⭕ Extremely rare Sony MDR-R10 Headphone. These were purchased in 1989 and there were only 2,000 of these ever made. My uncle purchased these in 1989 for £1,500 and these rarely come available for purchase. These have sat in the case for most of the time since they were brought, but have been checked that everything works. They are in excellent condition, and a must for anyone who is seriously into headphones who will understand what an opportunity this is.

Ive heard most of the worlds best headphones, but somehow missed the Sony MDR-R10. Only 2,000 were made. Production started in 1989, and at $2,500 a pair, it was the most expensive headphone in the world. The headphone cognoscenti scooped them all up years ago, and right now MDR-R10s rarely come up for sale. When they do, they usually go for more than $6,000!

The MDR-R10s 50mm Bio-Cellulose Dome Diaphragms are credited with producing the headphones superclear treble and oh-so supple bass. The headphone also sported real lambskin-covered ear pads, and the large sculpted ear cups are made from aged wood fromZelkova trees. Sony did make a few other headphones with Bio Cellulose drivers -- the MDR-CD3000, 1991, MDR-E888 in 1995, MDR-CD1700 in 1996, and the MDR-CD2000 in 2000 -- but those headphones never attained the stature of the MDR-R10. No, its never just one thing that makes the great ones great, its the whole design.
