@big_greg so are you saying bass is noticeably lacking in the Sennheiser's? For the treble region, which would you say is easier to listen to?
The Sennheisers are not lacking in bass, they are pretty balanced from top to bottom. Both do well in the treble region. The best way I can describe my experience between the two is that the Sennheiser are more realistic and the Focals are more fun. Which one I would pick would vary based on my mood.
