Beats Fit Pro already have 30 hours of battery life with the charging case and the earbuds themselves get 7 hours with ANC off. Also they support Adaptive EQ.
So the only actual differences are:
1. 4 ear tips vs 3
2. 12% smaller charging case
3. Slightly more rounded design to the earbuds

Your own link to the Beats Fit Pro clearly states it is 24 hours of total battery life, and 6 hours of bud time as I mentioned. The Powerbeats Fit is rumored to be 30 hours total battery life, and 7 hours of bud time.
"Up to 6 hours of listening time (with ANC turned on) plus an additional 18 hours provided by its pocket-sized charging case." (There are also other big headlines like "24 hours battery life!" attached to various athletic models showing off the Beats Fit Pro.)
