Yep, more venting = more bass due to bigger airflow until it backfires eventually and the airflow focus is lost but yea fully closed is a lot less bassy than a little vented usually. Most basshead cans have a little venting, fully closed without venting usually only go up to about 5dB boost. On XB series it probably gives like 10dB boost by the vented design, covering the holes up completely changes the bass bigtime.
I hope adjustable venting mechanisms become more common in the future, it can't be a bad thing to have a bass-adjustment on the headphones themselves which involves no digital processing or anything, just physical design changes. It makes the headphones more versatile and increases the chances to fit the consumer's taste/needs. Great for DJs as well as consumers that use both headphones at home and on the go (where you might need like 3~5dB extra bass to compensate for the loud environment noise versus listening at home). Different settings for stage & studio = perfect.
