OnePlus is selling Silver Bullet earphones for its flagship OnePlus One smartphone for $15.

OnePlus, the upstart phone manufacturer, is adding a new accessory to its premium flagship smartphone, OnePlus- the all-new Silver Bullet earphones specifically designed for the company's high-end smartphone for $15.

OnePlus revealed the new earphones for the One smartphone on Wednesday. They feature a brushed aluminum and white plastic design to match the smartphone design. The Silver Bullet earphones were put through vigorous testing by twisting the headphone jack 30,000 times to ensure longevity and durability, according to the product listing on OnePlus official site.

The Silver Bullet earphones carry the voice command function with an ease. "The three-button in-line remote with microphone provides responsive control for music, calls, and even your camera," OnePlus explained in the product's description. "Answer the phone, take a selfie, pause, play, and skip to your favorite tracks or change volume by simply pushing a button."

The product is listed as "coming soon" on its official page but TechnoBuffalo expects the orders to start as early as next week in sixteen markets, including Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Taiwan, the United Kingdom, the United States and Hong Kong. Reasonably priced at $15, the Silver Bullet earphones will be a must-buy add-on to the sub $400-worth-OnePlus One.
