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.

Very Pleased

Having recently received the new irons I have only played twice with them. Very pleased as they are more forgiving and much lighter than my previous irons. Switched to Senior flex shafts which has been very positive with better results.

Top Notch

Top Notch. Traded in another premier set of irons for the Quantum OS Max Irons. These are better. Straighter is greater. They are everthing they say it is.

Fast and forgiving irons. Great quality as always from Callaway.

Great Game Improvement Irons

I have had these irons about a month and am very happy with them. I have been playing less than 6 months and like the super game improvement features of the clubs as I develop my swing. Now scoring in the mid to upper 80s at 63 years old these irons have made golf fun.

Enjoy

Like butter when hit in the center. Hit a half ball off center or on the lower grooves and the ball still makes the green.

No Difference To Quantum Max

I bought a 6 Iron to add to my existing Quantum Max (no OS) AW-7 Iron set, as I wanted more forgiveness and height to the 6 iron. However I don't believe I see any forgiveness and height improvement over the Quantum Max. So I'm keeping it because it has the same look and feel, but disappointed not to get the extra benefits that are advertised.

Club Head A Little Heavier Helps Come Through Ball

I bought clubs recently and played maybe 5 or 6 rounds. Still have to get acquainted with them but when hit in middle of face ball flys long and straight. Need to get to range to adjust.

Sweet Sticks!

I love the feel and the optional HL spec has yielded immediate results.

Great Irons

I’m extremely happy with these Callaway golf irons. The quality and craftsmanship are excellent, and they feel great in your hands. The irons have a solid feel at impact and has definitely helped add confidence to my game. Callaway continues to make high-quality equipment, and these irons are no exception. Great performance, great quality, and well worth the investment!

Great Irons!

Bought the quantum max about a month ago. Really love them. Very comfortable to handle. Was undecided about buying new irons as my old irons seemed to work well, but what a difference. Glad I purchased!

Love The Quantum Max Os Irons.

I wanted to try the Quantum Max OS so I ordered just the 8 iron to compare it to my Apex irons. More forgiving and I like the wider sole.
