After the surprise success of Apple's AirPods earphones, the California-based technology giant is planning a push into the high-end market.
Bloomberg reports Apple is working on noise-cancelling, over-ear headphones that they hope will rival similar products from market leaders like Bose and the company's own Beats by Dre brand.
Beats, Bose, Sennheiser, Sony and Skullcandy are all leading players in the headphone market, generating US$20 billion ($27.6b) in annual revenue by 2023, according to Bloomberg.
Researcher NPD Group said last year that sales of AirPods and Beats headphones gave Apple 27 per cent of the wireless headphone market and almost half the dollars spent on the category.
Although Beats also sells lower-priced wireless headphones, a similar Apple-branded high-end headphone would likely cannibalise Beats.
