I recently bought some Fischer Amps FA-4E XB out of curiosity. I really tested MANY inears and already gave up in finding a solution that suits me (I have 2 fitted inears and tested 10-12 unfitted ... by the way, I prefer unfitted inears) but damn... those FA-4E really sound awesome. The highs/treble sound just so unbelievably good. I even stopped using my DT770/DT990 at home (which I love).
Best thing: they are only 370€ 
If someone is looking for a warm sounding inear and isn't such a treble freak like me I can recommend the Ultimate Ears 900 - you can get them for around 200€ as refurbished.
