The AirPods only connect to other devices via Bluetooth. Unfortunately, they can only pair with one device simultaneously but do keep multiple iOS devices in memory for easy pairing when you open the case.

Like most Bluetooth headsets, the latency is not ideal for watching movies and videos, but it is lower than the Anker SoundCore Liberty Air or the Sony WF-SP700N. They perform admirably well for a non-Aptx low latency device, which should be fine for music but they won't be the most responsive headphones when gaming on your phone or watching a lot of video content. Also, we have yet to test for AAC, but that is more an audio quality codec than a low latency one.
