Performance Build Quality Comfort Value PRICE $250 AT A GLANCE Plus Musically coherent sound Comfortable velour earpads Moving parts don’t creak Minus Not especially rugged Limited low bass No carry case THE VERDICT The affordable Sennheiser HD 598 is styled differently from its famous and more costly sibling, the HD 600, but is just as beautifully voiced and just as insanely comfortable. The motley crew that lives in my headphone drawer was getting long in the tooth when I decided to add a widely acknowledged classic to the collection. The new acquisition was the Sennheiser HD 600, now more than 20 years and umpteen generations old, and he’s become my go-to guy when I want to spend an evening kicking back with headphones that guarantee total physical and listening comfort. Lately I’ve had a chance to try the HD 600’s little brother, the HD 598. At $250, it lists for $150 less than the HD 600, though as of mid-November it was widely available at major online e-tailers (Amazon, Best Buy, B&H) for $150 to $175.
