4 ms·NFC has distance and bandwidth limits.by borplk 9y agoNFC has distance and bandwidth limits.jonbarker 9y agoI would be OK with the distance and bandwidth limit if it were high quality audio transmitted zero distance (contact) wirelessly, without a pairing step which is currently manual.borplk 9y agoI think the bandwidth is too low for any half-decent quality of audio. Not 100% sure.
