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.

Best I've Ever Ownes

Have played several rounds with these irons, and am very pleased. They are very forgiving, and I'm getting more yardage. I could not achieve consistancy with a 5 iron until now. These irons are really improving my game.

Overall A Great Set Of Golf Clubs….

I bought a complete set just two weeks ago and I love them. Well balanced and powerfull.

Great Irons. Easy To Hit, Forgiving And Long

I bought these recently and have played a couple of rounds with them. I love them. Easy to hit, forgiving and good distance plus a higher flight trajectory than my prior Callaway irons.

High Flyer

Same Callaway feel. Gets ball up quicker than I've ever been able to do.

Excellent Product

I purchased the Quantum Max OS irons in late February 2026. To date I have played 3 to 4 times per week with these irons. My shot dispersion has narrowed on average between 3 to 5 yards. I found that a higher ball flight and spin rate were easily achieved when used with the Callaway Chrome Soft ball. My ball flight is mostly straight or with a small cut and very consistent. I highly recommend these irons.
