HTC and JBL partnered up for the HTC 10 launch and announced a pair of USB-C headphones back in April. At long last, the JBL Reflect Aware C Earphones are available for purchase, as first noted on 9to5Google.
These are powered by USB-C and feature adaptive noise cancellation. This will allow you to adjust the amount of outside noise coming through. The earphones are available direct from HTC's online store for $199 (£149 or AU$262) in black or white.
The earphones have a tangle free cord and are sweat proof. These should work with any USB-C device, including the just announced Samsung Galaxy Note 7 along with the Motorola Moto Z and even Apple's 12-inch MacBook.
