At least you get free shipping.

You don't see the brand, these are from Sennheiser Pro Audio

But a 6xx is a 6xx, right? Or no?

yes.

Im traveling to Amsterdam next month and i saw that too as i was checking random prices at Amazon.nl

That made me chuckle

By the way, are there any good audio stores worth visiting in Amsterdam? Probably going to check some sennies and perhaps grab a Fidelio X2hr there

They probably don't have the Fidelios, but just for fun you should check this place -

Crazy town.
I live in Rotterdam, so I usually go to a place in Delft (https://www.earsunlimited.com/), but that's not super close to Amsterdam.

Keep in mind, it's probably more expensive. 21% sales tax.

This isn't a physical store, but

I'm not sure how much of the stuff on their site is in stock, but some of it definitely is -

That's all I've got for you. Have a good trip.

Thank you so much my friend!
