Is there any difference between the beats wireless studio 2 and the brand new studio 3 wireless headphones?

I currently have the beats pro that I bought a few years ago and I have the new iPhone 8 and it doesn't take a headphone jack unless you buy the special adapter which isn't godly expensive like $5-7. But to me that defeats the purpose of the phone. I was just curious as to if there are any key differences between the two and if so, what are they? Which would you prefer the two? Or maybe even keeping my headphones and getting the adapter?

There's no Practical difference between one Piece Of Junk and another.
