Audio and Connectivity
For audio, the Noir Z4 retains a classic feature: the 3.5mm headphone jack, allowing users to connect headphones without the need for adapters. The presence of a loudspeaker ensures that media playback and calls are audible at reasonable volumes. Connectivity options include Wi-Fi b/g/n with Wi-Fi Direct and hotspot capabilities, Bluetooth 4.0 with A2DP, and GPS for navigation. It's worth noting that the device does not support NFC, which limits its use for contactless payments or other NFC-based applications. The presence of a stereo FM radio might appeal to users who enjoy listening to radio broadcasts on the go.
