The features most liked by the people were the great overall look and the design of the badge, besides the length of the irons, which is a bit longer in comparison to other irons. The latest technology that has been administered in the making of the Callaway Big Bertha B21 Irons includes:

Flash Face Cup (AI)

Every iron in this set has its very own unique face architecture. This has been designed to enhance the ball speed to reach greater levels as well as to provide more consistency in the spin of the ball. The technology has been built on the top of the 360 Face Cup, and the flexion delivered at impact gives the ball extra speed.

Tungsten Energy Core

The addition of a considerable tungsten weight in the head means the center of gravity is in the core of the clubhead, which aids the golfer in higher launching without disturbing the high speed of the balls.


The Callaway Big Bertha B21 Irons have a wide sole and are offset, which means the hosel is placed a little ahead of the head, giving the player more confidence in hitting the ball. This not only makes for better turf interaction but helps to promote easier launches, ball flights that are straighter, and a lower spin, which helps increase the distance of your shots.

Urethane Microspheres

The urethane microspheres featured in the club assist in absorbing the unwanted vibrations. They also helped to improve the sound and feel of the irons on impact.

Performance – Callaway Big Bertha B21 Irons Review

The Callaway Big Bertha B21 Irons’ performance is similar to the Callaway’s Mavrik irons set as their clubhead features are similar. Having said that, the Big Bertha B21 irons seem to have a higher launch, and the microspheres featured aid in dampening vibrations very well. This and the fact that the B21s have a wider sole than the Mavrik irons mean the B21s provide a better MOI.

The Callaway Big Bertha B21 Irons are more suitable for recreational or weekend players because of their higher launch trajectory and their fast face. Amateurs and average golfers will see an instant improvement in their shot distance and in their ball flight with the Big Bertha B21s.

When we talk about the Callaway Big Bertha B21 Irons being extremely forgiving, there are three main reasons for them being so. The first is due to the offset featured on these irons, which obviously offers more forgiveness to those golfers, particularly right-handers who struggle to keep their ball from flying towards their right. The next reason for the B21 being more forgiving is the wide sole of the irons, which provide golfers with a bigger ‘sweet spot’ and makes sliding your club through the turf easier. Finally, the last reason is that the high launch trajectory that these irons provide means even shots you scuff or miss will still fly high and long.

The Callaway Big Bertha B21 Irons can be used to play well and perform in almost any condition. Whether it is sand or thick rough, the irons perform forgivingly, and the wide sole helps in stopping your club from driving into the sand/rough.

The iron’s trajectory is, as we mentioned earlier, high and also direct, the long irons and the mid irons are easy to launch, and thus, you can enjoy all the advantages of the irons while you play.

Having the Callaway Big Bertha B21 Irons in your golf bag gives the golfers the confidence that they are looking for. The B21 irons are great looking, and the blue color instead of the orange that MAVRIK comes in is more appealing to the eyes. Also, the logo in the center is really attractive.

The Callaway Big Bertha B21 Irons are well appreciated by high handicappers. The wide soles, the thicker than usual top line, and the offset, which many might not like, is hidden well by the curve of the head.

According to some reviews, the sound and feel of the Callaway Big Bertha B21 irons are not comfortable. The feedback at impact is minimal, which could be a negative mark for some. This poor feedback will make it difficult for golfers to find the difference between their sweet spots and their mishits.

Our Final Thoughts

The Callaway Big Bertha B21 Irons are quite costly. However, they are worth every penny as they offer the average golfer everything they desire: fast ball speeds, high launches, stability, and the utmost forgiveness. They are especially suitable for beginners or those who have handicaps of 20 or higher. So go ahead, buy a set of Callaway Big Bertha B21 Irons and enjoy the best game of golf with the confidence that they will aid you and provide you with more forgiveness than many other irons on the market.
