Callaway Quantum Max OS Irons

About This Item

Quantum Max OS blends confidence with maximum forgiveness, powerful speed, and consistent carry—all in an oversized shape designed to help golfers hit it more solid across the face.


Modern 360° Undercut

  • The Modern 360° Undercut Cavity is designed to deliver faster ball speeds, higher launch, and more forgiveness across the face, thanks to its advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex where golfers need it most.

Progressive Tri-Sole Design

  • The Progressive Tri-Sole Design promotes cleaner, more consistent contact across the set, with a reengineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention—even on heavy strikes

Next Generation Ai-Optimized Face Design

  • The Next Generation AI-Optimized Face delivers faster ball speeds and more consistent launch, spin, and dispersion by intelligently shaping the face to match real-world impact patterns and expand the sweet spot.

Urethane Microspheres

  • Urethane Microspheres enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.

Oversized, Confidence-Inspiring Shape

  • Quantum Max OS is built for higher launch and maximum forgiveness—all in an oversized shape that inspires confidence at address.

Great Products

Terrific clubs for me and great service from Callaway. Walt always gives great service and club advice

The Light Weight Shaft Feels Great.

I really like these new clubs. I like the looks of the oversized face. I'm short and the half inch shorter feels really good.

Great Clubs

Exactly what i was looking for. I really improve my game

Love Em!

Custom order on a Tuesday and got them the following Friday!! Super fast service! I love these Irons, the oversize and the wide sole are exactly what I'd been missing for a few years. Now I'm back to much more solid shots.

Most Forgiving Irons I Have Ever Played!

I have never been a great ball striker with my irons, and after owning six sets from four different manufacturers, I have finally found a set that I feel comfortable and confident that I can hit the green from 140 yards out. The Callaway Quantum MAX OS with graphite shafts are awesome!!!

Phenomenal Feel And Great Control

First brand new set of clubs I’ve bought( was playing the x-14’s) and they are absolutely worth the money. I’ve never been a shot shape golfer but the control and feel of these irons and wedges are insane. Best purchase I’ve ever made for my golf game

Right Call

Great purchase. I'm happy I upgraded. Love the oversized.

I just purchased my clubs recently. Have used them twice and really like them.

Irons

Not nearly as good as my Rogue irons which I still have in use. I was trying to replace my lost 5 iron.

Nice Clubs For Seniors

I like the size and the looks of the clubs. I am hitting the ball better with these clubs.

Great Feel

So happy with these irons. I’ve had trouble with my irons for years and with these I’m hitting straighter and longer. The feel is amazing. Worth it if you need a confidence boost on your mid game.

Quantum Max Irons

5 rounds with new irons better by 5 strokes on average.

Great

2 months in. Handicap from 13 to 9. Love them now that I’ve dialed in the distances

Upgrade Over Paradym

I’ve now played 4 rounds with the new Quantum MAX OS irons. The ball does fly a little higher and held the green. I really like the 50% increase on trade in, trade up. I also like the badging on the back of the iron. The Paradym would dent/scuff easily.

Newirons

The new quantum irons have worked out great so far. I am completely satisfied with them
