Pantech PG-3900 Audio and Connectivity

Audio and Connectivity

For audio, the phone supported MP3, AAC, AAC+, and MP4 formats, and featured polyphonic and MP3 ringtones, reflecting the growing trend towards personalization. It included a loudspeaker but lacked a 3.5mm headphone jack, which was somewhat limiting for private listening experiences. Connectivity options were reflective of the time; it offered Bluetooth 2.0 with A2DP for wireless audio streaming, but it did not support modern wireless standards such as WLAN. The absence of a standard USB interface meant owners had to contend with a proprietary connection for data transfer, which was quite common back then.
