The AirPods headphones are actually Bluetooth. It's just that they have their own chip to manage the headphones. That said, I'm not sure if there's any way to pair the AirPods with anything other than an Apple device. It may be possible, but the pairing is done using the AirPod case. While there are many cheaper Bluetooth headphones, the popular earbuds with a comparable battery life (6 hours) is the Jaybird X2 which is $149. That's the same price. So, it really comes down to features.
The existing Apple dock has had a headphone jack (and has for several years), so anyone who has an Apple dock doesn't have to worry about the charge and listening problem (at least at their desk). There's also a Belkin cable that's a Y cable for charging and audio (but that's an additional cost).
