Sennheiser HD 555 to HD 595 Mod
"the only physical difference was an additional piece of foam inside the cheaper HD555 headphones, blocking about 50% of the outside-facing vents"They are likely still making a good profit on the $200.00 "cheaper" pair - just goes to show what a rip-off the $350.00"premium" level of equipment is. Sennheiser should be embarrassed. I hope buyers take notice and send their money elsewhere.
