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.

You Will Not Be Disappointed

A step up from my previous irons. So far they are solid. Beautiful sound at contact and easy to work with. 👍

Solid Performer.

Purchased a little over a month ago. Replaced my old but effective Steelheads. It has taken a bit to get use to subtle differences, going from steel shafts to graphite. Clean lines. I would say more forgiving than the previous set. Love the ball flight.

I purchased the Quantum Max OS Irons about 1 month ago. They are absolutely easy to hit. They allow the ball to fly high and land soft. They have already helped lower my scores and make the game of golf more enjoyable.

New Quantum Club Purchase

I bought the Callaway Quantum iron and woods a month ago. Have been able to get 5 rounds in with them. Very smooth swinging and the ball comes off the club head nicely. Been a nice change from my older Pings

Hit ‘Em High

At 75 I had trouble getting the ball airborne. These sticks are tremendously helpful. Beautiful to look at and excellent to hold. They perform as advertised and I’m extremely pleased with my purchase!

Feel Us Off For Me

Bought in early September, used about 5-6 times. Not impressed with the feel of the club. Lost some distance but overall shots were online. I thought oversized would be best for me but just didn’t work. Will try another Callaway club.

Nice sticks

Nice Job Cal

Great Improvement To My Game!

I love these irons. The R2 shaft selection is perfect for my swing. 60 years old and shooting in the 70’s thanks to these clubs. Great purchase.
