The Master & Dynamic MH40 headphones represent a premium over-ear model renowned for their exceptional build quality and refined audio performance. These wired-only headphones feature 45 mm neodymium drivers, delivering rich, detailed sound with deep bass, clear mids, and crisp highs. They offer passive noise isolation through their closed-back design and include a detachable woven cable with dual 3.5 mm jacks (one with an integrated remote and microphone for compatible devices, and a standard 2.00 m cable). This particular pair is in almost unused condition, having seen only minimal prior use. The aluminum ear cups, stainless steel accents, cowhide headband, and lambskin leather-covered memory foam ear pads remain in excellent, near-pristine state, exhibiting no visible scratches, dents, scuffs, or signs of wear on the exterior or headband. The leather surfaces retain their original suppleness and colour without any notable discolouration or creasing from extended wear. Both detachable ear pads are intact and clean. All original accessories are included: the detachable 1.25 m cable with remote and microphone, the 2.00 m standard cable, protective carrying pouch (where applicable), and documentation. The headphones have been stored carefully and tested to confirm full functionality, with no issues in sound reproduction or cable connectivity. A highly collectible example of Master & Dynamic’s original flagship design—introduced in 2013 and re-released as a pure wired icon—the MH40 combines aviation-inspired aesthetics with audiophile-grade performance, free from any battery or wireless considerations. Offered in outstanding, barely used condition, these are ideal for discerning collectors or enthusiasts seeking a like-new, cable-only premium headphone experience.
