Logitech UE 9000. These have been around for a long time and have consistent great reviews. I’ve never listened to them though so I can’t say for myself.

Logitech UE9000. I’m not sure about similarities to the DT770s, but they apparently are a kickass pair of Bluetooth headphones…
EDIT: You might want to buy used…as they are a little bit out of your price range…

The UE9000 have served me pretty well over the years; but you do need to add a thicker leather headband. Hurts the top of your head without it.
