Sony has decided to update the WH-CH520 and WH-C720N to coincide with the arrival of its WH-CH710N earbuds. Available globally, the new versions of its popular audio products are said to be in response to the increased popularity of 'soft, muted tones' in electronics and beyond.https://www.notebookcheck.net/Sony-releases-new-refreshes-of-popular-wireless-over-ear-headphones.986701.0.html
