A lightweight cushioned metal headband offers durability and a comfortable custom fit. Wearing style choice Two wearing styles are available: hi-fi stereo (Blackwire 5220) for those who want a richer, immersive experience, or monaural (Blackwire 5210) design for those who prefer to leave one ear open.
