a7s are nice but the hi end is so aggro. i've got p33s which have the same tweeter and the more experienced i get the more sick of it i become. its great for looking deep into the mix but it doesnt really sound that natural and after long sessions all that hi end hurts my (admittedly already damaged) ears.

i can vouch for the 'natural' focal sound as well as it being extremely easy to hear compression on them.
