I'm thinking of grabbing Refurbished Sennheiser HD 598 from the outlet.
what do you thing about that?
they are almost half the price of new headphones, they give you 2 year warranty for refurbished headphones, and the shipping is free if you buy something over 100€.
Second hand headphones are always a great deal, and with the warranty etc from a proper outlet it sounds a fantastic deal to me, I'd check if you get a transport bag or something with them as I know from IRL outlet experience with Sennheiser you can normally get one if you ask for it and it's a nice free thing to get
