Quick Answer
Braun 32B and 32S are the same Series 3 foil-and-cutter cassette design. 32B is black and 32S is silver. The only difference is color: they are fully compatible and interchangeable for a shaver that uses the 32B/32S Series 3 family. Choose the finish you prefer or the option that is in stock; there is no performance reason to prefer one suffix.
The 32B/32S interchangeability does not make either cassette suitable for Braun Series 5, 6, 7, 8 or 9 shavers, which use different head families. If you are unsure whether your shaver uses the 32B/32S family, confirm the complete model or old cassette before ordering. For a confirmed fit, see the ShaversHead Braun Series 3 replacement head page. Its listed options are compatible replacements, not automatically genuine Braun parts.

Braun 32B vs 32S at a Glance
| Question | Braun 32B | Braun 32S |
|---|---|---|
| Cassette color | Black | Silver |
| Part family | Series 3 replacement cassette | Series 3 replacement cassette |
| What the suffix signals | B identifies the black finish | S identifies the silver finish |
| Interchangeability | Fully interchangeable with 32S on a compatible shaver | Fully interchangeable with 32B on a compatible shaver |
| Best buying rule | Confirm the shaver uses the 32B/32S family, then choose black if preferred | Confirm the shaver uses the 32B/32S family, then choose silver if preferred |
| Is one automatically a better shave? | No; the color does not change the intended performance | No; the color does not change the intended performance |
For a buyer, the difference is the finish. Once the shaver is confirmed for the 32B/32S family, either cassette can be used without a fit or performance advantage for the other.
Are Braun 32B and 32S Compatible With the Same Shavers?
Yes. Braun’s current US service pages for 32B and 32S show the same model references:
320r-4, 320s-4, 330s-4, 320s-5, 330s-5, 3000s, 3020s, 3030s, 3000BT and CruZer5.
Those shared listings support the same compatibility path for both finishes. The important boundary is the 32B/32S family itself: either color works where that family is supported. Regional service pages can use different model lists, so compare the complete model reference when you are unsure whether the shaver belongs to this family.
If your shaver is not in the list, use this order of evidence to confirm that it is a 32B/32S-compatible Series 3 model:
- The 32B or 32S number printed on the old cassette or its original packaging.
- The full model/type reference on the shaver or manual.
- A Braun service or parts listing for that exact reference.
- Seller support if the part number and model information still conflict.
How to Identify the Correct Replacement Head
1. Read the old cassette marking
Turn the shaver off and remove the cassette as described in its manual. Look for 32B or 32S on the plastic frame, underside or packaging. This confirms the cassette family; you do not need to keep the same letter when replacing it.
If the old number is missing, use the complete shaver model to confirm the 32B/32S family, then choose black or silver. Color is the only difference between these two options.
2. Record the complete shaver model
Check the back or underside of the shaver, the rating label near the trimmer, the box or the manual. Record the complete reference, such as 3000s, 3020s or 330s-5. “Braun 3” or “Series 3” is too broad for a safe part decision.
3. Compare the model with the part listing
Use Braun’s 32B service listing and 32S service listing as the current US reference. If your exact model is listed on both, either cassette is suitable; choose the finish and stock option you prefer. If it appears on neither, confirm that the shaver uses the 32B/32S family rather than assuming every Series 3 label uses it.
4. Check the product description before checkout
Make sure the listing describes a complete Series 3 cassette, not only a foil or cutter component. Also check whether the seller is offering a compatible replacement or a genuine Braun part. Those are different product descriptions, even though 32B and 32S themselves are interchangeable options.
Does 32B Shave Better Than 32S?
No. 32B and 32S have the same fit and intended shaving performance. The only difference is black versus silver. Shaving results still depend on correct Series 3 fit, foil and cutter condition, cleaning, skin and hair conditions, and the number of passes needed.
Use this rule:
- Choose 32B if you want the black finish.
- Choose 32S if you want the silver finish.
- Either option is fully interchangeable when your shaver uses the 32B/32S family. The old letter does not limit you to the same color.
When You Should Not Buy 32B or 32S
Do not order either cassette yet when:
- Your shaver is a Braun Series 5, 6, 7, 8 or 9 model. Those families use different replacement-head families.
- Your old part is marked 21B and you have not confirmed that the seller’s 32B/32S replacement is intended for your exact shaver. The 32B/32S interchangeability statement applies to those two parts, not automatically to every other Series 3 cassette number.
- The model number is incomplete, worn away or different from the seller’s compatibility list.
- You need a foil-only part but the listing is for a complete foil-and-cutter cassette, or vice versa.
- The seller does not clearly disclose whether the part is compatible or genuine.
A cassette that will not align, seat or click into place is a reason to stop and recheck fit. Do not force it or shave with a loose head.
Which One Should You Buy?
| What you can verify | Best next step |
|---|---|
| Old cassette says 32B | Buy either 32B or 32S. Choose black if you want the matching finish, but the two options are interchangeable. |
| Old cassette says 32S | Buy either 32B or 32S. Choose silver if you want the matching finish, but the two options are interchangeable. |
| Old cassette number is missing, exact model is in Braun’s shared list | Buy either finish after confirming the model belongs to the shared 32B/32S family. |
| Model is not in the shared list | Confirm that the shaver uses the 32B/32S family; once confirmed, either finish is suitable. |
| You are unsure whether the shaver is Series 3 | Identify the full model first; do not buy from the series label alone. |
For a confirmed Series 3 fit, the Braun Series 3 replacement head product page is the appropriate purchase path for ShaversHead’s compatible 32B and 32S options. Review the model guidance, product disclosure and pack details before checkout.
Replacement and Wear Checks
Switch the shaver off before changing the cassette. Release or pull off the old head according to the model manual, then press the replacement into position until it is seated. If it feels crooked, loose or unusually difficult to install, stop and recheck the part number and model.
Braun commonly recommends replacing the foil-and-cutter block about every 18 months, but wear varies with use and cleaning. Inspect it sooner if the foil is damaged, the shaver pulls hair, requires substantially more passes or causes new irritation after correct cleaning and installation.

FAQ
What is the main difference between Braun 32B and 32S?
32B is black and 32S is silver. Color is the only difference, and the two cassettes are fully compatible and interchangeable when used on a shaver in the 32B/32S Series 3 family.
Can I use 32S instead of 32B?
Yes. If your shaver uses the 32B/32S Series 3 family, 32S can replace 32B and 32B can replace 32S. Choose based on color or availability, not performance.
Is Braun 32B compatible with every Series 3 shaver?
32B and 32S are fully interchangeable for the same supported Series 3 shavers. If you cannot confirm that your model uses this family, check the complete model reference or old cassette before ordering; Series 5, 6, 7, 8 and 9 heads are different families.
Is 32B or 32S a genuine Braun head?
The part number is a Braun reference, but a seller’s replacement can be a compatible third-party product. ShaversHead’s linked Series 3 options are described as compatible replacements, not automatically genuine Braun original parts.
What if my old head says 21B?
Start with a 21B replacement for a like-for-like match. Some Braun US service listings show overlapping model references for 21B and 32B, but the parts should not be substituted without confirming your exact model and the desired cutting design. The broader Series 3 replacement head guide explains that distinction.
What should I do if the replacement will not click on?
Stop using it and check the cassette orientation, full model reference and part number. Do not force a mismatched or loose cassette. If those details still conflict, ask the seller or Braun support to confirm the fit before trying another head.
