Audio and Connectivity:

The loudspeaker provides decent sound output for calls and media, although the absence of a 3.5mm jack might have been a limitation for users wishing to connect standard wired headphones. However, the phone offsets this with robust connectivity options for its era, including Bluetooth 2.0 with A2DP for wireless audio streaming, and an infrared port—a technology used for basic file sharing. The stereo FM radio with RDS enhances its multimedia capabilities, while the USB 2.0 port offers speeds consistent with connectivity norms of the time.
