According to online store monitor iStockNow the long delayed BeatsX earbuds might start shipping soon-- online Apple Stores appear "all ready for the BeatsX launch."
The Apple store page currently states the BeatsX are "coming February." iStockNow also cites "some activity" on the Best Buy US online store, which lists the earbuds as "coming soon."
The BeatsX were first announced by Apple back in September 2016 together with the iPhone 7 and 3 other headphone offerings, namely the AirPods, Powerbeats3 and Solo3. The BeatsX carry the same W1 wireless chip as the AirPods, meaning they should offer easier pairing and better connectivity with iDevices than rivals using Bluetooth connectivity.
Also included in the earbuds are "Fast Fuel" charging and magnetic tops able to lock together.
