I said it before that Sony has the worst bang for your buck when it comes to headphones than anyone else.
I mean, would you rather get a CD3000 for $450 or a AKG K1000 for $500?
As far as the price of the R10, most of the cost goes into things that have nothing to do with how they sound. I sure that they sound nice and all but do they sound like they cost $4000? Are they that much better than other headphones cost wise?
Let's look at what you are paying for :
The Housing
After extensive testing of materials from all over the world, the heart-wood of mature Zelkova trees was selected as most suitable for the housing of the MDR-R1O. Evaluation was made in terms of hardness, timbre, weight, and overall sound-transferability characteristics. In order to overcome the problem of designing housing that could produce a natural, distortion-free sound, engineers used the FRESDAM (Freeform Shape Design and Manufacture) computer-aided design system. A delicate waveform was carved out of the interior wall, achieving sound expansion and acoustics equivalent to that of a concert hall.
The Headband
The housing position is set automatically when placed on the head, due to a shape-memory alloy employed in the self-adjusting head-band. Regardless of head size, the super-elasticity of the headband applies just enough inward pressure to create the proper acoustic space between the ear and the housing.
The Diaphragm
Using leading-edge biotechnology techniques, a natural fiber (bio-cellulose) produced by a bacteria called Acetobacter acti is dehydrated, then compressed to a thickness of 20 microns in a diaphragm die. The advantage of the ultra-thin bio-cellulose diaphragm is that it can produce the same sound velocity as an aluminum or titanium diaphragm, along with the warm, delicate sound that a paper diaphragm provides. Trebles are sparkling clear, and bass notes are remarkably deep and rich.
The Holder
Hangers made of magnesium that attach the housings to the head-band reduce resonance. Magnesium was chosen because of its excellent vibration attenuation and absorption qualities. To prevent mechanical vibration, such as those of the cord or headband, a housing insulator was placed between the ear pad and the baffle plate.
The Earpads
To provide the ultimate in comfort, Greek lambskin covers the entire earpads, along with the headband and suspender Renowned world-wide for its velvety softness and smoothness, the lambskin affords a luxurious feel that allows even the wearer with the most sensitive skin extended listening comfort.
The Cord and Plug
The cord wires are made of 99.9999% pure, linear-crystal oxygen-free copper to prevent signal loss during transference. A durable, soft silicon insulates the wires, and the insulation is coated in 100 % pure double-woven silk. The OFC plug is double-plated; once with rhodium to prevent signal loss, and the second time with gold to prevent sound quality deterioration from imperfect contact.
