Mizuno JPX One Drivers Compared
How the two JPX One heads differ, and why Mizuno's driver line is shorter than its rivals'.
Two heads, not five
Where most brands offer four or five driver heads, Mizuno offers two: JPX One and JPX One Select.
That is a real difference in approach, and it cuts both ways. Fewer options means a simpler decision and less chance of ending up in the wrong head. It also means that if you sit at an extreme — a severe slice, or very high speed with a spin problem — Mizuno may not have a head shaped specifically for you the way a broader range would.
JPX One
The larger footprint and the more forgiving of the two. A bigger head sitting behind the ball, weight positioned to protect off-centre strikes, and an easier launch.
This is the right starting point for the large majority of golfers, including plenty of good ones. Being a strong player does not automatically mean you need the smaller head.
JPX One Select
Compact, with a deeper face. Built for golfers who prefer a smaller shape at address and who strike the ball consistently enough not to need the extra help.
The deeper face matters more than the size does. It suits a golfer who tees the ball a little lower and catches it slightly higher on the face.
What both share
Both use Mizuno’s NANOALLOY face technology, and both offer an adjustable hosel and weighting. That adjustability is the part most buyers under-use.
Two things worth knowing about adjustable hosels:
- Adding loft usually closes the face slightly. Useful if you leak the ball right; unhelpful if you already draw it.
- Adjustability fine-tunes the right head. It does not rescue the wrong one. If you need the setting at an extreme to make a driver work, you are in the wrong model.
Choosing between them
Ask three questions.
What does your strike pattern look like? Impact tape across ten drives tells you more than any launch monitor number. A tight cluster supports Select; a scattered one supports the standard head.
What shape do you want to see at address? This matters more than golfers admit. A head you dislike looking at will not produce your best swing regardless of its specifications.
Where does your ball flight fail? If it stalls and climbs, you want less spin. If it falls out of the sky, you need launch.
Testing a head change without trusting memory
Driver testing collapses under its own recency bias. The last club you hit always feels like the best one, and by the time you get home you are working from a story rather than data.
FocusGolf turns that into a record. It runs on Wear OS, Apple Watch and Garmin, detecting each swing automatically without any sensor attached to the club, and logs swing speed, tempo and shot distance ball by ball. Hit ten with your current driver and ten with the JPX One head you are considering, then read the two blocks back from your session history rather than deciding in the moment.
Fitting tip: Test both heads on the same shaft. Changing head and shaft together tells you nothing about which one made the difference.
