I can only speak for 600s and I love the headphones. Had it for 2 years now and just amazing

Got momentum 4 this year for 250. A steal

Personally, momentum 4, I would say 600s, but I have to move it a bit after 3h

That’s unusual

Sennheiser momentum 4 from 400 to 250. Had to do it

You are good. I didn’t wanna buy headphones, but they were 250 from 400 sennheiser momentum 4. I’m still like whyy I don’t need it
