Apple introduced AirPods, its wireless earbuds, to deal with the lack of a headphone jack on the new iPhone 7. But those earbuds come with their own problems. As separate left and right pieces, you could easily lose one (or both) and ruin your day. Many competing Bluetooth earbuds are sold in one piece with a strap connecting both sides. This helps keep them together, and if one falls out of your ear, it might not hit the floor because the other earbud is tethered to it.
Necessity is the mother of invention, and sure enough, in less than a week, several vendors have announced straps that keep the AirPods tethered to each other. You can wear the strap behind your neck or under your chin. Spigen offers such a strap and the company makes some nice cases, so it's likely that the strap should be well made too. Spigen even applied for a patent, which is pretty fast work. Spigen's strap costs just $10, but if it helps protect your $159 AirPods, it could be worth it.
