They've also removed the headphone jack from the newest model iPhone. You can get an adapter that adds it back, but obviously this is fairly inconvenient. Apple's counting on this to get people to toss their old earbuds/headphones. Maybe force is too strong, but it certainly seems physically connected audio devices are now deprecated
You can use some plain old bluetooth headsets like most people have been for years.
If you really dislike wireless for some reason, you can also get lighting earbuds (I think the iPhone 7 actually includes some).
Finally, if you like all these ideas so much, you can avoid purchasing the product you dislike. It's not like they're forcing this onto existing clients by disabling the existing 3.5mm jack.
