These ones: https://www.sennheiser-hearing.com/en-DE/p/hd-560s/ckyy9r5q0016i0c96sk5d9tog/

They're generally said to deliver the sound-quality of medium-grade studio headphones for the price of low-grade ones. But that also means, aside from the sound quality, these are really basic headphones.

You should also mind that they're open-back. So, they have no noise cancelling, neither active nor passive. You have to use these in a silent room.
