listening to radio on the move. The dedicated music key is a highlight for music enthusiasts who appreciate easy access to their audio files via the MP3/AAC/WMA player. Despite these features, the lack of internet-based audio streaming due to absence of WLAN capability is a limitation.
