Introducing the world’s first true in-ear Wi-Fi headphones. Powered by our state-of-the-art STRIVA technology, Koss STRIVA TAP headphones offer complete freedom and incredible sound with ultra-compact portability. With built-in Wi-Fi receivers, these in-ear headphones give you three ways to listen to music. First, anywhere you have Wi-Fi access, you can stream thousands of free, high-quality internet stations from the internet directly to your STRIVA TAP headphones. Next, plug the included Content Access Point (CAP) into any smartphone, tablet, or MP3 player stereo output, and it will transmit the audio right to the headphones—wirelessly. All that, and you can also use them like standard headphones by plugging them into any stereo device using the included audio cable.
