Sennheiser HD 400S
Its foldable, 218g build, 18-ohm impedance, and dynamic 18Hz-20kHz drivers deliver crisp, efficient sound in a highly portable design. The built-in omnidirectional mic and inline controls add hands-free calling and track management, a practical touch at this price. Best for budget-conscious users needing a reliable wired headset for voice and casual listening, not for critical music or gaming.
