Image © SennheiserThe Sennheiser Massdrop HD 6XX are open-back, wired over-ear headphones offering a neutral, mid-focused sound signature with excellent clarity and well-matched drivers for accurate imaging. They are lightweight and comfortable for long sessions, with a detachable cable and included adapter, but their 300-ohm impedance means they need a decent amplifier to perform at their best. As a budget-friendly take on the classic HD 650, they deliver strong audiophile value rather than bass-heavy impact or portability.
