Michael Piskor has posted a review of the Sony MDR-XB1000 headphones ($300-400 used) at Headfonics. His conclusions:
“Sony, please with a cherry on top…bring this headphone back with a new exterior design. Keep what is amazing about them, but improve it. We are 5-6 years later and the technology has improved drastically since then, you can do it and I’ll be first in line to buy a new XB1000 v2.0 from you!”
