Wow .... €50K Headphones ... What next

I didn't think I'll live to see this ... But here it is

Does this mean there is now permission to raise the tide ?!
Lake Baikal in Siberia is the greatest fresh water body on earth.
Anyone wants to pay three times more for everything including hi-fi while being on the same income?

One can't help wondering, shouldn't the headphone cable be replaced with a high end cable of some sort, you know, a pure silver cryogenically treated and machine broken in cable? The Artisan cable springs to mind....
The interesting thing is Sennheiser makes headphones for all at all price points and they all tend to mostly all be good performers at their price points. Will these end that streak? It's not like Sennheiser only caters to the elite although their products have achieved a certain high status in their market over the years. Can any thing sound that much better though? I wonder. Sennheiser has earned a lot of good will over the years and mostly avoided gimmicks I think.
