Great all-around golf ball—soft feel, good distance, and super reliable
Color: Green, Size: One Dozen
Summary: The Callaway Supersoft has become my go-to golf ball. It performs well off the tee and around the greens, and I’ve had zero durability issues. How I use it: Regular play on different course types (dry courses out west and more lush courses in the southeast). Pros: Soft feel that seems to help with both distance and short game Consistent, reliable performance Durable—never had one fall apart Color options are great (green worked well in dry conditions, orange better in thicker grass) Cons: Performance improvements might be subtle depending on your game (could be partially feel/confidence) What I wish I knew: The color actually matters more than you’d think depending on course conditions—visibility can make a big difference. Green is easier to see in more arid environments - think Colorado or Arizona, while orange is more preferred for lush environments like Myrtle Beach or Hilton Head. Fellow golfers will call you "old man" if you use orange for higher visibility. Verdict: A dependable, high-value golf ball that works well for a wide range of players. I keep coming back to these—and the only reason I lose them is my own game, not the ball.

Perfect Golf Balls for My Son’s First Season Playing Golf
Color: White, Size: One Dozen
I bought the Callaway Supersoft Golf Balls for my son’s birthday after he recently started getting into golf, and they were a perfect choice. He was excited to try a well-known golf brand, and these balls have really helped build his confidence on the course. The balls feel soft off the clubface and seem very forgiving for a beginner. My son noticed better distance and straighter shots compared to some cheaper practice balls he had been using. He also likes how easy they are to spot on the course and how durable they’ve been through multiple rounds. As someone newer to golf, he appreciated that these balls perform well without being overly expensive. They make a great gift for beginners or casual golfers who want quality equipment while learning the game. Definitely a solid purchase and a birthday gift he genuinely enjoyed.

Easy to track and great feel
Color: Yellow, Size: One Dozen
I’ve been using these Callaway Golf balls for a while and really like them. The bright yellow color makes a big difference, it’s way easier to track in the air and find in the rough compared to white balls. Super helpful, especially if you’re still working on consistency. They also feel great off the club, nice and soft without feeling too mushy. Pros: Easy to see in the air and rough Soft feel Good overall performance Cons: None so far Overall: Great golf balls, especially if you want better visibility. I’ll definitely keep using these.

Soft, matte and colors
Color: Red, Size: One Dozen
i love the callaway super soft golf balls. The quality is really good, I love the feel of them - I feel I get a good solid hit and they are visible (in the ruff and pine straw). They’re even visible in the water (LOL). The price is right.

Great balls!
Color: Red, Size: One Dozen
I love them, especially the bright red color that helps find the ball in the rough. Callaway Supersoft golf balls are highly-rated for beginners and golfers with slower swing speeds, offering a very soft feel, good distance, and a straight flight path. However, they are known for low spin, which can reduce stopping power on approach shots and around the greens, and durability may be lower than premium balls, especially for faster swingers. Reviewers generally consider them a great value, especially for mid-to-high handicappers who prioritize a soft feel over advanced spin control.
