It would appear as though the brand new AirPods 2 are currently available in brick-and-mortar Apple Stores, according to 9to5Mac.
Their article states that not all Apple Stores have them right now and that only select stores currently have them available to customers.
AirPods 2 are $159 without the wireless charging case, but will cost $199 for the wireless charging case. The wireless charging case alone is $79.
Be sure to check your Apple Store physically or simply check the Apple Store app to see if your nearest Apple Store has AirPods 2 available for purchase. Get them while you can because they probably will not last that long and that this is a great opportunity to get the newest AirPods.
