Never make noise in the kitchen with these 'silent' appliances

If your morning smoothie routine means waking up the whole house, you know the pain of a loud blender.

Indeed, noise has long equated to power. But Ninja has quietly set out to disturb the competition with its Stealth IQ technology, designed to deliver professional-grade performance without the noise.

Here are our honest thoughts on the Stealth IQ Kitchen System and the more focused Stealth IQ Kitchen System to help you decide which one's best for your kitchen.

Ninja's quiet revolution: Stealth IQ Technology

If it wasn't clear, Ninja has launched two different products that share a few core innovations that make it a game-changer for households with different schedules. We'll explain the differences in a moment, but here are the best features in both.

Stealth mode

This is the titular feature of the blenders, and both units come with a 'StealthShield' to place over the blender to dampen the noise. So fear no more – you can have those early-morning smoothies and late-night protein shakes without waking up the house. In our testing, we found that this significantly damped the noise of the blender, especially compared to older Ninja blender models.

BladeSense technology

Ninja is calling this its "smartest system yet" for blenders. So, they will automatically sense, detect and adjust the speed and timing to deliver smooth, blended results every time. We found the blender to adjust very well to whatever was thrown in there, be it a banana smoothie or a fruit crush with lots of ice.

Serious power

Both Stealth IQ blenders are equipped with a high-powered 1200W AC motor, ensuring that a quiet blend doesn't compromise on power. To complement this, Ninja's specialty blades deliver superior performance, regardless of the produce, and they certainly shredded through whatever we chucked in there!

So what's the right model for your kitchen?

Best for personal use and quick or smaller batches

The Ninja Stealth IQ Duo Power Blender Pro is a more streamlined package for the daily, essential blending tasks. It still delivers the quiet technology, but without the food processor attachments.

It'll serve you well if you like making smoothies, protein shakes, and frozen drinks using the 2.1L main jug and one 700mL cup. If you're not after a serious kitchen powerhouse system, then this is your best choice, offering the same core experience at a lower cost.

Best for large families, serious cooks and meal-preppers

If you're after a purchase that'll replace multiple appliances in one go, the Ninja Stealth IQ Kitchen System and Processor Pro will be your best bet. It's the model built for families, serious cooks and the meal preppers who need an all-in-one kitchen system.

It comes with a full 1.8L food processor bowl that has dedicated blades for chopping, dough mixing, slicing or shredding. You also get maximum kitchen usage out of it with the 2.1L jug and three 700mL cups, making it a good choice for families.

Final verdict

No matter which model you choose, you'll be getting the same powerful performance and promised stealth technology. If you value a powerful blender and don't want to wake up the household anymore, either will be the right choice.
