Looking for solid headphones for around 100€

Hello, I am a total newbie headphones wise and I am looking for an upgrade. I am currently using some audio tehnica ATH-M30x.

I mostly need them for gaming and music (I listen to hip-hop, alt r&b, clasic rock and hyper pop).

Looking for some headphones that have better sound quality than my current ones, decent build quality and wireless.

Won't mind going over 100€, but would rather keep the price as low as possible while still maintaining quality (not from a first world country, every euro saved counts 🙏)

That would be all, thanks for reading!

(Chose closed back but I don't have a preference, I listen to music only when alone)
