Just wanted to give a bump to this. I've been absolutely amazed with the range of my AirPods. They have the best range of any of the 3 pairs of bluetooth headphones that I own. Whereas my other 2 pairs will cut out if I leave my home office and go to the kitchen or the bathroom, my AirPods keep playing strong.

I'm really curious if this is a special function of the AirPods or Apple's W1 bluetooth chip in general. One of my other pairs is an older pair of PowerBeats sports headphones. I would definitely consider replacing them with a new set of BeatsX headphones if that's the case.
