It has a mic array. Fewer microphones, but I wouldn't necessarily immediately conclude that it's worse. Testing would tell. 720p is fine for videoconferencing, it's very rare that the software and the network supports anything higher. I'll take 720p with a good lens over 4k with a crappy lens any day.
