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.

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.

Nice Clubs For Seniors

I like the size and the looks of the clubs. I am hitting the ball better with these clubs.

Great Feel

So happy with these irons. I’ve had trouble with my irons for years and with these I’m hitting straighter and longer. The feel is amazing. Worth it if you need a confidence boost on your mid game.

5 rounds with new irons better by 5 strokes on average.

Great

2 months in. Handicap from 13 to 9. Love them now that I’ve dialed in the distances

Upgrade Over Paradym

I’ve now played 4 rounds with the new Quantum MAX OS irons. The ball does fly a little higher and held the green. I really like the 50% increase on trade in, trade up. I also like the badging on the back of the iron. The Paradym would dent/scuff easily.

Newirons

The new quantum irons have worked out great so far. I am completely satisfied with them

Fantastic Irons

These irons are not only for forgiving, but have added 12 to 15 yards. Excellent quality and craftsmanship. I highly recommend them.

Forgiving Irons

Over the past few years, I've gone from Rogue X, to Elyte X, to now the Quantum Max OS. I opted for the OS over the regular Max as I was primarily looking for forgiveness than any other feature, and while I have only played a few rounds with these irons so far, I believe these are more forgiving than the Elyte X's. It was advertised that these clubs make it easier to get the ball in the air, and that has certainly been the case for me so far. I feel like they interact with the turf very well both in the fairway and rough. The only thing I believe the Elytes have on these is distance. I have not seen any gain in distance at all, or at least not yet. But adding distance was not my goal in trading for these. I was primarily looking for forgiveness and consistency, and I believe these are an improvement over the Elyte X in those areas.

Amazing Clubs

Love these clubs! Trades up from the AI Smokes since the graphite shafts weren’t my style. Hard to miss hit a ball with these.

Quantum Max Os Irons W Graphite Shafts

Great set for the 18 HC. I had Big Bertha from 2004 so it was time to upgrade. I love these irons and how forgiving they are. I’m a little older 59 and these help with distance and keeping the ball in fairway. Great set for a weekend hack that wants to hit straighter and feel good about a round of golf. Highly recommend.
