What the differences mean
At the 7-iron, the 639 CB is 32° and the 699 Pro is 31°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the 699 Pro should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the 639 CB. Across the 7 clubs both sets share, the 699 Pro averages 0.5° stronger, with the largest gap at the 5-iron (25° vs 24°). The pitching wedges are 44° and 45°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the 639 CB 7-iron sits 1° flatter (61.5° vs 62.5°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the 639 CB runs 3-iron to PW (8 clubs), the 699 Pro 4-iron to AW (8 clubs).
The 639 CB is a players iron and the 699 Pro a players distance iron, so they sit one step apart on the forgiveness scale. The 699 Pro is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. The 639 CB trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The 639 CB is listed as forged from a billet with a CNC-milled back and the 699 Pro as two-piece hollow body, TPE resin injected. The 699 Pro's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the 639 CB, at some cost in feel.
Both sets were introduced in 2019, so this is a choice between two models from the same lineup rather than an upgrade: Sub 70 designed them to sit side by side for different players.
Which should you choose?
The 699 Pro is the stronger-lofted set — up to 1° stronger than the 639 CB on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Sub 70 639 CB stronger lofted than the 699 Pro?
No. The 699 Pro is the stronger-lofted set: its 7-iron is 31° against 32° for the Sub 70 639 CB, 1° stronger and worth roughly 3 to 4 yards of extra carry.
What is the loft difference between the Sub 70 639 CB and 699 Pro?
At the 7-iron the difference is 1° (32° vs 31°). The largest gap on a shared club is 1° at the 5-iron, and 6 of the 7 shared clubs differ.
Which is better for higher handicap golfers, the Sub 70 639 CB or the 699 Pro?
The 699 Pro. As a players distance iron it is the more forgiving design, suited to roughly 5 to 15 handicaps who want extra distance from a compact head. The Sub 70 639 CB is a players iron, better suited to roughly scratch to 10 handicaps.
Do the Sub 70 639 CB and 699 Pro have the same lie and length?
Not exactly. At the 7-iron the Sub 70 639 CB is 61.5° lie and 37 inches, the 699 Pro 62.5° and 37 inches. Both can be bent or built to your own fit.
