Sennheiser HD 400S
32mm dynamic drivers and 18Ω impedance deliver Sennheiser's clear mids, detailed highs, and controlled bass, with closed-back passive noise isolation. An inline smart remote handles calls and track control, and the 217-gram foldable frame aids portability. Best for budget-focused commuters who need a lightweight wired headset for music and hands-free calls, not critical monitoring.
