Mitsubishi Trium Astral Audio

Audio

While modern phones are equipped with a myriad of sound features, the Trium Astral kept it simple with monophonic ringtones. It lacked a loudspeaker and a 3.5mm headphone jack, limiting auditory customization and functionality. However, it did have an ascending ringtone feature, which gradually increased the ringtone volume until the call was answered or discontinued.
