My MDR7506 gets thrown around and crammed into many places and those survive well. There are two differences, one not so good, one.
Is the headphone cord coiled like other studio monitor headphones? No. Straight w/ very nice sturdy plug. MDR-7560 has coiled version. What materials are used for the headband and earpads? Headband is same as MDR-7506 but ear pads of better quality faux leather ( Auray sheep skin pads are the best to replace it with once original pads gets worn out ) Do these cover the ear completely, and are they closed or open back? No they do not cover the ear completely; they only sit on top of the ears but form a seal around it. These are closed-back headphones. Are these 40 or 50mm drivers? Also, are the magnets neodymium like the 7506? * Format: Sealed dynamic type driver unit: 40mm, dome type (CCAW adopted) * Maximum Input: 1,000 mW, impedance: 63Ù, sound pressure sensitivity: 106dB/mW * Playback frequency range: 5 ~ 30,000 Hz, * Cord Length: (without cord) about 200g: about 2.5m, Plug: stereo standard plug, mass
