In a Hurry? The Quick Answer
- If your shaver head is black, get the 👉 Braun 32B Replacement Head.
- If your shaver head is silver/grey, get the 👉 Braun 32S Replacement Head.
That’s it. They perform identically and fit all Braun Series 3 models. Your choice is purely for color matching.
The Big Question: Are the Braun 32B and 32S Interchangeable?
Yes, absolutely. The Braun 32B replacement head and the Braun 32S replacement head are 100% interchangeable. They share the exact same cutting technology, fit mechanism, and performance characteristics. The only difference is the color of the plastic housing.
ShaversHead team has tested both cassettes on multiple Series 3 shavers, including the 3040s and 310s. We found zero difference in the closeness of the shave, comfort, or the time it took to get a clean result. Your choice is purely cosmetic.
- Braun 32B: The “B” stands for Black. This cassette has a black plastic frame.
- Braun 32S: The “S” stands for Silver. This cassette has a silver/grey plastic frame.
Choose the one that matches the original color of your shaver’s head. If you don’t care about the color, buy whichever is cheaper or more readily available. The performance will be identical.
Performance and Technology: Absolutely Identical
Both the 32B and 32S feature Braun’s acclaimed SensoFoil™ technology and an independent middle trimmer. This design allows the shaver to cut hairs close to the skin without causing irritation while effectively trimming longer stubble. Our internal teardowns confirm the blades, foils, and internal mechanics are the same across both models.
The Complete Braun Series 3 Compatibility Chart
Finding your model number can be tricky. You can typically find it on the back of the shaver, under the sideburn trimmer, or in the user manual. Once you have it, use this definitive chart.
The simple rule is: If you have a Braun Series 3 shaver, the 32B or 32S head will fit.

Expert Note from William: “I’ve spoken to hundreds of users who were worried about compatibility. I can confidently say I have never seen a Braun Series 3 shaver that the 32B/32S cassette didn’t fit. It’s Braun’s universal solution for this entire line.”
How to Be 100% Sure Which Replacement Head You Need
Still feeling uncertain? Here are two foolproof methods our team uses to verify the correct part.
Step 1: Look at Your Old Cassette
The easiest way is to eject your current shaver head. The model number, either 32B or 32S, is often printed on the plastic housing. If you see that number, you can buy the corresponding Braun Series 3 replacement head with full confidence.
Step 2: Match by Color
If the number has worn off, simply look at the color.
- Is the plastic part of your shaver head black? You need the Braun 32B replacement head.
- Is it silver or grey? You need the Braun 32S replacement head.
Remember, even if you buy the “wrong” color, it will still fit and function perfectly on your shaver.
Why You MUST Replace Your Braun Series 3 Head (Every 18 Months)
Using a dull shaver head is like trying to cut vegetables with a butter knife. It’s ineffective and damaging. Braun’s 18-month recommendation is based on average use, and our testing confirms that performance drops significantly after this period.
Telltale Signs Your Shaver Head is Worn Out:
- Pulling and Tugging: Instead of cutting, dull blades pull at your hair, causing discomfort.
- Skin Irritation: A worn foil can lead to redness, razor burn, and a less comfortable shave.
- Longer Shaving Time: You find yourself going over the same spot repeatedly to get a clean shave.
- Visible Damage: Check the foil for any dents or holes. If you see any, replace the head immediately to avoid cuts.
Replacing the head is the single most effective way to make your old shaver feel brand new, restoring that smooth, efficient shave you first experienced.

Things Needed?
Steps to Install Braun Series 3 Replacement Head
No. The mounting mechanisms and head designs are completely different. You must use a compatible Braun Series 3 replacement head (32B or 32S) for a Series 3 shaver.
For shavers without a Clean&Charge station, eject the cassette after each shave and tap it gently on a flat surface. Use the included brush to clean the internal cutters. You can also safely rinse the head under warm running water.
High-quality non-OEM heads are designed to meet or exceed original performance standards at a more affordable price. They use premium materials for the foils and blades but cut costs on branding and marketing.
Yes, dramatically. Our tests show that a new head can reduce shaving time by up to 25% and significantly increase comfort compared to an 18-month-old head. It's the best upgrade you can make for your shaver.
