We designed our Krave HD Stereo Wireless Headphones with the Qualcomm® aptX™ HD Sound Codec for a truly immersive experience. Enjoy listening to the finer details of your music or movies in high-definition sound with powerful bass and experience the subtle nuances of better than CD quality. Built on the Bluetooth® 5.0 platform, our Wireless Headphones can communicate as Bluetooth® low energy devices, providing a stronger signal for better stability and improved battery life up to 40 hours. We engineered our Bluetooth Headphones with USB Type-C fast charging and a specialized battery that charges 50% faster. In the rare case that your Wireless Headphones run out of power, a 15-minute quick charge will provide up to 5 hours of use. Super comfortable to inspire you to work longer and play harder, we designed the ear cushions with a protein leather wrap, sourced from Korea, to simulate the natural feel of leather on your skin, then we added plush memory foam inner cores, to surround your ears in comfort while reducing ambient room noise.
