The short version: a regulation basketball measures about 73 dB on the dribble on hardwood, and the WAWAWEWA silent basketball measures 37 dB on the same surface. One is inflated rubber with an air chamber. The other is dense solid foam with no air at all. Everything else follows from that.
The core difference is air
A regulation basketball is a pressurized shell. The air inside it is what gives it bounce, and it's also what makes it loud. The chamber resonates on every impact and amplifies the sound.
A silent basketball has no chamber. It's dense solid foam all the way through, one piece, no seams to fail and no valve to leak. It never needs inflating and it cannot go flat.
That single design difference drives every other difference between the two.
Side by side
- Noise on hardwood: regulation about 73 dB, WAWAWEWA size 7 at 37 dB.
- Weight: a regulation size 7 weighs roughly 600 grams. The WAWAWEWA size 7 weighs 450 grams.
- Circumference: both are 29.5 inches. Same size in your hand.
- Bounce: the WAWAWEWA returns 85% of a regulation ball's bounce.
- Maintenance: a regulation ball needs periodic inflation and pressure checks. A foam ball needs neither, ever.
- Surface: a regulation ball handles indoor and outdoor. A foam ball is indoor only.
What transfers to the court
This is the honest part, and it's where most comparisons overclaim.
What transfers well: ball-handling, hand speed, weak-hand development, rhythm, coordination, and control. Anything where the value comes from repetition rather than exact force feedback carries over cleanly.
What doesn't transfer as cleanly: shooting mechanics and game-speed rebound timing. At 450 grams versus roughly 600, and at 85% bounce, the ball behaves differently under your hand than a game ball does. If you're calibrating a jump shot, calibrate it with a game ball.
The useful way to think about it is that a silent ball buys you reps you otherwise wouldn't get at all. An hour of handle work at 10pm in an apartment is an hour you weren't going to get in a gym.
Where the size difference matters
The size 3 is 22 inches and 250 grams, with the same 37 dB and the same 85% bounce as the size 7. Same construction, smaller scale.
It suits smaller hands and tighter spaces. It's also easier to control for anyone new to ball-handling, because less mass means less correction when a rep goes wrong.
For most people the size 7 is the right choice. It's roughly 93% of what we sell.
What a silent ball is not
It's not a toy, and it's not a game ball. It sits deliberately in between.
It isn't built for dunking, forceful play, or outdoor surfaces. Care is straightforward: dab it clean rather than wiping, keep it indoors, and keep it off rough concrete.
Tens of thousands of players have trained with it since 2023, and the overwhelming majority keep it. It isn't a perfect product. It's a specific one, built to do one thing well.
Two versions, one ball
The size 7 comes compressed and uncompressed. They are the same product with the same specs. Compressed ships vacuum-sealed and expands after opening. Uncompressed is ready immediately. Nothing else differs.

Common questions
Is it actually silent?
No. It measures 37 dB, which is quiet but not nothing. Anyone claiming true silence is overstating it.
Does it feel like a real basketball?
The size is identical at 29.5 inches. The weight and bounce are not. It feels like a lighter ball with a slightly lower rebound, and most people adjust within a few sessions.
Can I use it outside?
No. Asphalt and concrete will wear the foam quickly.
Will it lose its shape?
There's no air to lose. Compressed units expand to full shape after opening and stay there.
