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.

So Easy To Hit These Irons

I have only played a few rounds since purchasing these. Very happy with the results. Have now purchased the 4 and 5 hybrids. Can’t wait to try them.

The Early Results Are In!!

I have used this club a few times and it feels great. The sound and feel of the ball strike gives you a boost in your mental state. I can’t say I hit the ball any better or further yet. I will say after each hit I want to hit three more so I can keep the feeling of my shot with this club in my hand. I believe I will have to try out more of these clubs.

Not For Me

This is my third set of Callaway clubs and they're the worst ones I've ever had please give me back the ones I traded in

Outstanding Upgrade!!

Look great and perform smoother and better than my Elyte Max D irons. Definitely an improvement over something that was already outstanding

Great Irons

Anytime I have purchased new golf clubs I feel I have purchased a good product. Not so when I purchased the Callaway Quantum Max OS Irons. I have had Cobra, Titlest, Tour Edge, and Taylormade irons. These new irons from Callaway without a doubt are the best set I have ever had. I can hit these irons better than any set I’ve ever owned. At 78 years old I feel young again when on the links. What used to be normal 7 iron shot is now an 8 iron. Not only are they long, they are extremely forgiving. I can hit them on heel, or toe and still get the desired distance. As far as I’m concerned Callaway designed the best irons ever for us seniors!!!

I’m 74 and fluctuate between an 11 and 13 index. I got the Quantum Max OS irons a couple of months ago because I needed help getting a higher trajectory and steeper descent with my mid irons. I have been very pleased with the results.
