I currently own TWS in ear headphones.
I am planning on buying a second pair of headphones since it's almost been 3 years since I brought this one and I feel like trying something new.
I feel like over the head won't be giving the details that in ear can provide, that's just my opinion after trying only one over the head device. Accidentally it broke a year ago.

What are the things I should look for before buying a new device? how should I choose the one that offers good sound quality. I have found one good pair of in ear device that offers in app customisation of the sound.

I'd be happy to post the screenshots of the product in the comment section
