Tester insights: Performance and impressions
First impressions and aesthetics
669 TC – JB2334
“These are some of the most beautiful irons I’ve ever seen. They were packed extremely well in a padded box, and the heads were wrapped in bubble wrap. The only reason I deducted a point was because of a couple of small dings in the 5 iron.”
669 MB – TheBirdieMasterLOL
“The Sub 70 669 MB irons showed up in perfect condition. There weren’t even smudge marks on the black shafts, and Sub 70 saw my request for red, white, and blue ferrules. The only reason why I am docking a point is because of the grips… they were put on sideways.”
699 V3 – Mason_S
“Right out of the box, I was impressed. Along with my set of individually bubble-wrapped clubs, Sub 70 included a blue hat and a handwritten note. The forged face and unique milled back would make it stand out in any bag.”
699 Pro V3 – Kuehlcam
“Unboxing new clubs is exciting, but realizing the small, thoughtful touches were just as memorable made it even better. The irons arrived well protected, with no loose space or jiggle room inside the packaging.”
Sound and feel
669 TC – JB2334
“As far as sound and feel, I’ve never felt anything so soft. Thin misses are not pleasant at all – yet these irons are so forgiving that those thin misses still go straight, and more than a few thin shots ran up to their target anyway.”
669 MB – TheBirdieMasterLOL
“If I hit a shot in the middle, it felt buttery. Heel strikes had a similar feeling but were a little firmer, while toe strikes were firmer than heel strikes. Extreme misses punished me, but normal misses were very playable.”
699 V3 – Mason_S
“These irons are noticeably heavier than any other irons I’ve used… when you hit a ball in the center of the face, you almost can’t even tell you hit a ball. Overall, I would describe the feel as ‘soft.’”
699 Pro V3 – Kuehlcam
“Throughout the iron set, the sound feedback is reduced to a mellowed thump, barely noticeable by me or my playing partners. Since sound contributes to feel, this subdued audio may also explain the diminished sense of impact.”
Distance and launch monitor data
669 TC – JB2334
“They are virtually the same lofts as my Maltby TS3, and I hit them the same distance, just maybe a little bit higher. The ability to shape my shots and hit a beautiful, high fade has become a huge weapon in my game.”
669 MB – TheBirdieMasterLOL
“The irons go about 5 yards farther than my TaylorMade P7MCs, are more forgiving, and are easier to work both ways. My standard shot goes pretty straight with a fairly high ball flight.”
699 V3 – Mason_S
“I am getting a consistent 10 yards of additional carry with the Sub 70 699 V3 irons. Besides the odd hosel rocket or toe shot, the ball flight is very consistent across the face.”
699 Pro V3 – Kuehlcam
“The carry yardage accuracy and control are superb. While raw distance is impressive, achieving peak height remains a challenge, especially beyond the 7-iron. However, forgiveness is so good that even off-center hits keep me on the green.”
Forgiveness
All testers praised forgiveness relative to their category.
JB2334 (669 TC): “These irons are so forgiving that thin misses still go straight and run up to the target.”
TheBirdieMasterLOL (669 MB): “Forgiveness was very impressive without being overly so. Shots on both the toe and heel ended up in good spots.”
Mason_S (699 V3): “They are very forgiving, and I recommend them as a game improvement iron.”
Kuehlcam (699 Pro V3): “The Pro v3 offers unwavering stability and forgiveness throughout the lineup, particularly in the longer irons.”
On-course performance
669 TC – JB2334
“I played 19 rounds with the Sub 70 669 TC. My handicap dropped from 10.1 to 8.9. The ability to be more creative with my iron shots has unlocked another level in my game.”
669 MB – TheBirdieMasterLOL
“As a scratch golfer, I’m just looking for incremental improvements. My average shot was much better and more consistent with the Sub 70s. I’ve been consistently hitting shots within 10-40 feet.”
699 V3 – Mason_S
“This chart compares my most recent 30 rounds. The trendline is positive, showing a clear improvement in Strokes Gained. All of the Sub 70 clubs performed better, minus the 5-iron, but I expect improvement there too.”
699 Pro V3 – Kuehlcam
“Overall, my entire iron set is showing gains. After analyzing my Trackman data, I was able to adjust for club-specific misses, which notably improved my greens in regulation stats.”
Adjustability and customization
While no adjustable features exist on these irons, testers appreciated Sub 70’s custom build options and responsive customer service.
Mason_S: “Being able to talk to the company directly makes a huge difference to me, and it forms more of a relationship rather than an exchange of goods.”

Conclusion
Final verdict
The Sub 70 iron series for 2025 impressed all four testers with distance consistency, forgiveness and premium aesthetics. Minor build quality issues, such as grip alignment and slight durability concerns, did not outweigh the overall performance benefits.
JB2334 (669 TC): “If you are confident with your irons and looking to take that part of your game to the next level, the Sub 70 669 TC will give you surprising distance, superb feel, and excellent workability… all for half the cost of the bigger OEMs.”
TheBirdieMasterLOL (669 MB): “The Sub 70 669 MB irons are everything that I could ask for in an iron!”
Mason_S (699 V3): “I was thoroughly impressed. They are a great game improvement iron and I recommend them to anyone who is in the market.”
Kuehlcam (699 Pro V3): “The forgiveness and consistency are like a double shot of espresso in a blockbuster finale: powerful, satisfying, and a twist you never saw coming.”
