Pros and Cons

What We Liked

  1. The innovative A.I. face architecture of the Apex Pro 21 Irons creates high COR’s for fast ball speeds, resulting in greater distance on each shot. It definitely improved my overall game.
  2. The forged hollow body construction and urethane microspheres provide a fantastic blend of sound and feel at impact. The softness of the irons was remarkable and exactly what I was looking for.
  3. The inclusion of up to 90 grams of tungsten per iron in the hollow body construction enhances launch characteristics and forgiveness. As someone who occasionally struggles with forgiveness, this feature was a game-changer for me.
  4. The shipping was fast and reliable, allowing me to quickly get my hands on these excellent irons and start using them on the course.
  5. The Apex Pro 21 Irons feature a sleek and stylish design that adds to their overall appeal. They are definitely eye-catching and make a statement on the course.

What Can Be Improved

  1. One of the negative aspects I encountered was a discrepancy between the advertised flex of the shafts and the actual flex received. The clubs were regular flex instead of the extra stiff as advertised, which was a disappointment.
  2. Another issue I faced was the missing 8 iron. It seems there was a mix-up or oversight during shipping, resulting in one club missing from the set. This was quite frustrating and inconvenient.

Quick Verdict

All in all, the Callaway Apex Pro Iron Set is a truly exceptional set of irons that excel in both performance and aesthetics. The A.I. face architecture, forged hollow body construction, and tungsten energy core all work together to deliver remarkable distance, forgiveness, and feel on the course.

Although I encountered some issues with the shaft flex and a missing 8 iron, these drawbacks were overshadowed by the overall excellence of the irons. I highly recommend this set to scratch or single digit handicappers who are seeking a significant upgrade to their game.

Features – What We Found

1. Innovative A.I. Face Architecture

The Callaway Apex Pro Iron Set features an innovative A.I. face architecture. This means that the faces of the irons have been designed using artificial intelligence, allowing for optimal performance and distance. With high COR’s (Coefficient of Restitution), the irons produce fast ball speeds, resulting in longer shots.

This advanced technology ensures that each iron in the set delivers consistent and reliable performance. Whether you’re a scratch golfer or a single-digit handicapper, you can expect improved distance and accuracy from these irons.

Pro-tip: To maximize the benefits of the A.I. face architecture, focus on maintaining a proper swing technique and solid contact with the ball.

2. All New Forged Hollow Body Construction

The Apex Pro 21 Irons are built with an all-new forged hollow body construction. This design provides a remarkable blend of sound and feel at impact, creating an extremely soft feel that golfers expect from premium irons.

The inclusion of patented urethane microspheres further enhances the overall feel of these irons. These microspheres effectively absorb unwanted vibrations at impact, resulting in a smooth and satisfying sensation when striking the ball.

Pro-tip: The forged hollow body construction and urethane microspheres make the Apex Pro Iron Set an excellent choice for players who prioritize feedback and a soft feel in their iron shots.

3. Tungsten Energy Core for Improved Launch and Forgiveness

The hollow body construction of the Apex Pro Iron Set features up to 90 grams of tungsten per iron, the most ever in an Apex Iron. This Tungsten Energy Core significantly improves launch characteristics and forgiveness.

By strategically placing the tungsten weight low and deep in the clubhead, the irons offer a higher launch angle and optimal spin rates. This allows golfers to achieve a more controlled ball flight and land their shots with precision.

Pro-tip: Take advantage of the forgiveness provided by the Tungsten Energy Core by swinging confidently and focusing on maintaining a consistent swing tempo.

4. Improved Spin Robustness for Every Club

The A.I. designed Flash Face Cup architecture in each iron of the Apex Pro Iron Set enhances spin robustness. This means that the irons deliver consistent and reliable spin rates across all clubs in the set.

Thanks to the optimized spin rates, golfers can enjoy improved control over their shots. Whether it’s shaping the ball flight or hitting shots into well-protected greens, these irons provide the necessary spin to help you execute your shots with confidence.

Pro-tip: Experiment with different shot shapes and trajectories to fully utilize the spin robustness of these irons, and remember to adjust your swing accordingly to achieve your desired shot outcome.

5. Exceptional Combination of Sound and Feel

The combination of the all-new forged 1025 hollow body construction and the patented urethane microspheres in the Apex Pro Iron Set results in an exceptional blend of sound and feel upon impact.

Whether you’re a golfer who prefers a crisp and solid feel or one who enjoys a buttery soft sensation, these irons cater to both preferences. The forged construction provides a satisfying feedback on well-struck shots, while the urethane microspheres absorb unwanted vibrations to enhance the overall feel.

Pro-tip: Pay attention to the feedback provided by the sound and feel of each shot to help fine-tune your swing and improve shot consistency.
