Pros and Cons

All things have their good and bad attributes.

So does this golf set. Before analyzing specific features, let’s have an overall look at this item.



  • Embedded sensors cost extra when activated


Design and Technology

Cobra has made a few modifications to the shape and size of this new product.

Their aim is to promote their values and improve their game-changing elements.



This version is constructed with a low  Center of Gravity (CG) and high Moment Of Inertia (MOI) to satisfy distance and forgiveness at the same time.

As a result, the completed product takes on a unique shape.

That is not the end. The golf set utilizes the SPEEDBACK design.

By adding a thin belt of steel onto the sole, the developer gives us a club that has weight focused on the head.

Thanks to this feature, it can provide a lower CG without changing the sole width, thus increasing the balls’ speed and power.

On the other hand, developers equip the model with 32 extra grams of tungsten in the lower heel and toe areas.

With more mass, the club is more stable and resistant to twisting.

Although golfers may feel that it is heavier in the head than other models, the club can guarantee to launch balls high and far.


How It Works: New Cobra F9 Speedback irons

In the reviewed generation, each of the clubfaces and grooves is Computer Numerical Control (CNC) milled.

According to Cobra, this method is usually just for forged products and not manufactured ones.

The milled faces are flat with groovy lines, capable of giving clear-cut lofts with ease.

What’s more, the irons apply the Progressive Spin Technology together with the Progressive Hosel Lengths.

Each club in the set has different designs from one another.

In the long irons group, there are grooves milled into V-shape with short hosel length to enhance strength and height.

Likewise, the mid-irons have U-grooves milled and boosted CG for better control and accuracy.

Finally, the GW and SW irons with the highest hosel lengths and CG can ensure a controlled trajectory flight.

Look & Feel

As mentioned above, the irons are all milled.

Not only helping in performance, but they also elevate players’ style thanks to the thin lines and slender appearance.

The chrome-plate structures bring them a higher level of durability and a more intriguing look.

However, the plating can be rather annoying for players in an intensely bright environment, because it can reflect light and temporarily blind you.


When playing golf with the F9 irons, you can’t help but enjoy the responsive feel it produces.

That is thanks to the PWRSHELL and E9 face technology.

Like technology from other producers, the E9 technology gears the club with a really thin face with variable thickness.

It can be down to 1.8 millimeters at the narrowest point.

This feature helps to enlarge the sweet zone, as such, giving more power to off-center strikes.

Evolved from the previous models, the PWRSHELL contains a new internal Speed Channel that is only 1.2 millimeters.

This product can absorb energy and channel it to the ball as extra forces for better performance.

Furthermore, a three-pieced multi-material insert is included in the long irons.

It is a combination of aluminum, acrylic foam, and  Thermoplastic Polyurethane (TPU).

This small medallion plays a big part in demoting impact vibrations, which also helps create a much softer and receptive response.

Of all the golf products available on the market, this iron set is the first to balance forgiveness and distance.

It is common knowledge for any golf expert that these two are two sides of the same coin.

But the Cobra brand changed all of them.

By optimizing the SPEEDBACK tech, developers have merged the low CG with high MOI features and delivered unexpected results.

“Never has a game improvement iron set had the perfect blend of distance and forgiveness, until now,” said Tom Olsavsky, Vice President of R&D of Cobra Golf.

Undoubtedly, this product is advanced.

Aside from the above advantages, it can also ensure stability and durability thanks to the chrome coating and milled faces.

Value For Money

If you are still wondering whether to buy this golf set or not, you should convert its advantages and even drawbacks into monetary value.

As a matter of fact, the price of this product is quite reasonable compared to other similar clubs.

If you want to play golf seriously or want to have a good game-improvement iron, this item is highly recommended.

Not only for its physical attributes, but it can also promote good control over ball flight and trajectories.

This item, however, might be over budget for some.

Worry not! We made sure to provide you with some similar irons in the following section.

How many clubs are there in this set?

There are seven clubs available in this set.

There are seven lengths divided into three groups: long irons (4-6 irons), mid-irons (7-9 irons), and the wedges.

Are putters included in the iron set?

We are sorry to inform you that this set only consists of irons.

For higher-end sets from the Cobra manufacturer, the irons, woods, and putters are sold independently.

Does this set have Cobra Connect?

Yes, indeed. Each club of the set is equipped with Cobra Connect grips.

In case you activate this feature, you will have additionally gifted sensors for other clubs for free.

Can I purchase the set but without the Cobra Connect Arccos app equipment?

Sadly, no. The models are equipped with sensors in the grips linked to the Arccos Caddie mobile app.

For any users who don’t want to pay for this feature, it is optional.

If you do NOT activate it, you don’t have to pay the fee.

Do the irons have different lengths that can fit tall players?

As far as we know, each club can be lengthened up to 1.5 inches.

However, it’s still best to keep the iron as it is.

If you adjust the club lengths and they suffer any damage, we do not have any responsibility concerning your actions.


That’s all you need to know from the Cobra Golf F9 irons review.

In the end, this item fits the bill and can be a valuable asset for any golfers.

We hope that our review can help you in making decisions to purchase your ideal golf set.
