Twitter's first investment in hardware belongs to Muzik, a high-end headphone start-up company and creators of the convertable headphones that give users the ability to control their playlists by swiping buttons on the outside of their device and share them on social media. Over the past few years, the company says they’ve raised $18 million, naming Twitter as one of various investors, through their Venture arm.

Twitter’s deal means that music listening and music sharing will be integrated directly into the headphones, as the company will show off some of its features as part of Twitter’s CES display in Las Vegas this week. With the capacity to compete with high-status brands like Apple’s Beats, Muzik headphones are quoted as costing $299 and are supposed to start shipping in May.
