Koss KEB 9i (192584.101)
Wired connectivity and an inline microphone provide basic functionality at a minimal cost, though the 16.8 overall score reflects significant audio compromises. Its pink color and bundled mic offer a simple, no-fuss solution for voice calls and casual listening. This product is best for users who need a disposable backup headset for occasional calls and prioritize price over any measure of sound quality.
