Why we tested
Braun’s hand mixer line is frequently overlooked in US markets where KitchenAid and Cuisinart dominate the conversation. The MultiMix 9 makes a specific claim: quieter operation through PowerBell+ motor technology. For bakers with babies sleeping nearby, partners working from home, or simply a preference for a quieter kitchen, this claim matters. We ran it through two months of structured testing to verify whether the quiet operation comes at a performance cost.
How we tested
Standard hand mixer test battery: whipping cream (10 batches), egg white whipping (8 batches), cake batters (6 batches), cookie dough (4 batches), and enriched dough with dough hooks (3 batches). For noise testing specifically, we used a calibrated decibel meter at 30 cm from beaters and at 1 meter from the machine, testing at speeds 3, 6, and 9 simultaneously with the KitchenAid KHM926 and Cuisinart HM-90BCS for direct comparison. We also ran a full 8-minute cookie dough session and a 6-minute whipping session to assess arm fatigue and vibration perception.
Performance
Noise - the clear standout: This is not a marginal difference. At speed 9 (full whipping speed), the Braun measured 79 dB at 30 cm. The KitchenAid KHM926 measured 86 dB. The Cuisinart HM-90BCS measured 85 dB. A 6-7 dB reduction represents roughly half the perceived loudness to the human ear. In a real kitchen, you can carry on a normal conversation while the Braun is running at top speed. You cannot do this with the KitchenAid or Cuisinart at the same speed. At mid-range speeds (speed 5 with cake batter), Braun measured 70 dB versus 74-78 dB for the others. The quiet profile holds across all speeds, not just at high end.
Vibration: PowerBell+ reduces the hand-felt vibration significantly. After 8 minutes of cookie dough mixing at speed 4, our testers reported no vibration fatigue in the hands. With the KitchenAid and Cuisinart under similar loads, mild buzz was noted after 6 minutes. This is subtle but meaningful for bakers who regularly run long hand-mixing sessions.
Whipping performance: Four egg whites to stiff peaks at speed 9: 3 minutes 40 seconds - about 45 seconds slower than the KitchenAid KHM926. Heavy cream to stiff peaks: 2 minutes 25 seconds. These numbers are acceptable but they reveal the trade-off that comes with a 200-watt motor versus 250 watts. The Braun gets the job done; it just takes slightly longer. For meringue buttercream where timing and temperature matter more than raw speed, this 45-second gap is irrelevant. For a baker who’s whipping 8 batches in a day, it adds up.
Cookie dough: Standard 2-cup flour chocolate chip cookie dough at speed 3 for 70 seconds: clean result, no motor strain. A double batch (4 cups) was more demanding - speed 2 for 2 minutes with one scrape to redistribute. The Braun handled it but worked visibly harder than the KitchenAid or Cuisinart under the same load. Stiff oatmeal cookie dough (thick, dry texture) was the Braun’s weakest performance - it completed but motor housing reached 122°F and we gave it a 3-minute rest before the second batch.
Ergonomics and weight: The lightest machine we tested at 2.2 lbs, and the handle is genuinely the best-designed grip in this category. The thumb naturally rests on the speed dial, the balance point is slightly rearward (reducing the tendency to dip the beaters), and the rubberized grip is wider than most. Fatigue was lowest on the Braun in our 8-minute mixing tests.
EasyClick attachment system: The attachment release mechanism is the smoothest we tested. Press the single button and both beaters eject cleanly and simultaneously without any sticking or partial releases. It works with one finger rather than requiring a thumb press. Small detail, genuinely better in practice.
Attachments included: Standard beaters, balloon whisk, dough hooks - all solid quality. The balloon whisk is a wider, more open design than KitchenAid’s pro whisk and performed comparably in egg white tests.
Build quality: Premium-feeling housing, tight tolerances on all attachment sockets, and a satisfying speed dial with positive clicks at each position. The Braun looks and feels like a European-engineered premium product, which it is.
Who should buy this
The Braun MultiMix 9 is the right hand mixer for bakers who prioritize quiet operation and ergonomic comfort, and who primarily whip, beat, and mix standard batters rather than heavy doughs. If your kitchen is in a shared living space, if you bake while others are sleeping or working nearby, or if you have any sensitivity to mechanical noise, the Braun’s noise reduction is a genuine quality-of-life improvement that justifies the $100 price. If outright power is your priority - particularly for stiff doughs - the KitchenAid KHM926 edges it out at the same price. For most hand mixer tasks, the Braun MultiMix 9 is a refined, thoughtfully designed machine that earns its premium position.

Should you buy the Braun MultiMix 9 Hand Mixer (HM9135BK)?
The Braun MultiMix 9 runs meaningfully quieter than every other hand mixer we tested - a real advantage in shared households and open kitchens. The PowerBell+ technology reduces vibration and operational noise without compromising mixing performance. It handles whipping and batter tasks with confidence, though the 200-watt motor shows limitations on very stiff doughs. At $100 it's the same price as premium alternatives, but for quiet operation it has no equal in this category.
Frequently asked questions
How much quieter is the Braun MultiMix 9 than other hand mixers?+
At equivalent mid-range speeds (speed 5), we measured the Braun at 70 dB versus 76-78 dB for the KitchenAid and Cuisinart. At top speed, the Braun measured 79 dB versus 85-86 dB for competitors. This is a clearly audible difference in a real kitchen.
What is PowerBell+ technology in the Braun MultiMix 9?+
PowerBell+ refers to Braun's motor bell design that reduces vibration transmission to the housing and reduces the dominant noise frequency. The result is a lower, smoother sound profile that's less fatiguing over longer mixing sessions.
Is 200 watts enough for cookie dough?+
For standard chocolate chip cookie dough batches (2 cups flour), yes. For very stiff doughs like thick snickerdoodles or crinkle cookie doughs with extra starch, run the mixer at speed 3-4 and allow more time than you would with a higher-wattage machine.
