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.

Pleased With My Purchase

I’ve played a half dozen rounds with these and am pleased. I’m a 66 year old golfer, 20 handicap. Using graphite regular flex shafts in them. Really are very consistent for me. Forgiving faces and consistent length. I changed from the 2023 Big Bertha and probably a half club longer and more accurate. They are not distance super improvement clubs but find the green more often than not.

Hit Many More Greens-in-regulation!

I had Titlist irons before I purchased the Quantum Max OS Irons. The Quantum irons are much more forgiving and easier to aim. I have hit many more greens-in-regulation than I did with my Titlist irons.

Best Iron Set Ever

Excellent clubs. I bought Max OS irons with the True Temper DG mid-90 steel shafts. Traded in Elylte flagship irons because I could not hit the Sweet spot on the 7-5 irons plus I launched the Denali graphite shafts too low. Now super happy and once again hitting greens in regulation!!!

Great Value, Feel, And Response

The setup at address with these Max OS irons is very good. It translates to help your swing make a clean solid impact. Great ball fight and distance. An excellent price for an outstanding set of irons.

Straight As An Arrow

Upgraded from AI smokes. These are straighter and higher but retain similar distances.

A Huge Upgrade To My Iron Game

I recently purchased a set of Callaway Quantum Max OS irons, and I have been extremely impressed with them. From the first time I hit them, I noticed how forgiving and easy they are to launch. Even on shots that are not struck perfectly in the center of the face, I still get very good distance and a consistent ball flight. One of the biggest improvements for me has been the confidence these irons give me standing over the ball. They have a great look at address, feel solid at impact, and provide a nice combination of distance, forgiveness, and control. I also really like how easy the longer irons are to get in the air. The overall quality and finish of the Quantum Max OS irons are excellent, and they have quickly become one of my favorite golf purchases. Callaway did a great job designing an iron that is forgiving enough to help on mishits while still providing the feel and performance I want when I make a good swing. I am very happy with my purchase and would definitely recommend the Callaway Quantum Max OS irons to golfers looking for more forgiveness, confidence, and consistency in their iron game.

Easy To Hit Purely

Replaced my 3 year old Big Bertha irons. Slight improvement. Had to recalibrate club-distance selection because they go a bit farther.

Quantum Irons

I love my new Quantum irons. The look and feel is great. I have played with them a few times and they are solid. I have the oversize and it feels like a huge sweet spot. I can't wait to take them out again.

Love How These Irons Appear Addressing The Ball

I made two errors when I purchased the irons; 1) I specified Winn Black Wrap Oversized Grips that were too soft and light in weight thus elevating my Swing Weight and allowing for improper alignment of the club face. So, I changed the Winn grips to Golf Pride Midsize MCC+4 Align with 3 total layers of tape, this change lowered my Swing Weight to C8, thus increasing my Swing Speed. 2) When I ordered the irons, I requested they be built ½ over standard length while overlooking the irons were already ¼ inch over and adding another ½ was not the thing to do. I caught my mistake and had the clubs shortened ¼ of an inch with the new grips, what a difference. great ball flight thru all of the irons. Thank you, Callaway for your continued support of the "Club Golfer."
