I currently own a Marshall Major with a Sansa clip+ (Rockbox firmware, with a corrected bass for the Major).
I am looking for in ears because of the isolation, i had a soundmagic PL30 back in the days and I was looking for in ears less than 150€ (I'm French).
I was thinking about those five :
Denon AH - C710, 100€
Phonak Audéo PFE 111, 120€
Etymotic HF5, 100€
Jays Q-jays, 130€
Yamaha EPH 100, 150€ more or less
For the Yamaha EPH 100, i heard about it yesterday but I didn't see any reviews on it as I think it's not available right now.
By the way I listen to those kind of stuff :
