First look: Sony's new noise-cancelling XM4 wireless earbuds

Following last year's debut of the Sony âÂÂÂ?ÂÂÂ?WH-1000XM4 over-ear wireless noise cancelling headphones, the WF-1000XM4 earbud version is now on the way. Due to land mid-July at $450, and available in either black or 'platinum silver', these fourth-generation noise-cancelling earbuds bring some key features of their larger over-ear siblings into the tiny in-ear package.
