There aren’t many headphones with as much heritage and history as the Sennheiser HD 600. The fact that you can still waltz onto the Sennheiser website and buy a pair, despite the model being well over twenty years old, just goes to show they’re still a respected icon and part of the headphone market furniture.
Over the years, a number of new versions have launched, including the HD 650 and HD 660, not to mention the very latest version we are testing here; the Sennheiser HD 660S2.
