Audio and Multimedia
A notable aspect of the Amoi M650 is its inclusion of stereo speakers, enhancing audio output for calls and media playback. The device supported downloadable polyphonic and MP3 ringtones, catering to users wishing personalized audio cues. The absence of a 3.5mm headphone jack was a minor limitation, likely offset by the era's growing preference for external speaker use or simplified Bluetooth integrations.
