Would it be worth spending more on the Final audio design LAB II over the D8000?

[JD8456]

I'm currently trying to decide over the Final audio design LAB II in ear earphones or the D8000 full size headphones from Final audio design as well. The earphones look to cost about £900.00 pounds more coming in near to £4000.00. However, I've never spent a ton of money on in ear earphones before and wanted advice whether it would be worth it or not over spending about £3000 on the D8000. I've previously owned the Pandora Hope VI headphones and loved them, so brand loyalty makes me want to stick with them. Thanks!
