I received my AirPods (ordered back in Dec) last week and absolutely love them. They stay in my ears way better than the wired ear buds ever did (because there are no wires tugging on them), and audio quality is pretty decent. Since the charging case is compact and pairing is so quick, I find myself using them all the time. This feels like a classic Apple product, something Steve Jobs would have designed.
I also picked up the PowerBeats 3 ($150 on Amazon right now for the black ones), to compare the two and return the one I didn't like. The thing is, the PB3's are great, too! They sound slightly better than the AirPods and I prefer the inline controls rather than talking to Siri. Definitely preferable for the gym, where talking to Siri is kinda awkward. (but I will say, the mics on the AirPods are excellent.. you can practically whisper your commands.. easily the best Siri experience I've had). The other solution is to use an Apple Watch for the controls.
Maybe I'll keep both.
