Our Verdict
Sony MDR-7506
Sennheiser HD 25
Both the Sennheiser HD 25 and Sony MDR-7506 have utilitarian designs prioritizing repairability. You can replace almost every part of these headphones. However, besides the metal hinge that flips the Sennheiser's left ear cup forward or backward, they're plasticky headphones but lightweight. Their long cable is straight and detachable, and these headphones fit on your ears. The Sony are plastic, but they have metal integrated throughout the housing. While they're over-ears, they have shallow ear cups. Their long coil cable is surprisingly hefty but not detachable, even though you can unscrew and replace the drivers. They're designed for monitoring sound production, while the Sennheiser are meant for DJing and casual listening.
