You've probably heard by now, but the new iPhone 7 does not have a headphone jack. This is going to be a pain for all kinds of reasons, but if you pick up a pair of Bluetooth headphones you should do just fine. And hey, what do you know, Apple announced a pair of those! The new "AirPods" are completely wireless!
Don't buy them. You'll regret it.
For the past several years, Bluetooth headphones have been called "wireless," but there is only one specific wire they've eliminated: the wire that goes from the headphones to the phone. This is a good wire to eliminate! It gets caught on doorknobs and sometimes shorts out due to bending around the plug. Another wire, however, has been permitted to stay. Over-the-head Bluetooth headphones still have an obvious band (with a wire inside) connecting the two speakers, and more stripped-down Bluetooth earbud designs usually have a wire running between the two buds, one you can just throw behind your neck.
If this seems like a natural step forward, don't be fooled; it's actually a big step back. The wire that connects your earbuds together isn't some annoyance that needs to be eliminated. It is actually a great feature with a few nice benefits. This wire prevents you from misplacing one tiny bud by ensuring the two are connected. These wire-paired buds are easy to fish out of your bag or pocket, for instance.
But most importantly, the wire also gives you an easy way to hang the buds around your neck when you're not using them so you don't have to set them down in the first place. With completely wireless buds, you'll not only have to deal with buds that are easy to lose, but you'll have to deal with them every time you take them out of your ears. Want to take off your headphones and talk to someone for a few minutes? I hope you have fun holding a stray AirPod in your hand, or fishing a loose one out of your pocket a minute later, or have the carrying case on you literally at all times.
