I paid 379€ for beyerdynamic Aventho wireless back in 2018. Unfortunately the headband lost it’s strength and it doesn’t fit very well anymore (results in poor seal, which is bad for on ears) It was doing 4 years of rough usage though so that’s forgiveable. Best sounding pair of headphones i ever had, easily outperforming a DT 770 pro.

So it definitely was money worth spent. If your purchase gets you a similar experience, i guess that’s fine then.
