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.

Quantum Irons

My transaction went very smoothly and I am enjoying my new Quantum irons.

Love Them And Look Nice

[This review was collected as part of a promotion.] Upgraded from an old set of Calloway’s that were rifle extra stiff. I am older now and decided to move to these. They are easy to hit very forgiving and I just love the irons. They go straight and hit a long way.

Best Irons I Have Ever Owned!

Traded up from Mavrik max irons and very happy I did. Biggest difference in irons I have ever seen! These go where you point them. Irons have always been the weakest parts of my game and these have made a big difference. Hitting more greens and they instill confidence to just swing and let the club do the work. Well worth the investment in my game!

New Clubs!

I could not get into a custom fitting, so I made the decision to go ahead and get them by myself, and I've only had a chance to play one round. They feel good and the extra length is great as I'm 6'1" and I fell this length keeps my body more in line with the ball.

Nice Irons

[This review was collected as part of a promotion.] Very forgiving like the oversized face and very long

Very Forgiving

Very forgiving and good distance. I love the feel and consistency of the irons would highly recommend.

Bet Game Improvement Irons For Mid-high Handicaper

Soft feel off the face, high launching, great distance. Best game improvement irons I have ever gamed. Everything you need nothing you don’t. Thanks Callaway well done.

Great Looking Irons

Looking down at address they look like callaways best iron ever, the big Bertha. Doesn’t get any more inspiring than that.

Awesome Feel!

They feel great, probably 10 yards longer on each club.
