Apple turning up the volume with new headphones

San Francisco

APPLE'S AirPods earphones have been a surprise hit. Now, the company is planning a push into the high end of the market.

The Cupertino, California-based technology giant is working on noise-cancelling, over-ear headphones that rival headsets from market leaders like Bose and even the company's own Beats by Dre brand, according to people familiar with the product's development.
