Those three Beats models Apple announced are larger and the earbuds aren't independently wireless. But BeatsX (which haven't arrived yet) is almost the same price, and has double the battery life (10 hours vs. 5). Those could be the better choice for workouts.
This has been an emerging market over the past year, with at least a dozen announced or available wireless options from large manufacturers like Onkyo and Samsung, and smaller startups like Doppler Labs and Bragi.
They do sound good -- I can't yet say they're the best because we're still comparing them with rivals. But they're priced competitively, almost identical to the better "wired wireless" headphones like the BeatsX and Bose SoundSport Wireless.
With AirPods and iOS 10, if a call comes through, you can answer on either the iPhone or Watch and just start talking. You can use them for running and listen to music. Whatever you need. With the Watch, they're seamless...or, almost seamless.
Occasionally, I sometimes had to swipe up and pick AirPods like you would select Apple TV in AirPlay. So, not always magical and seamless. But they still felt like the buds Apple should have sold with the Watch all along.
You can use just use one by itself, to take phone calls. Either bud will work the same way, and it'll switch seamlessly if you change earbuds. It's pretty clever. But you can't play music this way: both buds need to be in.
