Part of Sony’s Signature Series, released in 2017 to celebrate the company’s 70th anniversary, the MDF-Z1R headphones have been racking up rave reviews from Head-Fi and beyond. What Hi-Fi? even called them “the finest closed-back headphones we’ve heard”—just make sure you pair them with a quality source. Like the other products in the Signature Series, the MDF-Z1R showcases the company’s cutting-edge technology, Japanese craftsmanship, and high level of expertise. Its 70-millimeter drivers and resonance-free housing produce a wide frequency response up to 120 kHz with strong (but not bloated) bass. All the while, the ergonomic sheepskin pads encase your ears in total comfort and immersive, leak-free sound.
