Quick Fit Answer
Buy this Braun 70S replacement head if your older Braun Series 7 shaver uses the legacy 70S cassette system. The safest match is a current head, manual, or previous order that says 70S. If your shaver is a newer Series 7 360 Flex model, or your current head says 73S or 74S, this is not the correct replacement head.
Series 7 compatibility can be confusing because Braun has used the Series 7 name across older legacy shavers and newer 360 Flex generations. This product page is for the older 70S-style cassette family. The broader Braun Series 7 replacement head page and the Series 7 cassette compatibility guide cover the full Series 7 range.
What This 70S Replacement Head Is For
The 70S replacement head is the cassette-style cutting head used by many legacy Braun Series 7 electric shavers. A fresh compatible cassette can help when your shaver starts pulling, skipping short stubble, feeling rough, or needing extra passes over the same area.
This product is designed as a compatible replacement head for supported legacy Braun Series 7 shavers. It is intended to replace the worn foil-and-cutter cassette, not the whole shaver body. It is also not a cleaning cartridge, charger, trimmer attachment, or protective cap.
Match by the replacement-head family first. The model name “Series 7” alone is not enough, because older 70S-style shavers and newer 73S/74S-style shavers are different.
Why Compatibility Matters
The most common wrong purchase happens when a buyer sees “Series 7” and assumes every Series 7 shaver uses the same head. It does not. Legacy Series 7 shavers commonly use the 70S or 70B cassette family, while newer Series 7 360 Flex shavers commonly use 73S or 74S-style heads.
If your current cassette is marked 70S, this is the most direct product match. If your current cassette is marked 70B, check the fit and finish you need before choosing a silver 70S-style replacement. If your cassette is marked 73S or 74S, Braun 70S vs 73S explains the difference between the older and newer Series 7 head systems.
Compatibility Table
| Your shaver or current head | Fit for this 70S page | What to do |
|---|---|---|
| Current cassette is marked 70S | Yes. This is the intended replacement-head family. | Choose the 70S pack size you prefer. |
| Legacy Braun Series 7 models such as many 720, 760, 790cc, 797cc, 799cc, 7840s, 7850cc, 7865cc, 7893s, 7897cc, 7898cc, or 7899cc shavers | Likely fits when your shaver uses the 70S/70-series cassette system. Model naming can vary by market. | Check your current cassette or manual before ordering. |
| Older Series 7 Pulsonic or Prosonic shaver | Often the correct head family, depending on the exact model. | Match the cassette marking first. |
| Current cassette is marked 70B | Same legacy 70-series family in many cases, but color and listing details can differ. | Compare the shape and confirm whether you need silver 70S or black 70B-style finish. |
| Current cassette is marked 73S or 74S | No. This page is not for newer Series 7 360 Flex heads. | Compare 70S vs 73S to confirm the newer head family. |
| Newer Series 7 360 Flex shaver | No. These usually use a newer head system. | Do not order 70S unless your manual specifically says 70S. |
| Shaver model code begins with newer 70-, 71-, or 72-series naming, such as 70-S1000s or 71-S7200cc | Usually not this old 70S cassette. These model codes can look similar to “70S” but refer to a newer shaver generation. | Check the head number carefully before buying. |
| Braun Series 3, Series 5, Series 6, Series 8, or Series 9 shaver | No. These use different head families. | Choose the correct series-specific replacement head. |
| You only know the shaver says “Series 7” | Not enough information. | Check the cassette marking, shaver manual, model number, or the Series 7 cassette compatibility guide. |
Choose 70S If
- Your old cassette is marked 70S.
- Your older Braun Series 7 manual lists the 70S cassette.
- Your shaver belongs to the legacy Series 7 Pulsonic, Prosonic, or 70-series cassette family.
- You want a silver-style compatible replacement cassette for a supported older Series 7 shaver.
Do Not Choose 70S If
- Your current head is marked 73S or 74S.
- Your shaver is a newer Series 7 360 Flex model.
- Your shaver uses a Series 3, Series 5, Series 6, Series 8, or Series 9 head.
- The old cassette shape or mounting system looks different from a 70S-style head.
- Your model number is a newer 70-, 71-, or 72-series shaver code such as 70-S1000s or 71-S7200cc, unless your manual specifically lists 70S.
70S And 70B Finish Note
70S and 70B are closely related legacy Series 7 cassette names, but the finish and exact product listing can differ. 70S usually refers to the silver-style cassette, while 70B usually refers to the black-style cassette. If your current head says 70B, compare the shape and finish before choosing a silver 70S-style replacement.

Replacement Timing
Replace the 70S shaver head when the cassette starts pulling hair, missing flat-lying stubble, feeling hot or rough, or requiring repeated passes. Many buyers replace a shaver head every 12 to 18 months depending on shaving frequency, beard thickness, cleaning habits, and whether the shaver is used wet or dry.
A fresh cassette cannot repair a weak battery, damaged shaver motor, broken head mount, or charging problem. If the shaver will not power on, runs slowly even after charging, or the head does not lock into place, inspect the shaver body before replacing the cassette.
Signs You Need a New 70S Cassette
- The shaver pulls instead of cutting cleanly.
- You need more passes to get the same result.
- The foil looks dented, worn, cracked, or uneven.
- The head feels rough on skin after cleaning.
- The cassette is older than your normal replacement cycle.
- Cleaning no longer improves cutting performance.
How To Replace The 70S Cassette
- Turn the shaver off and remove it from the charger.
- Release or pull off the worn cassette according to your shaver’s head design.
- Align the compatible 70S-style cassette with the shaver head mount.
- Press it into place until it sits evenly and securely.
- Run the shaver briefly to confirm the cassette is seated correctly.
If the new head feels loose, does not sit flat, or will not click into place, stop using it and recheck the model compatibility.
