BenQ-Siemens M81 Audio and Connectivity

Audio and Connectivity

The M81 lacks a loudspeaker and 3.5mm audio jack, utilizing vibration and downloadable ringtones for alerts. While Bluetooth connectivity allows for basic wireless operations, the absence of WLAN, positioning, and radio options marks the phone as relatively stripped-down compared to its successors. USB 2.0 provides for wired connectivity, reflecting the technology norms of the time.
