The W1 chip extends that quite a bit. My old Bluetooths I'd lose connectivity when I walked into the break room which is about 80' from my desk-I'd lose the signal as soon as I left our room. With my Powerbeats3 that also have the W1 chip they stay connected all the way into the break room around the corner (the 2nd wall kills it)It uses Bluetooth to connect so should have the same range as Bluetooth devices in general, which in my experience at least has been further than I've ever needed!
