The AirPods were originally scheduled to go on sale in October.
Apple also said delivery of AirPods would start next week along with sales at Apple Stores, Apple-authorized resellers and select carriers.
Apple unveiled the AirPod, which is priced at $159 (Rs 10, 734) at the launch of the latest iPhone in September and these wireless earphones had created a big buzz among Apple fans.

The wireless earphones are now available more than 100 countries the US, UK, Canada, Australia and Japan.
They are also on sale in China, Hong Kong, France, Germany, India, Mexico, Netherlands and the UAE.
