The main difference between the 94M and 96M is that the 96M is the most advanced version for Series 9 Pro+, with 5+1 synchronised shaving elements for a close shave down to 0.00 mm and greater efficiency (31% more efficient than before), while the 94M for Series 9 Pro has a ProLift trimmer with a 30% wider opening and 35% finer tips to catch more hairs on the first pass.

Both heads have 5+1 cutting elements (5 main blades + 1 Pro/ProLift trimmer). They are compatible between Series 9 Pro and Pro+.

so if I fit the 96M on a braun deri9 pro+ generation 5,would I improve the shave?
