Had a go with a pro version yesterday...extremely quiet in flight you can't hear it once above about 80ft and handles beautifully super stable built like a tank ..I'm impressed.
Unfair to compare the mavic air to the p4p and not everyone can afford £1500 to buy the p4p...the air is what it is...an affordable 4k drone to enjoy flying without a huge outlay of cash.
Selling my pristine condition phantom 4
With 2 batteries 10" Asus tablet,dji nd8 filter boxed as new bought from Jessops in february...selling to buy a normal camera...cost me £1300 all in sell for £999
One vital bit of kit you need is an ND filter...just got a dji nd8 filtet for my p4 and video quality i tranformed...on sunny days you can film at 1.60th of a second at 30 fps and the footage is superb
