Question: what is the difference between braun series 8 and 9?
Answer: The Series 8 battery is better than the current Series 9 generation (92XX models), however Braun recently updated the Series 9 and fitted them with the same larger battery and the same 32-bit MCU. ... Also, the Series 9 is still in my opinion Braun's quietest shaver so far. Compared side by side, the Series 8 is louder.
