Got mine yesterday morning from Apple and they're already my favorite tech product of 2016.
Let's start with pairing. These make it dead simple to pair these with all of your devices. Open their case next to your iPhone, click the big "Connect" button that pops up, and you're done. They're now instantly paired to your iPhone, iPad, Mac, or Apple Watch. This means you can easily switch between any of your devices with no problems. Moving from your iPhone to your Mac? Easy, just click the sound icon in the top menu bar and click on the AirPods. You'll hear a little "bonk" to indicate they've switched to your Mac and that's it. It really couldn't be easier. Once you're switched, just listen to your music. The first thing you'll notice is that they sound noticeably better than the regular EarPods do. After that you'll notice that they're also surprisingly snug. I worked out with them, ran with them, etc. No matter how much I moved around these wouldn't come out; they didn't even come loose! This is subjective, but for me they have an excellent fit. If regular EarPods fit your ears, these will fit even better. Moving forward, another thing I love about these is their automatic play/pause feature. Need to listen to someone that's talking to you? Simply take an AirPod out and your music instantly pauses so you can hear them. Put them back in and it instantly resumes. It's simple, but works great and is highly functional.
Battery life is lasting around 5 hours for me which is more than enough for my use. The charging case is what really shines here, though. Since they're always in their case – which, might I add, is incredibly tiny (I've added a picture of them next to my chapstick, for scale) and easily fits in even the smallest of pockets – when they're not in use they're always topped up to 100%, so battery life is almost never an issue. When they do inevitably die, however, you won't be without them for long. That's because they charge insanely fast –– I'm talking 20% to 100% after just 20 minutes in their charging case. Very impressive.
Another thing that I'm really loving about these is the connection and lack of latency. They're incredibly reliable and have yet to dropout for me. I can put my iPhone 7 Plus in my room and walk around my house and still hear my music loud and clear from 20+ feet away. I previously was using Jaybird X2's and while those weren't bad, they did dropout numerous times a day (especially with iOS 10). That's not the case with AirPods. Their latency, or lack thereof, is something I never thought I'd see with bluetooth headphones. With my Jaybirds there was always a slight delay between when I'd do things on my iPhone and when I'd hear the sound in my X2's. For example, I'd click the play button on my phone and about second later I'd hear music. Same with pausing, fast forwarding, etc. Somehow, the AirPods don't have that delay. You click Play and instantly hear your music, no delay whatsoever. I've tested out numerous bluetooth headphones and none can match the AirPods in this regard.
Now, let's talk about the microphones. They have absolutely blown me away in how well they work. FaceTime Audio calls are extremely clear and the microphones in each AirPod do an incredible job at cancelling out background noise. In fact, they worked so well that the person on the other line couldn't even tell I wasn't talking directly on my iPhone or that I was even outside where it was very windy and loud with cars and busses going by. Similarly, double tapping to activate Siri and giving commands through the AirPods works perfectly because of these headphones. Double tapping and saying "Call so and so," or to even just give commands like setting a timer hands-free when you're cooking dinner, worked flawlessly as well. If you've seen it, it's almost like the movie Her –– you've always got that little voice in your ear to do things for you. Unfortunately, Siri cannot be activated by simply saying "Hey Siri," although this is likely done in order to save battery life by not keeping the microphones always-on and listening for an activation phrase. This is a non-issue, though since double tapping to activate Siri (also works with gloves/hats on!) works very reliably and with no delay like there is when activating Siri on other bluetooth headphones.
Overall, Apple has done an incredible job with these. It took them a while to get them out – still annoyed they delayed them by two months – but it's clear that they took their time with these in order to make sure they worked flawlessly. If you can manage to grab a pair of these before Christmas these would make for an excellent gift to give to someone (or yourself). I highly recommend these.
