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.

New Irons

[This review was collected as part of a promotion.] Arrived a couple of days ago and look great. I tried them at the range and they sound and feel great can’t wait to get to the course!

Noticeable Improvement

[This review was collected as part of a promotion.] First time playing this week. Loved the feel, setup specs were perfect. Saw improved ball flight and noticed distance increase per iron. Although this is first time using the new irons, totally satisfied. Would definitely recommend.

Callaway Has Continued To Produce A Great Product!

First of all, I'm a Callaway guy and have played Callaways for over 30 years. I previously had a set of Big Bertha OS clubs but decided after 10 years with those that I would upgrade to the new Quantum OS. GREAT decision on my part because they are pure.

Grat Feel With The Swing And Striking Of The Club

Ijust recenly got the quantum max os irons i have only used them 4 times and so far i think probably the best iron i have ever hit we had amix up on my orignal order but when i called back and discused with my sales mam we got the right set for 9 holes i shot 41 40 39 and 38 at that rate i may be hitting under par thanks to sale man who got me the right fit i have already told several of the guys i play gof with that are thinking about clubs to checkout the quantum series

Quantum Max Os Irons

I bought the quantum max os irons and love them I hit them longer than my previous irons and they are easy to hit.

New Sticks

[This review was collected as part of a promotion.] I recently switched to these irons and have been extremely impressed. The forgiveness is outstanding, especially on mishits, where they still maintain impressive distance and accuracy. Even shots struck off-center feel solid and stay on line much better than expected. They inspire confidence at address and have made the game more enjoyable by turning potential bad shots into playable ones. A great set of irons for golfers looking for consistency and forgiveness.

Great Products

Terrific clubs for me and great service from Callaway. Walt always gives great service and club advice

The Light Weight Shaft Feels Great.

I really like these new clubs. I like the looks of the oversized face. I'm short and the half inch shorter feels really good.

Great Clubs

Exactly what i was looking for. I really improve my game

Love Em!

Custom order on a Tuesday and got them the following Friday!! Super fast service! I love these Irons, the oversize and the wide sole are exactly what I'd been missing for a few years. Now I'm back to much more solid shots.

Most Forgiving Irons I Have Ever Played!

[This review was collected as part of a promotion.] I have never been a great ball striker with my irons, and after owning six sets from four different manufacturers, I have finally found a set that I feel comfortable and confident that I can hit the green from 140 yards out. The Callaway Quantum MAX OS with graphite shafts are awesome!!!

Phenomenal Feel And Great Control

[This review was collected as part of a promotion.] First brand new set of clubs I’ve bought( was playing the x-14’s) and they are absolutely worth the money. I’ve never been a shot shape golfer but the control and feel of these irons and wedges are insane. Best purchase I’ve ever made for my golf game

Right Call

Great purchase. I'm happy I upgraded. Love the oversized.

Ddamian 7

[This review was collected as part of a promotion.] I just purchased my clubs recently. Have used them twice and really like them.

Irons

Not nearly as good as my Rogue irons which I still have in use. I was trying to replace my lost 5 iron.
